Study and improvement on coverage control algorithm in WSN

The classical Coverage-Preserving Nodes Scheduling (CPNSS) algorithm for Wireless Sensor Network (WSN) has the problems of low efficiency and energy imbalance.This paper proposed an Efficient Coverage-Preserving Nodes Scheduling (ECPNSS) algorithm,which can improve the judging efficiency of redundant sensors,take account of the connectivity of network,and balance the network energy.The simulation results demonstrate that ECPNSS algorithm not only preserves the original coverage,but also improves the efficiency of judging the redundant nodes and reduces the redundancy of network.
