摘要
为有效合理的利用ZigBee网络的能量,延长网络生存时间,该文对已有的基于能量均衡的ZigBee路由算法优化进行改进,根据节点位置关系对RN+节点适当控制RREQ转发的大致方向,限制其向与目的节点相反的方向传输,并实时的更新节点的能量等级。经仿真与原ZigBee路由算法和现有能量均衡ZigBee路由算法比较,结果表明本算法优化了网络总体能耗和死亡节点出现的时间和数目。
In order to make use of ZigBee network energy and extend the network lifetime.This article’s purpose is to improve the algo rithm based on ZigBee for energy balance routing algorithm.Because the location realationship between nodes,the node RN+ can control the forwarding for RREQ.Provent RN+ node tranfer RREQ to the opposite direction of destination node and update nodes energy levels in time.Simulation results shows that this algorithm optimizes the overrall energy consumption and network nodes the time and the num ber compared to ZigBee routing and ZigBee for energy balance routing.
