中文摘要：
在无线传感器网络中进行覆盖控制能有效缓解无线传感器网络中节点能量受限的问题,通常采用的是基于二元感知模型的几何方法计算休眠冗余节点,其算法在实际应用中受到局限,不够精确。针对此问题,将提高能量利用效率作为重要指标,采用概率感知模型,提出一种新的覆盖控制算法（PSMC）。仿真结果表明,PSMC算法在较好地保持网络覆盖度的同时,可关闭大量冗余节点,有效地延长了网络寿命。
英文摘要：
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.
