     BACKGROUND 
     Item delivery optimization provides for dynamic delivery route optimization when a destination may be mobile. In some situations, recipients for ordered items may be mobile and/or may be situated at a non-fixed location. For example, restaurant food ordered via counter service may need to be provided to patrons who are free to select their own table, or medications may need to be delivered to patients in a hospital who may move from room to room for exams, tests, procedures, etc. Similarly, mail packages may need to be delivered to office workers whose work locations may change due to reorganizations, remodeling, travel between office locations, meetings in conference rooms, etc. Conventional approaches address this problem by delivering the items to a location specified at the time the order is placed, or by forcing the delivery courier to locate the recipient manually. These approaches often result in delays in the delivery.

     DETAILED DESCRIPTION 
     The following detailed description refers to the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the following description to refer to the same or similar elements. While embodiments of the disclosure may be described, modifications, adaptations, and other implementations are possible. For example, substitutions, additions, or modifications may be made to the elements illustrated in the drawings, and the methods described herein may be modified by substituting, reordering, or adding stages to the disclosed methods. Accordingly, the following detailed description does not limit the disclosure. Instead, the proper scope of the disclosure is defined by the appended claims. 
     Item delivery optimization may be provided. There are many situations in which items need to be delivered to various recipients, such as food orders in a restaurant or mail and packages throughout an office building. In many of these situations, the person responsible for delivery of these items may not know where the recipients are currently located. For example, workers in a flexible environment may often move between desks or change areas to coordinate with other workers. For another example, patrons at a counter service restaurant or food truck may order and pick their own place to sit or wander around while waiting for their food to be ready. In such cases, it would be helpful for the person responsible for delivery to not only be able to easily locate the recipients, but to work out an optimal and efficient delivery route. 
     Traditional approaches to route optimization are often described as solutions to the ‘shortest route problem’ or the ‘traveling salesman problem’. These solutions include, but are not limited to Dijkstra&#39;s algorithm, the Bellman-Ford algorithm, the Floyd-Warshall algorithm, and Johnson&#39;s algorithm. Such mathematical approaches are well known when the endpoints of a routing calculation are fixed, such as when a road network is mapped to identify a route for a global positioning system (GPS) navigation device. 
     For example, a road network can be considered as a graph with positive weights. The nodes represent road junctions and each edge of the graph is associated with a road segment between two junctions. The weight of an edge may correspond to the length of the associated road segment, the time needed to traverse the segment or the cost of traversing the segment. Using directed edges it is also possible to model one-way streets. Such graphs are special in the sense that some edges are more important than others for long distance travel (e.g. highways). There are a great number of algorithms that exploit this property and are therefore able to compute the shortest route a lot quicker than would be possible on general graphs. 
     Many of these algorithms work in two phases. In the first phase, the graph is preprocessed without knowing the source (origination) or target (destination) node. The second phase is the query phase. In this phase, source and target node are known. The idea is that the road network is static, so the preprocessing phase can be done once and used for a large number of queries on the same road network. The algorithm with the fastest known query time is called hub labeling. 
     In scenarios such as restaurant food delivery and mail delivery described above, the pre-processing can be done based on building schematics, and may include factors such as one-way doors (often used in restaurant settings), elevator availability and speed, major pathways and hallways versus side corridors, and measurements that take into account the necessity of moving equipment through certain areas. For example, delivery carts of a known width may be needed to move heavy or large packages, and the pre-processing phase may evaluate which hallways are suitable for such a cart as opposed to those that may be too narrow, that utilize doors that may not accommodate the cart, or areas which are not accessible at all, whether due to space constraints, lack of elevator access, lack of security access, or similar restrictions. 
     The pre-processing phase is particularly important in scenarios in which the recipients may be moving around. In such cases, the query phase may need to be recalculated each time a recipient is determined to have changed locations. For example, a mail delivery courier may be distributing packages to several people on the same floor when one of the recipients is determined to have changed floors. The courier&#39;s route may then be updated to complete the deliveries on the current floor before redirecting that courier to the recipient who has moved. 
     The technical effects of some embodiments of this disclosure may include establishing control of access to networks and resources for user devices when access lists may not be predefined, and reducing and/or eliminating the burden of predefining access lists to control access to networks and resources. Moreover, the technical effects of some embodiments may include enhancing network access control by assigning specific access rights based on access lists to client devices authorized to access associated network beacons and resources. 
     Other technical effects of some embodiments of this disclosure may offer group management solutions to managing content access and distribution. For example, users of a sales group may have read access to marketing documents and presentations, while users in a marketing group may be able to edit and/or annotate the market documents. Similarly, users in an accounting or business services group may be the only ones with access to enterprise financial documents. These access controls may be provided by distributing authorization credentials to devices associated with users of the respective group. Each user may then authenticate to their device, such as by inputting a username, password, authentication key, and/or biometric data, before the device may access and/or retrieve the content authorized for distribution to that device. These authentication types are provided as examples only and are not intended to be limiting as many other types of user authentication are in use and/or may be contemplated in the future. 
     Content access may be further limited by policies that enforce other compliance restrictions based on properties of the device such as time, location, device security and/or integrity, presence of another device, software versions, required software, etc. For example, educational settings may designate student and instructor groups. These groups may be further assigned to specific classes such that only student group members associated with a given class may access content associated with that class. Further, edit access to the content for the class may be restricted to the user(s) in the instructor group and/or student group members may be permitted to add content that only the instructor may view (e.g., homework assignments.) In some embodiments, the instructor group user(s) may be able to push content to student group user(s) and/or activate temporary control of the students&#39; devices to prevent the devices from accessing non-class related content during class time. 
     To reduce the cost of ownership of user devices and cellular and/or data service charges associated with use of such user devices, an enterprise such as an educational institution and/or a business may implement a “bring your own device” (BYOD) policy to allow an employee to use his/her personal device to access enterprise resources rather than provide the user with an enterprise owned user device for such purpose. To support such a BYOD policy, a user device administrator (i.e. IT administrator) may manage a group of personally owned user devices, via a management application executed by a management server in communication with the user devices over a network, to provide the user devices with secure access to enterprise resources. 
     The user device administrator may enroll user devices into the management system to monitor the user devices for security vulnerabilities and to configure the user devices for secure access to enterprise resources. The user device administrator may create and/or configure at least one configuration profile via a user interface provided by the management system. A configuration profile may comprise a set of instructions and/or settings that configure the operations and/or functions of a user device, which may ensure the security of the accessed resources. The user device administrator may, for instance, configure an enterprise email configuration profile by specifying the network address and access credentials of an enterprise email account that the users of the user devices are authorized to access. Other configuration policies may include, but are not limited to, hardware, software, application, function, cellular, text message, and data use restrictions, which may be based at least in part on the current time and/or location of the restricted user device. The user device administrator may thereafter deploy the configuration profiles to specific user devices, such as to groups of user devices of users with similar roles, privileges and/or titles. 
     Access credentials may uniquely identify a client device and/or the user of the client device. For example, the access credentials for a user may comprise a username, a password, and/or biometric data related to facial recognition, retina recognition, fingerprint recognition, and the like. Access credentials related to a device may uniquely identify the device and may comprise, for example, a unique hardware identifier such as a GUID (Globally Unique Identifier), UUID (Universally Unique Identifier), UDID (Unique Device Identifier), serial number, IMEI (Internationally Mobile Equipment Identity), Wi-Fi MAC (Media Access Control) address, Bluetooth MAC address, a CPU ID, and/or the like, or any combination of two or more such hardware identifiers. Additionally, the access credentials may be represented by a unique software identifier such a token or certificate, based at least in part on the aforementioned unique hardware identifiers. 
     The user devices may also have access to personal configuration profiles that may be created by the users of the user devices. The user devices may, for instance, have access to a personal email configuration profile that was created by a user of the user device to provide access to her personal email account. Thus, a user device enrolled in a BYOD management system may have more than one configuration profile for a given use of the user device, such as a personal email configuration profile and an enterprise email configuration profile that are both used for accessing email accounts on the user device. 
     The user devices may be instructed to enable and/or disable certain configuration profiles according to authorization rights specified by the user device administrator, such as location and/or time-based authorization rights. For example, a BYOD policy may specify that user devices enrolled in the BYOD management system are authorized for personal use outside of the workday and are authorized for business use during the workday. Similarly, a BYOD device may be restricted to enterprise uses while in work locations and/or prohibited from accessing enterprise resources while outside of secure work locations. To implement such a policy, a user device administrator may instruct the user devices to toggle between personal configuration policies and enterprise configuration policies based on factors such as the current time and/or location associated with the user device. 
     The current time may be based on the current time at the current location of the user device, which may be determined by GPS, Wi-Fi, Cellular Triangulation, etc., or may be based on the current time at a configured primary location associated with the user device, which may be the primary office location of an employee user of the user device. As an example, time-based configuration profile toggling may be provided by instructing a user device to enable business configuration profiles and disable personal configuration profiles while the current time is between 9 AM and 5 PM at the current location of the user device, and to disable business configuration profiles and enable personal configuration profiles while the current time is between 5 PM and 9 AM at the current location of the user device. 
       FIG.  1    illustrates a networked environment  100  according to various embodiments. The networked environment  100  includes a network  110 , a client device  120 , a remote server  130 , a compliance server  140 , and a physical access point  150 . The network  110  includes, for example any type of wireless network such as a wireless local area network (WLAN), a wireless wide area network (WWAN), and/or any other type of wireless network now known and/or later developed. Additionally, the network  110  includes the Internet, intranets, extranets, microwave networks, satellite communications, cellular systems, PCS, infrared communications, global area networks, and/or other suitable networks, etc., and/or any combination of two or more such networks. Embodiments consistent with this disclosure are described below in connection with WWANs (as illustrated in  FIG.  1   ); however, it should be understood that embodiments described herein may be used to advantage in any type of wireless network. 
     In some embodiments, the network  110  facilitates the transport of data between at least one client device, such as client device  120 , the remote server  130 , the compliance server  140 , and the physical access point  150 . Client devices may include a laptop computer, a personal digital assistant, a cellular telephone, a set-top device, music players, web pads, tablet computer systems, game consoles, and/or other devices with like capability. Client device  120  comprises a wireless network connectivity component, for example, a PCI(Peripheral Component Interconnect) card, USB(Universal Serial Bus), PCMCIA (Personal Computer Memory Card International Association) card, SDIO (Secure Digital Input-Output) card, NewCard, Cardbus, a modem, a wireless radio transceiver (including an RFID transceiver), and/or the like. Additionally, the client device  120  may include a processor for executing applications and/or services, and a memory accessible by the processor to store data and other information. The client device  120  is operable to communicate wirelessly with the remote server  130  and the physical access point  150  with the aid of the wireless network connectivity component. 
     Additionally, the client device  120  may store in memory a device identifier  121 , user access credentials  122 , a device profile  123 , and potentially other data. In some embodiments, the device identifier  121  may include a software identifier, a hardware identifier, and/or a combination of software and hardware identifiers. For instance, the device identifier  121  may be a unique hardware identifier such as a MAC address, a CPU ID, and/or other hardware identifiers. The user access credentials  122  may include a username, a password, and/or biometric data related to facial recognition, retina recognition, fingerprint recognition, and the like. Additionally, the device profile  123  may include a listing of hardware and software attributes that describe the client device  120 . For instance, the device profile  123  may include hardware specifications of the client device  120 , version information of various software installed on the client device  120 , and/or any other hardware/software attributes. Additionally, the device profile  123  may also include data indicating a date of last virus scan, a date of last access by IT, a date of last tune-up by IT, and/or any other data indicating a date of last device check. 
     The client device  120  may further be configured to execute various applications such as an “enterprise access application”  124 . The enterprise access application  124  may be executed to transmit a request for a physical access credential. One such credentials are received, they may be stored on the client device  120  for later reference and/or transmission, possible via communication system  125 . Communication system  125  may be the same or different than the wireless network connectivity component previously discussed, include the same or different communication abilities, and may at least be specifically able to communicate with physical access points  150 , discussed below. 
     The client device  120  may also be configured to execute other applications such as, for example, browser applications, email applications, instant message applications, word processing applications, spreadsheet applications, database applications, and/or other applications. For instance, a browser and/or word processing application may be executed in the client device  120 , for example, to access and render network pages, such as web pages, documents, and/or other network content served up by remote server  130 , the compliance server  140 , and/or any other computing system. 
     The remote server  130  and the compliance server  140  can each be implemented as, for example, a server computer and/or any other system capable of providing computing capability. Further, the remote server  130 , compliance server  140 , and any other system described herein may be configured with logic for performing the methods described in this disclosure. Although one remote server  130  and one compliance server  140  are depicted in  FIG.  1   , certain embodiments of the networked environment  100  include more than one remote server  130  and/or compliance server  140 . At least one of the servers may be employed and arranged, for example, in at least one server bank, computer bank, and/or other arrangements. For example, the server computers together may include a cloud computing resource, a grid computing resource, and/or any other distributed computing arrangement. Such server computers may be located in a single installation and/or may be distributed among many different geographical locations. For purposes of convenience, the remote server  130  and the compliance server  140  are each referred to herein in the singular. 
     Various applications and/or other functionality may be executed in the remote server  130  and the compliance server  140 , respectively, according to certain embodiments. Also, various data is stored in a data store  131  that is part of and/or otherwise accessible to the remote server  130  and/or a data store  141  that is part of and/or otherwise accessible to the compliance server  140 . The data stored in each of the data stores  131  and  141 , for example, may be accessed, modified, removed, and/or otherwise manipulated in association with the operation of the applications and/or functional entities described herein. 
     The components executed in the remote server  130  include a authentication service  135 , and may include other applications, services, processes, systems, engines, and/or functionality not discussed in detail herein. As used herein, the term “authentication service” is meant to generally refer to computer-executable instructions for performing the functionality described herein for authorizing and distributing physical access credentials  136 . The authentication service  135  is executed to receive a request for physical access  136  from an enterprise access application  124  executed on a client device  120  and to determine whether to grant or deny the request  136 . Upon determining to grant the request  136 , the authentication service  135  may then send physical access credentials  134 , as will be described. 
     The data stored in the data store  131  of the remote server  130  may include, for example, approved device identifiers  132 , approved user access credentials  133 , physical access credentials  134 , and potentially other data. The approved device identifiers  132  represents a listing of device identifiers  121  that have been pre-approved for potential accessing physical access credentials  134  which will entitle holders of client devices  120  to physical access at physical access points  150 . The approved device identifiers  132  may have been previously provided to the remote server  130  by a system administrator and/or the like. The approved user access credentials  133  represents a listing of user access credentials  122  that have been pre-approved for potential accessing physical access credentials  134  which will entitle them to physical access at physical access points  150 . 
     The components executed in the compliance server  140  include a compliance service  143 , and may include other applications, services, processes, systems, engines, and/or functionality not discussed in detail herein. As used herein, the term “compliance service” is meant to generally refer to computer-executable instructions for performing the functionality described herein for authorizing the device characteristics of another device, such as a client device  120 . The compliance service  143  is executed to determine whether the device characteristics of the client device  120  comply with the compliance rules  142  that are stored in the data store  141 . For instance, the compliance service  143  may identify the device characteristics from the device profile  123  of each client device  120 . Additionally, the compliance rules  142  represents a listing of hardware restrictions, software restrictions, and/or mobile device management restrictions that need to be satisfied by the client device  120  for use of physical access credentials  134 . 
     In some embodiments, hardware restrictions included in the compliance rules  142  may comprise restrictions regarding use of specific client devices  120  and specific client device features, such as, for instance, cameras, Bluetooth, IRDA, tethering, external storage, a mobile access point, and/or other hardware restrictions. Software restrictions included in the compliance rules  142  may comprise restrictions regarding the use of specific client device operating systems and/or other applications  125 , internet browser restrictions, screen capture functionality, and/or other software restrictions. Mobile device management restrictions included in the compliance rules  142  comprise encryption requirements, firmware versions, remote lock and wipe functionalities, logging and reporting features, GPS tracking, and/or other mobile device management features. 
     The compliance service  143  may determine whether the device characteristics of a client device  120  satisfy at least one of the restrictions enumerated in the compliance rules  142 . For example, the compliance service  143  may determine that a client device  120  that has a camera, Bluetooth capability, and is executing a specified version of an operating system is compliant with the compliance rules  142 . As another example, the compliance service  143  may determine that a client device  120  that is associated with an external storage unit and has screen capture functionality enabled is not compliant with the compliance rules  142 . All of these restrictions discussed above may affect whether the client device  120  is entitled to use a given physical access credential  134 . In some embodiments, however, the compliance service  143  may not be used and physical access authorization may be determined solely based on approved user access credentials  133  and/or approved device identifiers  132 . 
     A user operating a client device  120  may wish to receive at least one physical access credential  134  so that the user may physical access a building, location, door, gate, drawer, filing cabinet, storage unit, cabinet, etc. In some embodiments, the user may interact with an input device to manipulate a network page displayed by a locally executed application, such as a browser application, to generate the request for physical access  136 . In some embodiments, the user may manipulate a user interface generated by a locally executed application to generate the request  136 . In either case, the user may provide login information and/or the application may automatically retrieve the login information from the memory of the client device  120 . Login information may be, for instance, a unique user name, a password, biometric data, and/or other types of user access credentials  122 . The application may then communicate the request to the enterprise access application  124 , which may generate and transmit the request  136  to the authentication service  135 . In some embodiments, the enterprise access application  124  may itself receive the input from the user directly and then transmit the access request  136  to the remote server  130 . 
     Upon receiving the request  136 , the authentication service  135  determines whether to grant or deny the request  136 . In some embodiments, the authentication service  135  may first authenticate the client device  120  and the user operating the client device  120 . To this end, the authentication service  135  determines whether the device identifier  121  associated with the client device  120  matches one of the identifiers listed in the listing of approved identifiers  132 . For instance, the device identifier  121  of the client device  120  may be included as part of the request  136  transmitted by the enterprise access application  124 . In some embodiments, the authentication service  135  may request the device identifier  121  from the client device  120  in response to receiving the access request  136 . Upon identifying and/or receiving the device identifier  121 , the authentication service  135  determines whether the device identifier  121  matches one of the approved identifiers  132  stored in the data store  131 . In some embodiments, the authentication service  135  may authenticate the client device  120  dynamically by determining whether the device identifier  121  is within a predetermined range of approved device identifiers  132 . In some embodiments, the authentication service  135  may authenticate the client device  120  dynamically by performing an algorithm on the device identifier  121 . 
     Additionally, the authentication service  135  may also authenticate the user operating the client device  120  by determining whether the user access credentials  122  associated with the user match one of the credentials in the listing of approved user access credentials  133 . For instance, the user access credentials  122  associated with the user on the client device  120  may be included as part of the access request  136  transmitted by the enterprise access application  124 . In some embodiments, the authentication service  135  may request the user access credentials  122  from the client device  120  in response to receiving the access request  136 . Upon identifying and/or requesting the user access credentials  122 , the authentication service  135  may determine whether the user access credentials  122  matches one of the approved user access credentials  133  stored in the data store  131 . In some embodiments, the authentication service  135  may authenticate the user operating the client device  120  without also authenticating the client device  120 . In other words, certain authenticated users may be authorized to gain the requested physical access regardless of what device they used to submit the physical access request  136 . 
     In some embodiments, having authenticated the client device  120  and the user operating the client device  120  as authorized to receive the physical access credential  134 , the authentication service  135  communicates with the compliance service  143  to further authorize the client device  120  to receive the physical access credential  134 . In some embodiments, the compliance service  143  authorizes the client device  120  by determining whether device characteristics of the client device  120  comply with applicable compliance rules  142 . For instance, the compliance service  143  may identify the device characteristics of the client device  120  from the device profile  123 . All or part of the device profile  123  may have been provided by the client device  120  in conjunction with the request  136  and/or may be subsequently requested from the client device  120  by the authentication service  135  and/or the compliance service  143 . The compliance service  143  then analyzes the device characteristics to determine whether the software restrictions, hardware restrictions, and/or device management restrictions defined in the compliance rules  142  are satisfied and returns the result of the determination to the authentication service  135 . In an alternative embodiment, the authentication service  135  may include and perform functionality for determining whether the client device  120  complies with the compliance rules  143 . 
     If the authentication service  135  determines and/or receives a determination that the client device  120  is authorized, the authentication service  135  then associates the client device  120  with at least one physical access credential  134 . In some embodiments, the authentication service  135  sends the physical access credentials  134  to the client device  120  and authorizes the client device  120  to use such credentials in connection with accessing physical access points  150 . In some embodiments, the authentication service  135  may also send the physical access credentials to physical access point  150 . 
     In some embodiments, the physical access credential  134  may be revoked at any time by the remote server  130 . Revocation may occur for any number of reasons, including but not limited to, a change in device profile  123 , a change in approved device identifiers  132 , a change in approved user access credentials  133 , expiration of a defined time period, and/or a request from the user of the client device  120 . 
     In some embodiments, the physical access point  150  is an electro-mechanical device capable of sending and/or receiving information, and in response thereto opening a physical barrier, for example a building, location, door, gate, drawer, filing cabinet, storage unit, cabinet, etc. Depending on the embodiment, the physical access point may or may not be in communication with network  110  and servers and devices connected therewith. In these embodiments, the physical access point may have authorized physical access credentials  134  embedded and/or stored therein, either in a ROM-type storage unit, and/or in a non-networked RAM-type storage unit. A non-networked RAM-type storage unit could be updated locally by direct connection via USB and/or the like, with additional security mechanisms to prevent unwanted tampering/changing of the embedded/stored physical access credentials  134 . 
     The physical access point  150  may include a data store  151  for maintaining data and/or applications which relate to determining whether a client device  120  may be allowed access by the physical access point  150 . In some embodiments, the data store  151  may only include a single access code and/or datum that is expected to be matched by any client device  120  providing the same, thereby entitling the client device  120  to access beyond the physical barrier. In some embodiments, the data store  151  may include a plurality of access codes, any of which may be matched by a client device  120  to verify authority to access beyond the physical barrier. The physical access point may have a processor to implement such methods. 
     The physical access point  150  may also include a physical lock actuator  152 , for example, a solenoid and/or other electro-mechanical actuator, which is operable to physically unlock the physical barrier upon command to do so by the physical access point  150 . The physical access point may also include a communication system  153  for sending and receiving information with a client device  120  (for example, an RFID transceiver, a wireless radio transceiver, a near field communication device, and/or the like). 
       FIG.  2    is a flow chart setting forth the general stages involved in a method  300  consistent with embodiments of this disclosure for providing item delivery optimization. Method  200  may be implemented using elements of operating environment  100  as described above and a schematic block diagram  400  as described below. Method  200  is described below with respect to operations performed by a computing device, with the understanding that such a computing device may comprise any number devices programmed for operation of any and/or all of the steps of method  200 . The described computing device may comprise, for example, client device  120 , remote server  130 , compliance server  140 , and/or physical access point  150 . Ways to implement the stages of method  200  will be described in greater detail below. Method  200  may begin at stage  205  where a computing device may identify one and/or more items available for delivery. For example, remote server  130  may identify food and/or beverage items available for delivery to customers in a restaurant or bar, or a number of packages and mail items available for delivery to recipients within an office complex. Other scenarios in which method  200  may be employed comprise, for example, pickup and delivery of inventory items within a warehouse or multi-building storage complex and/or delivery of items around a geographic area, such as a city. 
     In some embodiments, the identified items may be selected based on factors such as known methods of transport, a priority for the available items and/or a known limit on the number of items that may be transported at a given time. For example, the number of items identified may be limited to the number of items able to be carried on a restaurant server&#39;s tray or on an office mail cart. 
     In some embodiments, the items available for delivery may be associated with multiple origination locations. For example, mail delivery items may originate from locations such as a mail sorting room, a loading dock, and a reception desk. Restaurant items may originate from a bar, a serving pass, multiple kitchens, hot or cold storage areas, etc. 
     In some embodiments, all items available for delivery within an environment may be identified at stage  205 . Characteristics for the items may also be identified, such as size, weight, time the item has been available, assigned delivery person or mechanism, etc. These characteristics may be maintained by the computing device based on inputs from users associated with preparing the items for delivery and/or may be scanned into the computing device based on labels, order tickets, RFID tags, or other data sources associated with the items for delivery. Collection of these characteristics may aid in prioritization, ordering, selection, and/or routing of the items in other stages of method  200 . 
     From stage  205 , method  200  may advance to stage  210  where the computing device may identify receiving locations for the items available for delivery. For example, at least some of the items available for delivery may be associated with recipients located within a particular geographic area. Such an association may comprise a predefined delivery location (e.g., a particular table in a restaurant or a cubicle within an office building) and/or the association may comprise an association with a mobile device. 
     In a use case for some embodiments of this disclosure, for example, a restaurant patron may place an order at a front counter or a bar. The order may be associated with a mobile device operative to provide its location to a delivery dispatch computing device such as that described with respect to method  200 . Such mobile devices may belong to the patron and/or may be provided by the restaurant. For example, the patron may register their cellular phone as a location identifier, using communication options built into the phone, such as wi-fi networking, near-field communications (NFC), radio frequency identifier tags (RFID), and/or Bluetooth. In some embodiments, the restaurant may issue a locatable mobile device, such as a pager, tablet, Bluetooth, NFC, or RFID tag, or other mobile device. The restaurant may provide receivers, such as wi-fi routers and NFC or RFID readers, around the geographic area for tracking the locations and movements of the locatable mobile devices. Such an arrangement may be similarly applied to other use cases, such as by using employees&#39; devices to track their current locations within an office complex or campus. 
     From stage  210 , method  200  may advance to stage  215  where the computing device may identify a delivery route. For example, a number of orders may be available for delivery from the kitchen to various tables within a restaurant. An optimized route from the kitchen to each of the table delivery locations may be computed according to various algorithms. The optimized route may take account of factors such as whether the delivery locations are on different floors, such that all items to be delivered on a first floor are routed to before items on another floor. 
     From stage  215 , method  200  may advance to stage  220  where the computing device may retrieve access credentials needed for the optimized delivery route. For example, remote server  130  may determine whether the identified route will require passage through physical access point  150 . If so, remote server  130  may associate physical access credentials  134  with the identified route. In various embodiments, the criteria for optimization of the delivery route may be different. For example, in some embodiments, optimization may refer to minimizing the time it takes to deliver the items and/or to delivering the items in a prioritized order. For example, a restaurant order item that has been waiting the longest may be prioritized and the route optimized to deliver that item first even if other delivery locations are physically closer. 
     From stage  220 , method  200  may advance to stage  225  where the computing device may provide the route (and access credentials, if needed) to the delivery person and/or mechanism. For example, the route and credentials may be provided to a tablet and/or other GPS-type device associated with the user who will be performing the delivery of the items. In some embodiments, the route and credentials may be provided to an automated delivery mechanism, such as an un-manned forklift operating in a warehouse. For a person, the route may be displayed on a screen associated with the device; for an automated mechanism, such a display may be unnecessary. 
     From stage  225 , method  200  may advance to stage  230  where the computing device may determine whether the delivery location for any of the items on the optimized route has changed. For example, the mobile devices associated with recipients of the items may be determined to have moved, such as when restaurant patrons are moving between tables or mingling in a bar area. Similarly, employees in an office complex may move between work areas, offices, labs, conference rooms, etc. In some embodiments, a delivery location may be changed by remote server  130  in response to a user input (e.g., changing of the delivery location identifier from one location to another, regardless of where the recipient is). 
     If the delivery location is determined to have changed at stage  230 , method  200  may advance to stage  235  where the computing device may update the optimized route. For example, the route may display directions to the new delivery location. In some embodiments, this may result in a re-ordering of the delivery items, such as where a delivery location for a first item is determined to now be further away than a delivery location of a second item. 
     After updating the route at stage  235 , or if no updates were determined to be required at stage  230 , method  200  may advance to stage  240  where the computing device may update a current position of the delivery person and/or mechanism. For example, a waiter may have delivered two of the restaurant order items; the waiter&#39;s current location may be identified and the optimized route to the next delivery location may be displayed. 
       FIGS.  3 A- 3 B  illustrate an example use case for item delivery optimization in accordance with method  200 . The example use case is illustrated in  FIG.  3 A  with respect to a restaurant floorplan  300  comprising a plurality of tables  305 (A)-(F), a waiter  310 , a plurality of restaurant patrons  315 (A)-(G), a bar  320 , and a plurality of wireless beacons  330 (A)-(C). Waiter  310  may be notified that items are available for delivery at the bar  320 . A route  325  may be identified and displayed on client device  120  carried by waiter  310 . 
       FIG.  3 B  illustrates an updated route in accordance with stage  240  of method  200 . For example, in  FIG.  3 B , restaurant patron  315 (G) has moved before receiving their order from waiter  310 . An updated route  350  is identified and provided to waiter  310  such that restaurant patron  315 (G) will receive their ordered item at their new location at table  305 (F). Similarly, restaurant patron  315 (C) is determined to be moving, and the delivery location for the items associated with restaurant patron  315 (C) has been updated. 
     Although the above figure illustrates a restaurant order delivery use case, this should be considered a non-limiting example. Many other uses have been contemplated, such as mail/parcel delivery, personnel location, emergency services aid, logistics tracking, equipment deployments, and others. For example, mail items for delivery to various persons within an office building may be routed and prioritized as described above, with routing instructions taking elevator availability and speeds into account. For the personnel location use case, mobile devices associated with a specified group of individuals could be tracked and a route to locate each and/or some of those individuals could be calculated. This may be particularly useful in a security application (e.g., tracking each member of a delegation or family) and/or in an educational setting (e.g., tracking the location of pre-schoolers and alerting a teacher when one is wandering out of bounds, then displaying a route to the child or helping chaperones locate their students while on a field trip). 
     In emergency situations, such as a fire, routes to people who may be trapped could be displayed, and/or routes to pre-defined rescue points and special needs people and/or their pets could be calculated. By relying on reports made by mobile devices associated with those who need assistance, emergency workers may receive additional information about the situation surrounding each, and routing priorities may be calculated accordingly. The mobile devices may receive inputs actively from users and/or may use sensors such as microphones and cameras to passively record and report the environment. Such passive recordings may also assist in determining which devices are actually associated with a user in need of assistance and which are simply in the area but not with a person. 
     Logistics tracking and equipment deployment cases may allow shippers and/or deployment managers to track and verify that multiple components of a shipment or deployment are on schedule, routed and/or deployed to the correct destinations, and properly prioritized. For example, a new wireless network deployment may specify a delivery location for a central Internet router and then a route to each of several repeater locations. 
       FIG.  4    illustrates schematic block diagram  400  of the remote server  130  and the client device  140  according to embodiments of the present disclosure. The remote server  130  includes at least one processor circuit, for example, having a processor  403  and a memory  406 , both of which are coupled to a local interface  409 . To this end, the remote server  130  may comprise, for example, at least one server computer and/or like device. Similarly, the client device  140  includes at least one processor circuit, for example, having a processor  413  and a memory  416 , both of which are coupled to a local interface  419 . Additionally, the client device  120  may be in data communication with a display for rendering user interfaces and at least one other I/O device for inputting and outputting data. To this end, the client device  140  may comprise, for example, at least one mobile wireless device, computer, and/or like device. The local interfaces  409  and  419  may comprise, for example, a data bus with an accompanying address/control bus and/or other bus structure as can be appreciated. 
     Stored in the memories  406  and  416  are both data and several components that are executable by the processors  403  and  413 . In particular, stored in the memory  406 / 416  and executable by the processors  403  and  413  are a authentication service  135 , an enterprise access application  124 , and potentially other applications. Also stored in the memories  406  and  416  may be a data stores  131  and  418  and other data. In addition, an operating system may be stored in the memories  406  and  416  and executable by the processors  403  and  413 . 
     It is to be understood that there may be other applications that are stored in the memories  406  and  416  and are executable by the processors  403  and  413  as can be appreciated. Where any component discussed herein is implemented in the form of software, any one of a number of programming languages may be employed such as, for example, C, C++, C#, Objective C, Java, Javascript, Perl, PHP, Visual Basic, Python, Ruby, Delphi, Flash, and/or other programming languages. 
     A number of software components are stored in the memories  406  and  416  and are executable by the processors  403  and  413 . In this respect, the term “executable” means a program file that is in a form that can ultimately be run by the processors  403  and  413 . Examples of executable programs may be, for example, a compiled program that can be translated into machine code in a format that can be loaded into a random access portion of the memories  406  and  416  and run by the processors  403  and  413 , source code that may be expressed in proper format such as object code that is capable of being loaded into a random access portion of the memory  406 / 416  and executed by the processors  403  and  413 , and/or source code that may be interpreted by another executable program to generate instructions in a random access portion of the memories  406  and  416  to be executed by the processors  403  and  413 , etc. An executable program may be stored in any portion and/or component of the memories  406  and  416  including, for example, random access memory (RAM), read-only memory (ROM), hard drive, solid-state drive, USB flash drive, memory card, optical disc such as compact disc (CD) and/or digital versatile disc (DVD), floppy disk, magnetic tape, and/or other memory components. 
     The memories  406  and  416  is defined herein as including both volatile and nonvolatile memory and data storage components. Volatile components are those that do not retain data values upon loss of power. Nonvolatile components are those that retain data upon a loss of power.

     Also, the processors  403  and  413  may represent multiple processors, and the memories  406  and  416  may represent multiple memories that operate in parallel processing circuits, respectively. In such a case, the local interfaces  409  and  419  may be an appropriate network  109  ( FIG.  1   ) that facilitates communication between any two of the multiple processors  403  and  413 , and/or between any two of the memories  406  and  416 , etc. The local interfaces  409  and  419  may comprise additional systems designed to coordinate this communication, including, for example, performing load balancing. The processors  403  and  413  may be of electrical and/or of some other available construction.
