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.

A system (100) and method (400) for mesh/ad hoc participation is provided. The method 400 can include compensating a first service provider (510) for allowing a device (539) of a second service provider (530) to operate in an ad hoc network (500) operated by the first service provider, and determining network resources utilized for providing communication among nodes in the ad hoc network. The compensation to the first service provider accounts for network resources utilized by the device for communicating within the ad hoc network. Resources can include equipment that is operated, owned, leased, rented, borrowed, or shared by the service provider. The method 400 allows users to roam to other networks without a service subscription agreement.

Techniques are provided for allowing a node (300) in an ad hoc network to deterministically decide whether to relay broadcast information to another node in the ad hoc network. The node (300) receives broadcast information and measures received signal strength (RSS) of the broadcast information. The node (300) may determine if the measured RSS is below a low threshold, and if so, can relay the broadcast information to neighbor nodes. Otherwise, the node (300) can also determine if the measured RSS is above a high threshold, and if not, wait for a waiting period before relaying the broadcast information to the neighbor nodes. The node (300) may dynamically adjust the low threshold by decreasing the low threshold as the number of neighbor nodes increases and may dynamically adjust the high threshold by increasing the high threshold as the number of neighbor nodes decreases.

A node (200) includes a processor (201) for determining neighbor nodes in a routing path to a destination based on a routing table associated with the node (200). The node (200) includes a memory for storing a first authenticated tokens. The node includes a transmitter (203) for transmitting a first request-to-route (RTR) message including an indication specifying information units (IUs) from the first node to the neighbor nodes in a routing path from the first node to the destination. The node (200) includes a receiver (205) for receiving a neighbor reply message from one of the neighbor nodes to the first node which indicates that the neighbor node will route the information units (IUs). The transmitter (203) transmits a second authenticated tokens from the first node to one of the neighbor nodes. The second authenticated tokens are converted into a tradable entity and provide compensation to the neighbor node selected.

摘要:
A dynamic and distributive aggregation method in which a node determines the frame size of an aggregated frame based on or according to a transmission time of one or more of the received frames. This scheme to aggregate frames is based on the average packet size and average transmission time in the neighborhood. The method enables the aggregated packet size to dynamically change based on the neighborhood conditions. Usage of link rates and fair transmission time assignment enables the high data rate nodes to send more traffic but not to an extent of over-utilizing the channel thus achieving higher throughput efficiencies while maintaining fairness within a high data rate multi-hop wireless communication network.

A system and method for improving a current wireless communication route, between a source node and a destination node in an on-demand wireless communication network, enables the current communication route to be improved even when the current route has not failed. The method includes analyzing at a local node a packet transmission from the source node, the packet transmission comprising a current route metric (step 705). The local node then determines that it can provide an improved wireless communication route, between the source node and the destination node, having a better route metric than the current route metric (step 710). A route improvement message is then transmitted from the local node to the source node (step 740).
摘要:
Systems and methods are provided for determining a number of spatial channels to use to transmit a data packet from a source node to a destination node. This determination can be made based on a Probability of Channel non-Correlation (PCC) function that is generated and updated by the source node based on feedback from the destination node. The PCC function indicates a probability of whether a plurality of spatial channels are non-correlated.

A method provides for selecting a communication interface towards an access point by a wireless communication device. The method includes receiving one or more HELLO messages from the access point; determining whether any of a plurality of communication links is being used to reach the access point by evaluating at least one field of each of the received HELLO messages; penalizing a link metric of a communication link when the communication link is being used; and selecting a communication interface towards the access point, wherein the selected communication interface is coupled to a best communication link having a best link metric.
