摘要： In one embodiment, a method resolves cliques formed in a network comprising a plurality of nodes that are communicatively coupled to one another over at least a first channel. The method comprises, at each node, wherein that node is a member of a current clique: listening asynchronously for data on the first channel from a first neighbor's neighbor node of that node. The method further comprises, at that node, when a first valid frame is received on the first channel from the first neighbor's neighbor node of that node, listening asynchronously for a second valid frame on the first channel from a first neighbor node of that node. The method further comprises, at that node, when the second valid frame is received on the first channel, checking if the first valid frame and the second valid frame are both from the same other clique, and, if the first valid frame and the second valid frame are both from the same the same other clique, determining if that node should defect from the current clique towards the other clique.

摘要： A multi-channel TDMA network having priority based is provided. A network includes a plurality of channels, and a plurality of nodes adapted to transmit and received data. Through each channel, every node is coupled to communicate data with every other node. Within each channel, each node is assigned a unique priority rank. Only the node with the highest priority rank is permitted to transmit data during a time slot. For each channel of the multi-channel network, the plurality of nodes are ranked in a different priority direction.

摘要： In one embodiment, a node comprises an interface to communicatively couple the node to a channel. The channel communicatively couples the node to a first neighbor node and a first neighbor's neighbor node in a first direction. When the node relays relayed data along the channel, the node compares data received from the first neighbor node with data received from the first neighbor's neighbor node. The relayed data comprises: at least one of: the data received from the first neighbor node and the data received from the first neighbor's neighbor node; and information indicative of the results of the comparison.

摘要： A parasitic time synchronization network is provided including a plurality of nodes, one or more hubs, each hub having communication links with the plurality of nodes and one or more guardians. Each node is adapted to transmit and receive data and communicate with every other node through the one or more hubs. The communication links between any one hub and the plurality of nodes defines a communication channel. Each guardian is associated with one communication channel. Each node is assigned a time slot in which it is permitted to transmit data through an associated hub of the one or more hubs. A guardian of an associated channel blocks propagation of data transmissions between the plurality of nodes through the associated hub allows only data transmissions from one of the plurality of nodes, wherein the guardian periodically receives a cluster of beacons generated by a plurality of the plurality of nodes.
