Abstract:
Upon detection of a failure of a communication link between a remote management system and a communication node, a bypass link is established. The remote management system evaluates whether additional communication nodes can act as a bypass for management communications between the remote management system and the communication node whose management communication link has failed. The remote management system instructs a selected bypass communication node to establish the bypass management communication link between the bypass node and the disconnected node whose management communication link has failed. Depending on the relationship between nodes, management communications sent using the bypass link may be secured. The bypass link in some implementations may include multiple bypass communication nodes linked together to provide a chain of bypass management communication links between the remote management system and the disconnected communication node.

Description:
RELATED APPLICATIONS 
       [0001]    This application hereby claims the benefit of and priority to U.S. Provisional Patent Application 62/232,659, entitled “DENIED CONNECTIVITY AVAILABILITY FOR WEARABLE GROUP COMMUNICATION DEVICES,” filed Sep. 25, 2015, and which is hereby incorporated by reference in its entirety. 
     
    
     TECHNICAL FIELD 
       [0002]    Aspects of the disclosure are related to the field of communications and, in particular, to bypass connectivity for group communications. 
       TECHNICAL BACKGROUND 
       [0003]    Various communication devices can be employed to facilitate communication between users. These devices can include cellular telephones, smartphones, discrete devices, computers, and tablets, among others, which provide an efficient way for users to communicate without being in the same physical location. Often it is desirable to group these communication devices together so that multiple users may easily communicate with each other while excluding from the group those not involved in the discussion. However, due to the limited nature of wireless communications, it is possible for one or more devices within one or more groups to lose contact with each other or with centralized management systems, which may result in lost communications for those devices. 
       OVERVIEW BACKGROUND 
       [0004]    When a communication link fails between a remote management system and a communication node in a group communication system, a bypass communication link is established. When the link failure is detected, the remote management system can evaluate whether one or more additional communication nodes are available that can act as a bypass for management communications between the remote management system and the communication node whose management communication link has failed. After selecting a bypass communication node, the remote management system instructs the bypass communication node to establish a bypass management communication link between the bypass node and the node whose management communication link has failed. 
         [0005]    If the original communication node and the bypass node are in the same communication group or are otherwise affiliated, management communications may be sent as usual. If the bypass communication node is outside a communication group to which the original communication node belongs, then the management communications sent using the bypass link may be secured (e.g., through encryption). Moreover, the bypass link in some implementations may include multiple bypass communication nodes linked together to provide a chain of bypass management communication links.

     DETAILED DESCRIPTION 
       [0013]    In the examples below, personal communication nodes are discussed which allow group communication sessions among various users. These personal communication nodes can include discrete devices specialized for group communications that include one or more wireless transceivers and user interface elements tailored to streamlined group communications. The group communications can be initiated and altered by user intervention and/or automatically by a shared remote management system which can respond to one or more dynamic factors to form or change groups or group status. In some examples, one or more features of the discrete devices can be incorporated into other devices, such as personal communication devices which comprise cellular smartphones, gaming devices, personal computers, tablet computers, and the like. Voice command features can be included that comprise group forming and alteration features, keyword-based searching, productivity assistance, or navigation assistance, among other features. Further features can include conversational interaction for information transmittal or retrieval, such as activity reminders, weather, stocks, messaging, email, calendar, contacts, notes, music, clocks, web browsers, maps and other applications. 
         [0014]    Once a group has been formed, communication nodes that are members of the group may exchange secure communications with each other while maintaining communication (e.g., via wireless and/or other connectivity) with a remote management system that configures and controls the group. However, if a member node loses communication and/or connectivity with the remote management system, that management system may no longer be able to update group configurations and/or provide other services. In order to prevent the disconnected member node from losing its functionality, bypass connectivity communication with the remote management system is provided securely, either through other member nodes within the group or through non-member nodes. 
         [0015]    In a first non-limiting example,  FIG. 1  illustrates communication system  100 , which can be employed to provide intelligent agent features for communication nodes  102 - 105 . System  100  includes communication nodes  102 - 105 , and remote management system  150 . Communication nodes  102 - 105  typically operate in groups, such as Group A  110  and Group B  120  for example. These groups are defined by remote management system  150  (e.g., based on dynamic attributes communicated to remote management system  150  from communication nodes  102 - 105  or monitored by remote management system  150 , or based on node user inputs). Group A  110  and Group B  120  can each comprise a nexus of specified communication nodes  102 - 105  for interactive communications, information sharing, data exchange, and other mutual exchange. 
         [0016]    Communication nodes  102 - 105  may each comprise transceivers, audio transducers, processing systems, communication interfaces, environmental sensors, accelerometers, gyroscopes, Global Positioning System (GPS) receivers, user interfaces, and other systems. Remote management system  150  may comprise a computing system comprising one or more computing devices capable of managing services to a plurality of communication nodes, such as communication nodes  102 - 105 . 
         [0017]    Communication nodes  102 - 105  communicate with each other or with other communication nodes or intelligent agents over associated links  131 - 134 . Communication links  131 - 134  can be used to connect communication nodes  102 - 105  to each other and/or to other personal communication nodes. In some examples, links  131 - 134  may comprise a mesh network among communication nodes  102 - 105 . Communication nodes  102 - 105  can also communicate with remote management system  150  over associated ones of management communication links  141 - 144 , which can comprise one or more network links in this example. Management communication links  141 - 144  connect communication nodes  102 - 105  to remote management system  150 . 
         [0018]    Links  131 - 134  and  141 - 144  can each comprise one or more wireless links that can each further include Long Term Evolution (LTE), Global System For Mobile Communications (GSM), Code Division Multiple Access (CDMA), IEEE 802.11 WiFi, Bluetooth, Personal Area Networks (PANs), Wide Area Networks, (WANs), Local Area Networks (LANs), or Wireless Local Area Networks (WLANs), including combinations, variations, and improvements thereof. These links can carry any communication protocol suitable for wireless communications, such as Internet Protocol (IP) or Ethernet. 
         [0019]    Furthermore, links  131 - 134  can comprise Bluetooth, IEEE 802.11 WiFi, infrared, ultrasonic, or any wireless communication format including combinations, variations or improvements thereof. Communication links  131 - 134  can each use air or space as the transport media. Additionally, links  141 - 144  can include one or more wired portions which can comprise synchronous optical networking (SONET), hybrid fiber-coax (HFC), Time Division Multiplex (TDM), asynchronous transfer mode (ATM), circuit-switched, communication signaling, or some other communication signaling, including combinations, variations or improvements thereof. Communication links  141 - 144  can each use metal, glass, optical, air, space, or some other material as the transport media. Communication links  131 - 134  and  141 - 144  may each be a direct link, or may include intermediate networks, systems, or devices, and may include a logical network link transported over multiple physical links. 
         [0020]    In  FIG. 1 , each communication node  102 - 105  monitors one or more attributes from associated positional sensors, audio transducers, GPS receivers, accelerometers, wireless transceivers, environmental sensors, or other sensors or devices capable of monitoring the attributes discussed herein. These attributes comprise any data or information that may be used for dynamically forming and changing node groups, as well as for intelligent agent features for communication nodes  102 - 105 . For example, one or more of the sound level of an environment, user preferences, proximity of one personal communication node to another, location, communication status, identity, and traveling speed may be attributes used for dynamically forming and changing groups of nodes as well as for intelligent agent features for communication nodes  102 - 105 . 
         [0021]    Communication nodes  102 - 105  periodically transfer messages for delivery to remote management system  150  (e.g., indicating dynamic changes in one or more attributes, user inputs, and/or other data useful in managing a node or a group). Communication nodes  102 - 105  may transfer a message to remote management system  150  whenever an attribute changes and/or at periodic intervals. Remote management system  150  can use dynamic changes in one or more attributes to form, modify and/or terminate groups of communication nodes  102 - 105  and for intelligent agent features for communication nodes  102 - 105 . Although remote management system  150  and nodes  102 - 105  are each shown as separate entities in  FIG. 1 , it should be understood that features of remote management system  150  can be included in any of personal communication nodes  102 - 105 . 
         [0022]    A communication node may use secure communication methods for communicating with members of a communication group, with non-members and/or with a remote management system or the like. Secure communication methods include systems, techniques, protocols, methods and other approaches enabling users and nodes to securely share communications and other information with one another without interception or monitoring of the information or associated communications by non-members and/or third-party. Secure communication methods may comprise symmetric key encryption, asymmetric key encryption, public-key encryption, or some other type of encryption, including combinations thereof. The actual communications between personal communication nodes can employ secure communication methods, and the associated links can employ secure communication methods independently. 
         [0023]    End to end encryption of communications, such as audio communications, can be established among members of the group. These end-to-end encrypted communications can include transport layer security (TLS) or secure sockets layer (SSL) communications, among other secure link types. For example, a secure communication session can be established among nodes  102 - 105  in Group B  120  of  FIG. 1 , as well as among nodes  102 - 104  in Group A  110 . 
         [0024]      FIG. 2  illustrates communication system  100  of  FIG. 1 , where management communication link  141  between node  102  and remote management system  150  has been disrupted or has failed (step (A)). The disruption can occur in wireless communications due to many factors, such as overloading of wireless network equipment, wireless signal fading, out-of-range conditions, weather, structures, movement, or other factors, including combinations thereof. In this example, remote management system  150  determines (step (B)) which communication node(s) can act as a bypass for the failed management communication link. Remote management system  150  identifies and communicates with node  103  (step (C)) and instructs node  103  to initiate management communications link  200  with node  102 , where communication link  200  functions as a failover bypass of failed link  141 . Node  103  then acts (step (D)) to relay communications between node  102  and remote management system  150  through bypass communication links  200  and  142 . Since communication node  102  is in the same group (Group A  110 ) as communication node  103 , there may be no security risk in having communication node  103  relay group-related communications between communication node  102  and remote management system  150 . 
         [0025]      FIG. 3  illustrates communication system  100  as shown in  FIG. 1 , where all of Group A  110 &#39;S management communication links (i e , management communication link  141  between communication node  102  and remote management system  150 , management communication link  142  between communication node  103  and remote management system  150 , and management communication link  143  between communication node  104  and remote management system  150 ) have been disrupted or have failed. In this example, remote management system  150  thus has lost contact with all members of Group A  110 . 
         [0026]    Since remote management system  150  still maintains one or more management communication links with communication nodes of other groups (e.g., Group B  120 &#39;s communication node  105  through management communication link  144 ), remote management system  150  is able to instruct communication node  105  to configure a bypass to make contact with one or more of the communication nodes  102 - 104  in Group A  110  to resume management contact with Group A  110 . Here, remote management system  150  instructs communication node  105  to open management communication link  300  to communication node  104 . Management communication link  300  can be encrypted so that communication node  105  is unable to decode communications between node  104  and remote management system  150 . Remote management system  150  is thus able to communicate with node  104  via non-member bypass management link  300  and instruct node  104  to open member bypass management communication link  301  with node  103 . Remote management system  150  is then able to communicate with communication node  103  and instruct node  103  to open member bypass management communication link  302  with node  102 . In other examples, communication node  104  may open communication links with both node  103  and node  102  so that node  103  is not required to forward communications from node  102  to node  104 . 
         [0027]      FIG. 4  illustrates one or more implementations of a remote management system  400 . System  400  is a non-limiting example (e.g., of a computing environment that can execute features of remote management system  150  of  FIG. 1  and/or remote management systems discussed herein). Furthermore, elements of remote management system  400  can be distributed over one or more computing devices (including one or more communication nodes). Remote management system  400  includes processing circuitry  401 , storage system  402 , software  403 , communication interface system  407 , and user interface system  408 . 
         [0028]    It may be understood that remote management system  400  is generally intended to represent one or more computing systems on which software  403  may be deployed and executed (e.g., in order to implement remote management system  150 ). However, remote management system  400  may also be suitable as any computing system on which software  403  may be staged and from where one or both may be distributed, transported, downloaded, or otherwise provided to yet another computing system for deployment and execution, or yet additional distribution. 
         [0029]    Communication interface system  407  may include communication connections and devices that allow for communication with other computing systems over a communication network. Examples of connections and devices that together allow for inter-system communication may include network interface cards, antennas, power amplifiers, RF circuitry, transceivers, and other communication circuitry. The connections and devices may communicate over communication media to exchange communications with other computing systems or networks of systems, such as metal, glass, air, or any other suitable communication media. 
         [0030]    User interface system  408  may include a keyboard, a mouse, a voice input device, a touch input device for receiving a touch gesture from a user, a motion input device for detecting non-touch gestures and other motions by a user, and other comparable input devices and associated processing elements capable of receiving user input from a user. Output devices such as a display, speakers, haptic devices, and other types of output devices may also be included in user interface system  408 . In some cases, the input and output devices may be combined in a single device, such as a display capable of displaying images and receiving touch gestures. 
         [0031]    User interface system  408  may also include associated user interface software executable by processing circuitry  401  in support of the various user input and output devices discussed above. Separately or in conjunction with each other and other hardware and software elements, the user interface software and user interface devices may support a graphical user interface, a natural user interface, or any other type of user interface. In addition, user input made with respect to the user interfaces may be input via user interface system  408 . 
         [0032]    Communication between remote management system  400  and any other computing system may occur over a communication network or networks and in accordance with various communication protocols, combinations of protocols, or variations thereof. Examples of such communication networks include intranets, internets, the Internet, local area networks, wide area networks, wireless networks, wired networks, virtual networks, software defined networks, data center buses, computing backplanes, or any other type of network, combination of network, or variation thereof. Some communication protocols that may be used include, but are not limited to, the Internet protocol (IP, IPv4, IPv6), the transfer control protocol (TCP), and the user datagram protocol (UDP), as well as any other suitable communication protocol, variation, or combination thereof. 
         [0033]    Processing circuitry  401  can comprise one or more microprocessors and other processing circuitry that retrieves and executes software  403  from storage system  402 . Processing circuitry  401  can be implemented within a single processing device but can also be distributed across multiple processing devices or sub-systems that cooperate in executing program instructions. Examples of processing circuitry  401  include general purpose central processing units, application specific processors, and logic devices, as well as any other type of processing device, combinations, or variations thereof. In some examples, portions of processing circuitry  401  is physically separate from some elements of remote management system  400  and area included in remote servers, cloud-based processing systems, or virtualized computing systems. 
         [0034]    Storage system  402  can comprise any non-transitory computer readable storage media capable of storing software  403  that is executable by processing circuitry  401 . Storage system  402  can also include various data structures which comprise one or more databases, tables, lists, or other data structures. Storage system  402  can include volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information, such as computer readable instructions, data structures, program modules, or other data. Storage system  402  can be implemented as a single storage device but can also be implemented across multiple storage devices or sub-systems co-located or distributed relative to each other. Storage system  402  can comprise additional elements, such as a controller, capable of communicating with processing circuitry  401 . Examples of storage media include random access memory, read only memory, magnetic disks, optical disks, flash memory, virtual memory and non-virtual memory, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to store the desired information and that can be accessed by an instruction execution system, as well as any combination or variation thereof. 
         [0035]    Software  403  can be implemented in program instructions and among other functions can, when executed by remote management system  400  in general or processing circuitry  401  in particular, direct remote management system  400 , or processing circuitry  401  to operate as described herein for a remote management system or other functional systems. Software  403  can include additional processes, programs, or components, such as operating system software, database software, or application software. Software  403  can also comprise firmware or some other form of machine-readable processing instructions executable by elements of processing circuitry  401 . 
         [0036]    In at least one implementation, the program instructions can include attributes module  404 , group module  405 , and security module  406 . Attributes module  404  monitors one or more attributes of communication nodes (e.g., transferring messages for delivery to a management system indicating dynamic changes in one or more attributes). These attributes and dynamic changes in attributes can be used to form and change dynamic communication groups among communication nodes and intelligent agent nodes. Attributes module  404  may periodically or continuously monitor attributes associated with communication node sensors or communication nodes may send messaging or alerts to attributes module  404  when changes are detected. Attributes module  404  receives attributes (e.g., from communication nodes  102 - 105 ) and transmits attributes (e.g., to communication nodes  102 - 105  over management communication links  141 - 144 ). 
         [0037]    Group module  405  monitors group membership status among communication nodes, and changes the group membership of communication nodes (e.g., based on the attributes and the group membership status). Group module  405  further monitors management communication links (e.g., between remote management system  150  and associated communication nodes  102 - 105  in implementations such as the one shown in  FIG. 1 ). When a management communication link failure is detected, group module  405  determines an identity of a bypass communication node that can be used to communicate with communication nodes that have been disconnected due to the management communication link failure. Group module  405  then directs the bypass communication node to establish a management communication link with the communication node that has experienced the communication link failure. This enables the bypass communication node to forward management communications between remote management system  400  and the communication node experiencing the communication link failure. 
         [0038]    Security module  406  initiates, controls, and maintains secure communications between remote management system  400  and associated communication nodes, and among communication nodes. For example, when group module  405  identifies a bypass communication node that is external to a group of communication nodes whose management communication links with remote management system  400  have failed, security module  406  establishes secure communication links through the bypass communication node between management system  400  and the group of disconnected communication nodes. This enables the bypass communication node to act as a conduit to forward communications between the remote management system  400  and the other group of communication nodes without having the ability to decode the communications. 
         [0039]    In general, software  403  can, when loaded into processing circuitry  401  and executed, transform processing circuitry  401  overall from a general-purpose computing system into a special-purpose computing system customized to operate as described herein for a remote management system, among other operations. Encoding software  403  on storage system  402  can transform the physical structure of storage system  402 . The specific transformation of the physical structure can depend on various factors in different implementations of this description. Examples of such factors can include, but are not limited to the technology used to implement the storage media of storage system  402  and whether the computer-storage media are characterized as primary or secondary storage. For example, if the computer-storage media are implemented as semiconductor-based memory, software  403  can transform the physical state of the semiconductor memory when the program is encoded therein. For example, software  403  can transform the state of transistors, capacitors, or other discrete circuit elements constituting the semiconductor memory. A similar transformation can occur with respect to magnetic or optical media. Other transformations of physical media are possible without departing from the scope of the present description, with the foregoing examples provided only to facilitate this discussion. 
         [0040]      FIG. 5  illustrates a method for operating a remote management system (e.g., remote management system  150  as illustrated in one or more of the Figures). A remote management system detects a failure in a first management communication link used for communications between a first communication node and the remote management system (operation  500 ). The remote management system then determines that one or more additional communication nodes are capable of acting as a bypass communication node and identifies a second communication node as such (operation  502 ). 
         [0041]    The remote management system transmits instructions to establish a bypass management communication link with the first communication node (operation  504 ) and subsequently communicates with the first node through the bypass management communication link (e.g., as shown with link  200  of  FIG. 2 ), the second (bypass) communication node (e.g., node  103  of  FIG. 2 ), and the second node&#39;s communication link (e.g., link  142  of  FIG. 2 ) with the remote management system (operation  506 ). Operation  504  can be performed by having the second (bypass) communication node set up the bypass management communication link directly with the first communication node. In other implementations the bypass instructions may include the second node establishing a bypass management communication link with a third communication node and that third node establishing an additional bypass management communication link with the first communication node (directly or through one or more additional communication nodes acting as bypass nodes), creating a multiple bypass node chain somewhat similar to the implementation(s) shown in  FIG. 3 . 
         [0042]      FIG. 6  illustrates one or more implementations of a communication node  600 . Communication node  600  is a non-limiting example (e.g., of a computing environment that can execute features of communication nodes  102 - 105  of  FIG. 1  and/or communication nodes discussed herein). Furthermore, elements of communication node  600  can be distributed over one or more computing devices. Communication node  600  includes processing circuitry  601 , storage system  602 , software  603 , communication interface system  607 , and user interface system  608 . 
         [0043]    It may be understood that communication node  600  is generally intended to represent one or more computing systems on which software  603  may be deployed and executed (e.g., in order to implement communication nodes  102 - 105 ). However, communication node  600  may also be suitable as any computing system on which software  603  may be staged and from where one or both may be distributed, transported, downloaded, or otherwise provided to yet another computing system for deployment and execution, or yet additional distribution. 
         [0044]    In this example, wireless communication device  610  is shown separate and independent from communication node  600 . Wireless communication device  610  may comprise a smartphone, tablet device, computer, gaming device, laptop computer, or some other communication device capable of communicating using packet networks or some other communication network. In another example, communication node  600  may be incorporated as software within wireless communication device  610 . In other examples communication node  600  may be a discrete node that communicates through wireless communication device  610  such as a Bluetooth device to a smartphone and cellular service from the smartphone to other communication nodes and remote management system  150 . 
         [0045]    Communication interface system  607  may include communication connections and devices that allow for communication with other computing systems over a communication network. Examples of connections and devices that together allow for inter-system communication may include network interface cards, antennas, power amplifiers, RF circuitry, transceivers, and other communication circuitry. The connections and devices may communicate over communication media to exchange communications with other computing systems or networks of systems, such as metal, glass, air, or any other suitable communication media. 
         [0046]    Communication interface system  607  further comprises transceiver  609  for communicating with wireless communication device  610 . Transceiver  609  comprises communication components, such as ports, signal processing circuitry, memory, software, and the like. Transceiver  609  communicates with wireless communication device  610  over a link that may comprise a Bluetooth communication link, WiFi link, infrared, ultrasonic or any other communication link between communication node  600  and wireless communication device  610 . 
         [0047]    User interface system  608  may include a keyboard, a mouse, a voice input device, a touch input device for receiving a touch gesture from a user, a motion input device for detecting non-touch gestures and other motions by a user, and other comparable input devices and associated processing elements capable of receiving user input from a user. Output devices such as a display, speakers, haptic devices, and other types of output devices may also be included in user interface system  608 . In some cases, the input and output devices may be combined in a single device, such as a display capable of displaying images and receiving touch gestures. 
         [0048]    User interface system  608  may also include associated user interface software executable by processing circuitry  601  in support of the various user input and output devices discussed above. In communication node  600 , user interface system  608  is optional as some embodiments of communication node  600  do not require any user interaction. Separately or in conjunction with each other and other hardware and software elements, the user interface software and user interface devices may support a graphical user interface, a natural user interface, or any other type of user interface. In addition, user input made with respect to the user interfaces may be input via user interface system  608 . 
         [0049]    Communication between communication node  600  and any other computing system may occur over a communication network or networks and in accordance with various communication protocols, combinations of protocols, or variations thereof. Examples of such communication networks include intranets, internets, the Internet, local area networks, wide area networks, wireless networks, wired networks, virtual networks, software defined networks, data center buses, computing backplanes, or any other type of network, combination of network, or variation thereof. Some communication protocols that may be used include, but are not limited to, the Internet protocol (IP, IPv4, IPv6), the transfer control protocol (TCP), and the user datagram protocol (UDP), as well as any other suitable communication protocol, variation, or combination thereof. 
         [0050]    Processing circuitry  601  can comprise one or more microprocessors and other processing circuitry that retrieves and executes software  603  from storage system  602 . Processing circuitry  601  can be implemented within a single processing device but can also be distributed across multiple processing devices or sub-systems that cooperate in executing program instructions. Examples of processing circuitry  601  include general purpose central processing units, application specific processors, and logic devices, as well as any other type of processing device, combinations, or variations thereof. In some examples, portions of processing circuitry  601  is physically separate from some elements of communication node  600  and area included in remote servers, cloud-based processing systems, or virtualized computing systems. 
         [0051]    Storage system  602  can comprise any non-transitory computer readable storage media capable of storing software  603  that is executable by processing circuitry  601 . Storage system  602  can also include various data structures which comprise one or more databases, tables, lists, or other data structures. Storage system  602  can include volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information, such as computer readable instructions, data structures, program modules, or other data. Storage system  602  can be implemented as a single storage device but can also be implemented across multiple storage devices or sub-systems co-located or distributed relative to each other. Storage system  602  can comprise additional elements, such as a controller, capable of communicating with processing circuitry  601 . Examples of storage media include random access memory, read only memory, magnetic disks, optical disks, flash memory, virtual memory and non-virtual memory, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to store the desired information and that can be accessed by an instruction execution system, as well as any combination or variation thereof. 
         [0052]    Software  603  can be implemented in program instructions and among other functions can, when executed by communication node  600  in general or processing circuitry  601  in particular, direct communication node  600 , or processing circuitry  601  to operate as described herein for a communication node among other functional systems. Software  603  can include additional processes, programs, or components, such as operating system software, database software, or application software. Software  603  can also comprise firmware or some other form of machine-readable processing instructions executable by elements of processing circuitry  601 . 
         [0053]    In at least one implementation, the program instructions can include attributes module  604 , group module  605 , and security module  606 . Attributes module  604  monitors one or more attributes of communication nodes (e.g., transferring messages for delivery to a remote management system (e.g., system  150 ) indicating dynamic changes in one or more attributes). These attributes and dynamic changes in attributes can be used to form and change dynamic communication groups among communication nodes and intelligent agent nodes. Attributes module  604  may periodically or continuously monitor attributes associated with communication node sensors or communication nodes may send messaging or alerts to attributes module  604  when changes are detected. Attributes module  604  receives attributes (e.g., from remote management system  150 ) and transmits attributes (e.g.) to remote management system  150  over management communication links  141 - 144 ). 
         [0054]    Group module  605  monitors group membership status among communication nodes, and changes the group membership of communication nodes (e.g., based on the attributes and the group membership status). Group module  605  further receives instructions (e.g., from remote management system  150 ) related to groups in which it is a member. In one non-limiting example, remote management system  150  detects a management communication link failure and determines an identity of a bypass communication node (e.g., from one or more nodes capable of acting as a bypass node) that may be used to communicate with communication nodes that have been disconnected due to the management communication link failure. Group module  605  then receives direction from the remote management system directing the communication node to operate as a bypass management communication node and to establish a management communication link with the communication node that has experienced the communication link failure. This enables the bypass communication node to act as a conduit to forward communications between a remote management system and the communication node experiencing the communication link failure. 
         [0055]    Security module  606  initiates, controls, and maintains secure communications between communication node  600  and other communication nodes  102 - 105  (e.g., management communications between node  600  and a remote management system). For example, when communication node  600  operates as a bypass communication node that is external to the group of communication nodes whose communication link(s) with a remote management system have failed, security module  606  establishes secure management communication links between the bypass communication node and any disconnected communication nodes. This enables the bypass communication node to forward management communications between the remote management system and the disconnected communication nodes without having the ability to decode the communications. 
         [0056]    In general, software  603  can, when loaded into processing circuitry  601  and executed, transform processing circuitry  601  overall from a general-purpose computing system into a special-purpose computing system customized to operate as described herein for a communication node and/or to perform other operations. Encoding software  603  on storage system  602  can transform the physical structure of storage system  602 . The specific transformation of the physical structure can depend on various factors in different implementations of this description. Examples of such factors can include, but are not limited to the technology used to implement the storage media of storage system  602  and whether the computer-storage media are characterized as primary or secondary storage. For example, if the computer-storage media are implemented as semiconductor-based memory, software  603  can transform the physical state of the semiconductor memory when the program is encoded therein. For example, software  603  can transform the state of transistors, capacitors, or other discrete circuit elements constituting the semiconductor memory. A similar transformation can occur with respect to magnetic or optical media. Other transformations of physical media are possible without departing from the scope of the present description, with the foregoing examples provided only to facilitate this discussion
