摘要

通过路由算法减少节点的能耗、延长网络的寿命是无线传感器网络的研究重点之一.探讨了能量高效的分层无线传感器网络路由算法,提出一个基于地理位置信息静态分簇,根据节点剩余能量及节点在簇内的位置选择簇头的分层路由算法(GSCH).适用于静态无线传感器网络.仿真实验结果表明该路由算法有效地减少分簇成形及簇首选择的能耗,延长了整个网络的寿命.%It is one of the key sectors of research for wireless sensor networks to use routing algorithm to reduce nodes' energy consumption and prolong networks' lifetime.In this paper we discuss the energy-efficient hierarchical routing algorithm for wireless sensor networks, propose a hierarchical routing algorithm suitable for static wireless sensor networks which statically clusters based on nodes' geographical location information and chooses cluster-head by node' s residual energy and the location of the node in cluster (GSCH).Simulation results show that the routing algorithm effectively reduces the energy consumption of clustering and cluster-head choosing, thus the lifetime of entire network is prolonged.
