摘　　要：针对传统ZigBee路由算法存在RREQ分组洪泛、能耗过高和通信效率低等问题,本文引入能量预警机制,设计一种优化的分簇路由算法。算法吸取Cluster-Tree和AODVjr的优点,设置节点能量预警等级,优化路由选择机制,适时启动备用节点,有效避免关键节点过早死亡,降低网络分割风险。仿真结果表明,该算法可提高网络通信效率,均衡网络能量,延长网络运行周期。Aiming at RREQ packet flooding, excessive energy consumption and low communication efficiency in traditional ZigBee routing algorithm, this paper introduces energy early warning mechanism and clustering idea, and designs an optimized ZigBee routing algorithm. The algorithm combines the advantages of Cluster-Tree and AODVjr to set the node energy warning level, optimizes the routing mechanism and starts the standby node timely, thus effectively avoiding the premature death of key nodes and reduces the risk of network segmentation. The simulation results show that the algorithm helps to improve the network communication efficiency, balance the network energy and prolong the network operation cycle.
