摘要： A method for merging of ad hoc network partitions within an ad hoc network, the method includes forming a plurality of network partitions by forming a security association among each of a group of partitioned nodes. Each network partition includes a Network Identifier. A node operating within one of the network partitions receives an update message from another node, compares its current Network Identifier to the received Network Identifier; and determines whether to update to the received Network Identifier using an arbitration method when the received Network Identifier is different from the current Network Identifier.

摘要： Techniques are provided for selecting a root node in an ad hoc network that contains a plurality of nodes including a first node. According to one implementation of these techniques, a first node can receive a message from at least one of the other nodes. Each message includes a number of primary factors associated with a particular node regarding capabilities of the particular node. The primary factors associated with each node can then be evaluated, and an attempt can be made to select the root node based on the primary factors associated with each node. If the first node is unable to select the root node based on the primary factors associated with each node, then the root node can be selected based on secondary factors associated with each node.

摘要： A communications system and method for exchanging spectrum usage information through a drop box (100) includes one or more central stations (101) that defines a region of operation. A central drop box (102) is associated with the central station (101) for providing a database of spectrum usage information. Stations (103, 105, 107) using the communications system may submit information regarding spectrum usage to the central drop box (102) that affects the region of operation (109, 115) for providing the most efficient and non-interfering uses of the frequency spectrum.

摘要： A method and apparatus for electing broadcast relay nodes (520B, H, M) in an ad hoc network (500). Each node (520A-520O) generates an attribute message including associated parameters. Each node (520A-520O) generates a weighted value (WV) based on the parameters. The WV can be included in the attribute message for that node, can provide a metric for ranking that node to be nominated to be a broadcast relay node, can alternatively provide a probability measure for that node to probabilistically elect itself as a broadcast relay node. The broadcast manager node (520C) receives the attribute messages and elects at least one nominated node as a broadcast relay node (520B, H, M) based on the attribute messages. Each node (520A-520O) can also initiate election of an intermediate broadcast relay node if that node fails to receive a test message within a predetermined time.

摘要： A method for providing reliable multicasting is described. A transmitted multicast packet is received at second devices, each of which in response transmits a first acknowledgement. If a second acknowledgement, which acknowledges the first acknowledgement, is not received within a predetermined time period, the first acknowledgement is retransmitted. If all first acknowledgements are not received within a preset time period, the multicast packet is retransmitted. If the retransmitted multicast packet has been received, at each of the second devices, if the second acknowledgement has not been received the first acknowledgement is retransmitted, while if the second acknowledgement has been received, the retransmitted multicast packet is ignored and no additional first acknowledgement is transmitted.

摘要： A cognitive radio (CR) system (102) includes CR units (108, 110) that determine and update location-based system operating parameters to avoid interference with other systems operating in the same frequency band. Operational Location Uncertainty region and Allowed Location Error regions can be applied. The CR unit trades off between both, available channels and maximum system operating parameters, such that as Location Uncertainty of the CR device increases, available CR channels and location-based CR system operating parameters decrease over a maximum network reach.

摘要： At a first device (102 or 104), a message is received and processed. If the message is processed during a first time period, the first device transmits an acknowledgement message during a second time period; otherwise the first device transmits the acknowledgment message during a third time period. The second time period and the third time period are exclusive of each other.

摘要： An access point (100) transmits at least a first set of parameters intended for a first set of users (102) and a second set of parameters intended for a second set of users (104). The access point communicates with the first set of users during a first time period and communicates with the second set of users during a second time period, wherein the first time period and the second time period are exclusive of each other. Moreover, the first time period and the second time period lapse prior to the AP transmitting a next set of parameters intended for the first set of users.

摘要： Methods for performing client to client communication in a wireless local area network are disclosed. At an ‘n’ tier client in the wireless local area network, a signaling message from an ‘n−1’ tier client is received wherein the signaling message comprises a first period, a second period, and a third period. Communicating with the ‘n−1’ tier client during the first period and communicating with the ‘n+1’ tier client during the third period. At an access point in the wireless local area network, an association table identifying clients in the wireless local area network is created and a first period for client to client communication based upon the association table and traffic in the wireless local area network is determined where the access point does not communicate with the clients during the first period.
