一种基于LEACH路由协议的改进算法

Abstract

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.

Key words: wireless sensor network;routing protocol;LEACH;K-medoids
