摘要

延长传感器网络寿命，减少能量消耗，是无线传感器网络的研究重点，本文在研究层次结构及有效能量的路由协议代表LEACH（low energy adaptive clustering hierarch，低功耗自适应集簇分层型）协议的基础上，提出一种高效聚类路由算法（LEACH-Ⅱ）。该算法在簇头选举中综合考虑了节点剩余能量、平均能量和最大能量，并限制了各簇的成员数量，同时簇头之间形成第一簇头，利用多跳方式平衡网络的负载。仿真结果表明，改进的算法降低了能量的消耗，延长了网络的生存周期，保证了系统的负载均衡。

Abstract

One of the most popular research focuses of wireless sensor network is postponing the life cycle of sensor network as well as reducing energy consumption.An efficient clustering routing algorithm based on LEACH（low energy adaptive clustering hierarch）was presented，which is the representative of hierarchy based protocol in wireless sensor network.The residual energy，average energy and maximum energy are considered in this algorithm while electing the cluster header.It can also limit the number of members of each cluster.At the same time，it can produce the first cluster header among the cluster heads which will use the multi-hop mode to balance the load of network.The simulation results show that this improved algorithm can reduce the energy consumption，extend the network life cycle and ensure the load balance of the system.
