摘　　要：传统的ZigBee路由算法存在泛洪式路由请求(Routing Request, RREQ)消耗网络大量能量和网络内节点能耗不均等问题,缩短了网络生存周期。本文提出一种优化选取转发节点的能量均衡路由算法。在路由发现阶段限制RREQ广播半径,路由选择阶段通过多目标优化选取最佳下一跳节点,并且通过节点间周期性交换休眠时序,实现同步低功耗路由机制。基于NS-2.35的实验结果表明,与传统的ZigBee路由算法相比,本算法可以提高数据包的平均到达率,减少数据包的平均端到端延迟和保持网络内节点能量平衡,进而延长网络生存时间。For the traditional ZigBee routing algorithm, there are problems that flooding routing requests consume lots of energy and energy consumption of nodes in the network are uneven, which shorten the network lifetime. An energy balanced routing algorithm is proposed that optimizes the selection of forwarding nodes.The RREQ broadcast radius is limited in the route discovery phase, and the optimal next-hop node is selected in the route selection phase. Synchronous low-power routing mechanism is implemented by periodically swapping sleep timings between nodes. The experimental results based on NS-2.35 show that compared with the traditional ZigBee routing algorithm, this algorithm can improve the average arrival rate of data packets,reduce the average end-to-end delay of data packets, maintain the energy balance of the nodes in the network,and then extend the network lifetime.
