Description:
BACKGROUND 
       [0001]    With the proliferation of electronic computing and communication devices has come the need for such devices to communicate and exchange data. Traditional wired networks have addressed this need by enabling connected devices to communicate with the network and with each other. Wired networks are limited, however, in that a device must have a wire connection to the network in order to utilize the network to communicate and exchange data. Thus, a device may only connect to such a network at specific locations that have been provided with wire connections to the network. 
         [0002]    To address this limitation of traditional wired networks, the wireless network was developed. Wireless networks allow devices with wireless capability to connect to the network and to utilize the network to communicate and exchange data, without the requirement of a wire connection to the network. Instead, the connection to the wireless network is made via the transmission and reception of electromagnetic waves (e.g. radio waves and/or microwaves). 
         [0003]    The vast majority of wireless networks utilize some type of wireless access point (WAP) to enable wireless devices to connect to the network. In most instances, a WAP acts as a central hub to receive wireless transmissions from wireless devices and to connect the wireless devices to a traditional infrastructure wired network. While the use of WAPs is increasing, there are still many locations where, due to the physical limitations inherent in broadcasting and receiving radio waves, connection to a WAP is not possible. Further, there are instances where connection to a WAP is not desirable due to security concerns or the requirement of registering a device with a wireless network. Accordingly, there are instances and locations where connection to a network is not possible due to the absence of either a wired network or a satisfactory wireless network. 
         [0004]    Notwithstanding the inability in certain situations to connect to a traditional infrastructure network, wireless devices may utilize an independent basic service set (IBSS), also known as an ad hoc cell, to engage in wireless communication with each other. An IBSS allows devices with wireless capability to exchange wireless signals with other wireless devices, in the absence of a traditional WAP or infrastructure network. This is achieved through the creation of an ad hoc wireless cell. However, the setup of an IBSS is a complex process that requires the user to manually enter multiple operational parameters, including the assignment of IP addresses for devices that desire to associate with the IBSS. This complexity, combined with the network knowledge required to create an IBSS, has deterred potential users from utilizing this functionality.

     DETAILED DESCRIPTION 
       [0013]    In various embodiments described below, systems and methods are described for the simplified setup and administration of an independent basic service set (IBSS), also known as an ad hoc wireless cell (these terms are used interchangeably herein). By utilizing an IBSS, a wireless cell can be created in the absence of a traditional infrastructure network. Thus, by creating an IBSS cell, two or more wireless-enabled devices can communicate and exchange data with each other. A wireless-enabled device can include, by way of example and not limitation, a cell phone, a laptop, a portable digital assistant, or any other device capable of being configured to transmit and/or receive wireless signals. 
         [0014]    In some embodiments, the discussed systems and methods are based on the 802.11 wireless standards, which provide wireless local access network medium access control and physical layers specifications. See, e.g., ANSI/IEEE 802.11 standard, first edition  1999 , and its subsequent amendments. Thus, in some embodiments, the discussed systems and methods serve as additions to and expansions of the 802.11 standards. 
         [0015]    The discussion below will proceed as follows. First, an exemplary environment in which an IBSS cell may be utilized will be discussed. Following this, an exemplary IBSS cell creation wizard is discussed. Next, an exemplary method for creating an IBSS cell is presented. Following this, an exemplary method for joining an existing IBSS cell is discussed. Further, an exemplary method is presented for disconnecting from an IBSS cell and/or reassigning the IBSS cell initiator. Finally, an exemplary electronic system that can utilize an IBSS cell is discussed. 
         [0016]    Exemplary IBSS Environment 
         [0017]    With reference to  FIG. 1 , an exemplary environment in which an IBSS cell may be utilized is shown generally at  100 . In this example, a wireless-enabled initiator  102  creates an IBSS cell and begins advertising the cell by transmitting a signal  108  (e.g via radio waves) that may be detected by other wireless-enabled devices. Further to this example, wireless-enabled devices  104  and  106  are within reception range of the initiator&#39;s signal and thus are capable of detecting the signal. While the wireless-enabled devices used in this illustration are laptop computers, this is not intended to be limiting, and any suitable wireless-enabled device may be utilized to create and/or associate with an IBSS cell. 
         [0018]    The environment of  100  is shown generally at  110  and illustrates that wireless-enabled devices  104  and  106  have elected to associate with the IBSS cell, and thus communications link  112  has been established between wireless-enabled devices  102 ,  104  and  106 . In contradistinction to the standard access point architecture of a typical wireless infrastructure network, the creation of an IBSS cell results in a communications link between and among all of the associated cell members. Thus, with the establishment of communications link  112 , each of wireless-enabled devices  102 ,  104  and  106  are capable of sending data to and receiving data from each of the other members of the IBSS cell. While  FIG. 1  illustrates an IBSS cell comprising three wireless-enabled devices, this is not intended to be limiting, and an IBSS cell may contain any suitable number of wireless-enabled devices. 
         [0019]    Exemplary IBSS Cell Creation Wizard 
         [0020]    In  FIGS. 2-4 , interface screens from an exemplary IBSS cell creation wizard in accordance with one embodiment are illustrated. These examples are presented for purposes of illustration only and, according to various embodiments, an IBSS cell creation wizard may utilize any suitable configuration that permits the entry of IBSS cell specifications. 
         [0021]    In  FIG. 2 , an exemplary IBSS cell creation wizard introductory screen or user interface is shown at  200 . In some embodiments, screen  200  may be displayed in response to a user activating an IBSS cell creation wizard icon. However, this is not intended to be limiting, and screen  200  may be displayed according to other activation scenarios. An interface portion or field  202  prompts the user to enter a name for the IBSS cell. An interface portion or field  204  prompts the user to select a band or bands on which the IBSS cell will operate. The use of the band options “A+B” and “A+G” in this example refers to the bands utilized by the corresponding 802.11 wireless standards (i.e. the 802.11b, 802.11a, and 802.11g standards). The illustrated bands are used for purposes of example only, and other suitable bands that may be utilized are well known to those of skill in the art. 
         [0022]    In this example, an interface portion  206  in the form of a “next” button is displayed and allows the user to transition to a subsequent screen in the IBSS cell creation wizard. An interface portion  208  in the form of a “cancel” button is displayed and allows a user to cancel the creation of the IBSS cell and exit the wizard. 
         [0023]      FIG. 3  illustrates at  300  an exemplary intermediate screen or user interface of an IBSS cell creation wizard in accordance with one embodiment. An interface portion or field  302  prompts a user to select a security protocol or protocols under which the IBSS cell will operate. The example illustrated here presents the user with the security options of wired equivalent privacy (WEP) or media access control (MAC) address filtering. These security options are presented for purposes of illustration only, and other security techniques and protocols may be utilized without departing from the spirit and scope of the claimed subject matter. An interface portion or field  304  prompts the user to select an IP address assignment method. The selected method will be utilized to assign IP addresses to wireless-enabled devices that wish to join the IBSS cell. In this example, the IBSS cell creation wizard gives a user the option of choosing dynamic host configuration protocol (DHCP) or manual IP address assignment. However, the use of these examples is not meant to be limiting, and other suitable methods for allocating IP addresses may be employed within the spirit of the disclosed embodiments. 
         [0024]    An interface portion  306  in the form of a “back” button is displayed and, if actuated, allows a user to return to a previous wizard screen. An interface portion  308  in the form of a “next” button allows a user to transition to a subsequent screen in the IBSS cell creation wizard. Finally, an interface portion  310  in the form of a “cancel” button is provided and, if actuated, gives the user the option of canceling the creation of the IBSS cell and exiting the IBSS cell wizard. 
         [0025]      FIG. 4  presents at  400  an exemplary summary screen or user interface of an IBSS cell creation wizard in accordance with one embodiment. An interface portion  402  lists a summary of the IBSS cell specifications that may be used to create an IBSS cell. This summary may contain IBSS cell specifications that were selected or specified by the user, while other listed IBSS cell specifications may be default values that were not expressly specified by the user. The cell specifications listed in this example (e.g. cell name “Gromit”, cell band “A+G”, etc.) are for purposes of illustration only, and are not intended to be limiting. An interface portion  404  in the form of a “back” button is presented and allows a user to transition to a previous screen in the IBSS cell creation wizard. An interface portion  406  in the form of a “finish” button is presented and, if actuated, indicates that the user accepts the IBSS cell specifications and desires to create an IBSS cell based on these specifications. Finally, an interface portion  408  in the form of a “cancel” button gives a user the option of canceling the creation of the IBSS cell and exiting the IBSS cell creation wizard. 
         [0026]    The diagrams discussed above constitute but one example of a single user interface type that can be utilized to create an IBSS cell. It is to be appreciated that other user interface types can be used without departing from the spirit and scope of the described embodiments. 
         [0027]    Exemplary Methods 
         [0028]      FIG. 5  is a flow diagram that illustrates an exemplary method for creating an IBSS cell in accordance with one embodiment. The method can be implemented in connection with any suitable hardware, software, firmware or combination thereof. In at least some embodiments, the method is implemented in software in the form of computer-readable instructions that reside on a computer-readable medium. 
         [0029]    At  502 , a user initiates the creation of an IBSS cell. This act may be accomplished by pressing a corresponding icon displayed on the user&#39;s wireless-enabled device, or by any other suitable means for invoking such a method. In some embodiments, act  502  may cause a user interface to be displayed. At  504 , the user enters specifications that may be used, at least in part, to create the IBSS cell. In some embodiments, the specifications entered in act  504  may be input via a user interface. At act  506 , a summary of IBSS cell specifications is presented to the user. In some embodiments, this act may take the form of a list of IBSS cell specifications graphically displayed to the user. At  508 , the user is given the option of approving one or more IBSS cell specifications. If the user approves the proffered specifications, act  510  then creates or initiates the IBSS cell based at least in part on the approved specifications. Act  512  then begins advertising the IBSS cell by transmitting a beacon that includes, at least in part, an IBSS cell information element (CIE). A CIE is an information-containing data packet that, in some embodiments, allows other wireless-enabled devices to detect an available IBSS cell. In accordance with one embodiment, a CIE may have the following data fields:

         [0030]    The listing of these particular data fields is not intended to be limiting, and other CIEs may contain differing amounts and types of data fields. 
         [0031]    Referring back to act  508 , if a user indicates that the user does not approve the proffered specifications, act  514  then gives the user the option of reentering one or more IBSS cell specifications. If the user chooses to reenter the specification(s), the user is returned to act  504 . If the user chooses not to reenter the specification(s), act  516  terminates the creation of the IBSS cell and, in some embodiments, closes any open IBSS cell creation interface. 
         [0032]      FIG. 6  is a flow diagram that illustrates an exemplary method for associating with an IBSS cell in accordance with one embodiment. The method can be implemented in connection with any suitable hardware, software, firmware or combination thereof. In at least some embodiments, the method is implemented in software in the form of computer-readable instructions that reside on a computer-readable medium. 
         [0033]    At  602 , a wireless-enabled device scans for any available IBSS cell(s). In some embodiments, this scan may be periodic in nature or, in alternate embodiments, may consist of a continuous scan. Other modes of scanning may be employed without departing from the spirit and scope of the described embodiments. At  604 , the wireless-enabled device determines whether or not an available IBSS cell has been detected. If an available IBSS cell has not been detected, then the method returns to act  602  and continues scanning for available IBSS cells. While not expressly illustrated here, other embodiments may cease scanning for available IBSS cells after failing to detect an available IBSS cell at act  604 . 
         [0034]    If an available IBSS cell is detected at act  604 , then act  606  displays an indication of the available cell(s). Any suitable indication can be used. At  608 , the user is given the option of joining the IBSS cell. If the user indicates a desire not to join the IBSS cell, either expressly or impliedly, then, as indicated at  609 , the user is not associated with the cell. If the user desires to join the IBSS cell, then the user so indicates at act  610 . At act  612 , the user then sends an association request to the initiator of the IBSS cell. In some embodiments, the transmitted association request includes an association information element (AIE) that is sent to the initiator of the IBSS cell. The primary purpose of the AIE is to notify the initiator of the IBSS cell that a wireless-enabled device desires to associate with the IBSS cell. An exemplary AIE may contain the data fields listed below in table 2. However, the inclusion of this table is not intended to be limiting, and other AIEs may contain different amounts and types of data fields.

         [0035]    At  614 , the initiator receives the AIE and responds by sending a response information element (RIE) to the requesting device. The primary purpose of the RIE is to provide the requesting device with an IP address that will allow the requesting device to associate with the IBSS cell. If the initiator grants the association request, the RIE will contain a valid IP address. An exemplary RIE may contain the following data fields, as illustrated below in table 3. The data fields illustrated in table 3 are for purposes of example only, and other RIEs may contain different amounts and types of data fields.

         [0036]    In some embodiments, if the initiator does not grant the request, the RIE will contain a null IP address. In alternate embodiments, the initiator will simply not return an RIE, thereby preventing the requesting device from receiving and IP address from the initiator. If the initiator grants the association request and provides or assigns a valid IP address, the requesting device is associated with the cell at  616 . In some embodiments, act  616  may include transmitting to the initiator, by the associating device, a notification that the specific IP address provided by the initiator has been accepted by the requesting device and is being used by the requesting device to associate with the IBSS cell. After sending the RIE with the IP address, the initiator will update the IP list element in the beacon to indicate that the IP address is not currently available. 
         [0037]      FIG. 7  illustrates an exemplary method for disassociating a member from an IBSS cell in accordance with one embodiment. The method can be implemented in connection with any suitable hardware, software, firmware or combination thereof. In at least some embodiments, the method is implemented in software in the form of computer-readable instructions that reside on a computer-readable medium. 
         [0038]    At  702 , a member of an IBSS cell decides to disassociate from the IBSS cell. At  704 , a determination is made as to whether the member requesting disassociation is the initiator of the IBSS cell. If the requesting member is not the initiator, then a disassociation request is sent by the requesting member to the initiator at  706 . A disassociation request is a data packet that contains specific data fields, as illustrated below in table 4. The data fields listed in table 4 are for purposes of illustration only, and other disassociation requests may contain different amounts and types of data fields.

         [0039]    At  708 , a determination is made as to whether the initiator received the disassociation request. If the initiator did not receive the disassociation request, then the requesting member is disassociated at  709 . If the initiator did receive the disassociation request, then the status of the requesting member&#39;s IP address is updated by freeing the address of the disassociating member at  710 , thus making it available. At  712 , the requesting member is disassociated from the IBSS cell. 
         [0040]    Returning to act  704 , if the member requesting disassociation is the initiator of the IBSS cell, the initiator then transmits an initiator assignment request (IAR) to one or more of the other IBSS cell members at  714 . The primary purpose of the IAR is to solicit another member of the cell to take over the role of the IBSS cell initiator from the initiator requesting disassociation. An IAR is a data packet that contains specific data fields, is illustrated below in table 5. The data fields listed in table 5 are for purposes of illustration only, and other IARs may contain different amounts and types of data fields.

         [0041]    At  716 , a determination is made as to whether another member of the cell has responded to the IAR. If another member of the cell is willing to assume the role of the IBSS cell initiator, then that member may transmit an initiator assignment response packet to the requesting initiator. The initiator assignment response packet contains certain data fields, as illustrated below in table 6. The data fields listed in table 6 are for purposes of illustration only, and other initiator assignment response packets may contain different amounts and types of data fields.

         [0042]    If the initiator receives an initiator assignment response packet from another member of the cell indicating that the member is willing to assume the role of the IBSS cell initiator, then the responding member is reassigned to the role of the initiator at act  718 . The reassigned initiator may then begin performing the tasks previously performed by the disassociating initiator (e.g. advertising the cell, etc.). 
         [0043]    Referring back to act  716 , if no members respond to the IAR, or if the responses received by the initiator indicate an unwillingness by the responding members to assume the role of the initiator, the initiator may resend the IAR at  720 . Act  722  then determines if any members of the IBSS cell have indicated a willingness to assume the role of the IBSS cell initiator. If a member of the cell has indicated a willingness to assume the role of the initiator, then, as discussed above, the willing member is reassigned as the IBSS cell initiator at act  718 . If at this point no members indicate a willingness to be the initiator, then, in some embodiments, the IP address of the initiator is indicated as available at  710  and the initiator is disassociated at  712 . In some embodiments, the failure of any other member to assume the role of the IBSS cell initiator results in a situation where the IBSS cell will operate as a legacy IBSS cell and thus there will by no initiator to provide IP addresses to joining members.
