基于分层簇的无线传感器网络路由协议

Wireless Sensor Networks Routing Protocol Based on Layered-Cluster

在无线传感器网络技术中,路由技术是研究的热点.本文分析经典分簇路由算法LEACH协议的不足,提出一种基于分层簇路由协议LEACH-L.该算法把无线传感器网络覆盖区域依据普通节点据汇聚节点的远近将传感区域分成大小不等的层,在层内进行分簇,并依据能量因子参数优选簇首.仿真结果表明,该算法能有效地减少能量损耗,延长网络的生存周期.

In the wireless sensor network, the focus of research is routing technology. The Leach＇s shortcomings were analyzed in this paper, a routing protocol（Leach- L） based on hierarchical cluster was proposed. According to the distance of node to the sink node, LEACH- L divided the wsn＇s area into some layer, which was the ranging in size from the distance. The simulation results indicated that the Leach- L protocol could efficiently save the energy consumption and prolong the wireless sensor network lifetime.
