Abstract
A system and method is disclosed wherein a plurality of nodes within an ad hoc wireless network are able to wirelessly communicate with each other. Each node includes a first data array for storing a node identifier used in selecting a clusterhead and a second data array for storing information relating to the node providing the node identifier for selecting the clusterhead to the node. Control logic of each node is configured according to a heuristic wherein the node initially determines a largest and smallest node identifier for each node. The node selects a clusterhead for the node responsive to the largest node identifier and the smallest node identifier using a set of predefined rules. The nodes within the area are then linked with the selected clusterhead.
