一种能量有效的无线传感器网络覆盖控制算法

Energy Efficient Coverage Control Algorithm for Wireless Sensor Networks

覆盖问题是WSN(无线传感器网络)的基本问题,合理的覆盖控制可以有效地延长WSN的生存时间.提出一种能量有效的WSN覆盖控制算法(EECCA).算法中,节点采用布尔感知模型,节点根据自己的能量大小和连续未当选工作节点的轮数,来触发定时器进行工作节点选择,并根据邻居节点的能量信息进行了工作节点优化.仿真实验结果表明,算法不仅可以满足覆盖率要求,而且在减少总体能量消耗方面也有很好的改善.

Coverage is the basic problem in wireless sensor networks, coverage control can prolong network lifetime efficiently. An energy efficient coverage control algorithm for wireless sensor networks { EECCA } is proposed. Adopting the Boolean sensing model , EECCA elects the working nodes based on the energy of node and the rounds of not elected working nodes to trigger the timers. Then. according the energy of neighbor nodes to optimize the working nodes, and the rest of the nodes sleep. Our simulation analysis demonstrate that not only meet the coverage ratio , but also have a good performance in the overall energy consumption.
