基于能量均衡的ZigBee路由算法优化

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。

Improved ZigBee routing algorithm based on energy balance

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 effecti-ve...
