Patent ID: 7512079

Claim:
A method to assure node connectivity in an ad hoc wireless network comprising a wireless main controller, a plurality of wireless nodes having a plurality of neighboring nodes and a plurality of wireless links connecting the wireless main controller, the plurality of wireless nodes and the plurality of neighboring nodes, the method comprising: computing a composite threshold for each of a plurality of neighboring nodes of a plurality of nodes, wherein computing the composite threshold further comprises; identifying an energy level and a signal power level for each of the plurality of nodes; determining a weighting factor; identifying a normalized energy level for each of the plurality of neighboring nodes; identifying a normalized signal power level for each of the plurality of neighboring nodes; calculating the composite threshold for each of the neighboring nodes based on the relationship: composite threshold=(weighting factor*normalized energy level)+(1-weighting factor)*normalized signal power level) assigning a mobility to each of the plurality of nodes based on the composite threshold for each of the plurality of neighboring nodes; and using the mobility assigned to each of the plurality of nodes to assure node connectivity in the ad hoc network.
