摘　　要：为了实现ZigBee网络的能量均衡,延长网络生存时间,针对现有基于能量均衡的ZigBee网路路由算法的不足,根据节点父子和位置关系适当控制RREQ包转发方向,提出了针对RN-节点改进邻居表使RN-节点具备路由功能,并定义了考虑因素全面的路由代价和能够实时更新的节点能量等级,从而实现了AODVjr路由算法和Cluster-Tree路由算法基于能量均衡的真正结合。通过仿真与原算法和现有的基于能量均衡的路由算法进行比较,比较结果表明了优化的ZigBee网络总体能量消耗与死亡节点出现时间和数目。To achieve energy balance and prolong the survival time of ZigBee network, aimed at the deficiency of existing ZigBee network routing algorithm based on energy balance, based on a method of controling the direction of the RREQ packet according to the relationship of father-son and location between nodes, an improved neighbor table to make RN- have routing function and RoutingCost with comprehensive factors and PowerLevel that can update in real-time are proposed to combine the AODVjr and Cluster-Tree effectively. Simulation results show that the optimization of the ZigBee network in the overall energy consumption and the time of occurrence and the number of death nodes.
