| 摘 要： | 无线传感器网络的生存时间受传感器节点软硬件条件的限制,改进传感器网络路由协议是延长网络生存时间的有效途径。LEACH协议是最早提出的经典分层路由协议,文中基于LEACH协议提出改进,应用K-medoids算法改进LEACH协议的簇首分簇机制,并通过Matlab仿真实验,证实了改进后的LEACH算法在均衡化网络能耗,延长网络的生命周期方面具有优越性。

| Abstract: | Due to the limitation of software and hardware of the sensor node,lifetime of Wireless sensor network(WSN) is limited,and the research of WSN routing protocol is one of the most effective ways to extend the network lifetime.LEACH protocol is a classical cluster routing protocol.This paper proposes an improvement based on LEACH protocol,applying K-medoids algorithms to improve the mechanism of the selection of cluster head.Simulation results have confirmed that the improved LEACH protocol is superior in extending network lifetime and equalizing energy wastage. |
