LEACH协议是无线传感器网络中典型的分簇式路由协议,通过分析LEACH协议的优缺点,针对该协议的簇首选择机制进行改进,提出了LEACH-SERP的分区域簇首选择算法,该算法将整个网络分成若干个扇形区域,在每个扇形区域内独立地运行改进的LEACH协议,同时区域簇首与基站之间的通信由传统的单跳改为多跳,并进行了仿真分析。仿真结果表明,LEACH-SERP协议有效节约能量,平衡网络负载,延长网络生存时间。
LEACH Protocol is a typical clustering routing protocol of WSN.This paper researched the advantages and disadvantages of LEACH Protocol,and put forward LEACH-SERP zoning cluster head selecting algorithm contraposing improving cluster head selecting mechanism of clustering routing protocol,which divided the network into several sector area,and independently ran the improved LEACH protocol while the cluster heads of different zones communicated through multi-hops instead of single-hop with simulating analysis.The simulation showed that LEACH-SERP Protocol could effectively save anergy,balance network load and extend the network's lifetime.
