| 摘 要： | 无线传感器网络由能量受限的节点组成,高效节能的路由算法是路由设计的关键问题。在LEACH算法的基础上,提出了一种新的分簇式路由策略,从簇头个数的确定、簇头选举方法对LEACH算法进行了改进,数据传输方式允许采用多跳方式与基站节点通信,仿真结果表明该算法具有降低网络能耗、延长网络生命周期的优点。

| Abstract: | Wireless Sensor network contains a large number of nodes,whose battery power is very limited,high-efficient and low-power routing algorithm is the pivotal problem.This paper put forwards a new clustering routing algorithm based on LEACH,which improves LEACH with numbers of cluster heads and the choosing cluster heads,the new algorithm adopts multi-hop to communicate with the Base Station,Experimental result indicates that the new algorithm has the advantages of reducing energy consumption and prolonging the lifetime of the sensor network. |
