  • Patent number: 8532072
    Abstract: A system and method of operating a wireless network having a plurality of nodes. Each node determines whether to replace the beacon node. When a node determines that the beacon node is to be replaced, the node determines whether it should nominate itself as a potential replacement beacon node. The decision whether to nominate itself as a potential replacement beacon node is a function of a nomination probability associated with the node. If the node determines that it should nominate itself as a potential replacement beacon node, the node sends out one or more beacon signals. Each node then adaptively modifies the probability of nominating itself as a function of the number of beacon signals received from other nodes. Beacon signals are received by potential replacement nodes and, if the potential replacement beacon node has received a beacon signal from a higher ranking potential replacement beacon node, the node removes itself as a candidate for the replacement beacon node.

When a node determines that the beacon node is to be replaced, the node determines whether it should nominate itself as a potential replacement beacon node. The decision whether to nominate itself as a potential replacement beacon node is a function of a random number generated by the node. If the node determines that it should nominate itself as a potential replacement beacon node, the node sends out one or more beacon signals. Beacon signals are received by potential replacement nodes and, if the potential replacement beacon node has received a beacon signal from a higher ranking potential replacement beacon node, the node removes itself as a candidate for the replacement beacon node.
