Research on probabilistic coverage control algorithm for wireless sensor network
无线传感器网络概率覆盖控制研究*

Coverage control is an effective method to alleviate the energy-limitation problem of sensor nodes in wireless sensor networks. Most of current researches are based on geometry calculation of binary sense model which is limited and inaccurate in practical application. Aiming at the problem, this paper adopted the probability sense model, put forward a new coverage control algorithm (PSMC), which took energy efficiency as important index. The probability sense model described the cove-rage control more accurately. Simulation shows PSMC algorithm can shut down a large number of redundant nodes and extend effectively network lifetime while coverage ability does not reduce.
