无线传感器网络中,LEACH协议是典型的分簇路由协议。文章针对LEACH协议的缺点,结合PEGASIS协议的优点,从簇首选择、簇的形成、簇问路由等方面对LEACH协议进行了改进,设计了一种能量均衡的分簇路由协议EBLP,并进行了仿真分析。仿真结果表明,EBLP协议节约了能量,平衡了能量消耗,延长了无线传感器网络的生存时间。
Among routing protocols of WSN, LEACH is one of the typical cluster-based algorithm. This paper improved LEACH from cluster-heads selection, cluster formation and inter-duster routing based on the shortness of LEACH and the advantage of PEGASIS. An energy balanced cluster-based routing protocol named EBLP was proposed,and it was simulated. The results of simulation shows that EBLP can save energy, balance energy consumption and prolong the lifetime of WSN.
