摘要


为了减少传感器节点的能耗,延长无线传感器网络的生命周期,提出了一种基于节点休眠机制的覆盖控制算法.其基本思想是:网络中所有传感器节点根据邻节点的个数、与邻节点之间的距离来决定是否进入休眠状态,以此来控制每一轮中活跃节点的个数,减少网络的能耗.实验仿真结果表明,在保证网络的覆盖情况下,该算法能够减少活跃节点数,降低网络覆盖冗余度. In order to reduce the energy consumption of sensor nodes and prolong the wireless sensor networks lifecycle, a coverage control algorithm in combination with the existing research is proposed. To control the number of active nodes in each round and reduce the energy consumption of the network, all the sensor nodes select the sleep or active base on their own with a consideration of the neighbor node information. The simulation results show that this algorithm can reduce the number of active nodes and improve coverage under the condition of guaranteeing the network coverage.
