In order to achieve optimal control of network coverage, reduce energy consumption, this paper presented a distributed , energy efficient, and the node position independent of the sensor network coverage algorithm. In the algorithm, nodes exchanged information with neighbors and worked through the energy of running nodes, other nodes according to their distance from the node with the work, made judgments, or to enter the work state, or into sleep state. Simulation results show that the algorithm can significantly reduce the number of nodes working, thus to reduce energy consumption and prolong network lifetime.%为了实现网络覆盖控制的优化,减少能耗,提出了一种分布的、高效节能、与节点位置无关的传感器网络覆盖算法.在该算法中,节点与邻居交换信息,并通过能量大小竞选工作节点,节点根据自身与工作节点的距离判断决定进入工作状态或休眠状态,并采用在生成树中广播时间同步算法使工作节点网络达到时间同步.仿真结果比较表明,该算法能够明显减少工作节点数,从而减少能量消耗,延长网络寿命.
