摘要 无线传感器网络是一种无线自组织网络,由电池能量有限的节点组成.因此,节能、能量有效性、能量平衡等技术是无线传感器网络的关键.该文在全面分析原有路由协议基础上,利用成簇概念,提出一种新的路由协议改进方案,实现负载平衡.改进方案引入一个表格来记录各节点的区域编号,让能量在节点间的传输更加有序.模拟仿真的结果显示,该改进方案能更好的提高网络的寿命. The wireless sensor network is a type of the wireless ad-hoc networks. It is composed of nodes with limited battery power.Energy saving,energy efficiency,energy balance are important technologies to prolong service life of wireless sensor networks.This paper entirely analyzes LEACH routing protocols,and suggests a novel routing protocol improvement LEACH-NEW with a table which records sector IDs for nodes.It let energy transmit among nodes more orderly.Simulation results show that the scheme has a better performance than other schemes in term of the network lifetime.
