On the probability perception model WSN distributed k-coverage control algorithm

Wireless sensor network coverage control commonly makes nodes dormancy and arousal by algorithm based on 0-1 apperceiving model. The algorithm doesn´t reflect practical conditions. Aiming at the problem, this paper adopts the probability perception model, puts forward a new distributed k-coverage control algorithm, the node exchange information with neighbor-nodes and finds k advantage nodes on energy and ability of perception of neighbor nodes, and then sends corresponding awakening information. By the ways, every node is k-coverage controlled. It realizes working nodes decrease and working time of network increase. The simulation results have validated its effectiveness.
