【摘要】 基于簇的无线传感器网络路由协议是目前国际上研究重点之一。本文针对LEACH (low_energy adaptive clustering hierarchy)无线传感器网络路由协议,以不影响终端用户获取信息为前提,提出了一种改进方法,该方法首先根据剩余能量进行节点筛选,减少参加采样的节点数量;其次对成簇阶段出现的异常情况的节点进行了放弃处理。仿真结果显示新方法提高了传感器网络的能效,延长了系统的工作寿命。更多还原

【Abstract】 Recently the routing protocol of WSN(wireless sensor networks) based on clustering hierarchy has been one of the most crucial research topics around the world. An improved strategy based on LEACH (Low Energy Adaptive Clustering Hierarchy) was proposed in this paper, which can save more energy of WSN and can’t affect the information acquisition of end-user. Rrstly we pick out some node in terms of energy detecting and decrease the number of the sampling nodes. After that, the nodes in a abnormal situation are given up. Experiment results show that the proposed method can reduce energy dissipation and extend the lifetime of the system.更多还原
