Research on Probabilistic Coverage Control Algorithm for Wireless Sensor Network

Coverage control is an effective method to alleviate the energy-limitation problem of sensor nodes in wireless sensor networks. Most of current researches were based on geometry calculation of binary sense model which is limited and inaccurate in practical application. Aiming at the problem, this paper adopts the probability sense model, puts forward a new coverage control algorithm (PSMC), which takes energy efficiency as important index. The probability sense model describes the coverage 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.
