Abstract: ZigBee focuses on short-haul, low data rate. The mesh routing protocol for ZigBee is built on the AODV, adopting an effective routing protocol and reducing overhead for route discovery may interfere with network traffic. Based on the ZigBee mesh network, this paper improves AODV route protocol, and proposes a new AODV_Cluster rouote protocol. AODV_Cluster divides the ZigBee network topology into one or more logical clusters. A cluster label uses the ZigBee address allocation, and the one cluster can share a new routing. Simulation shows this protocol not only keeps the AODV merit, but also advances the scalability. Especially in dense network, its performance excells AODV.

摘要： ZigBee是一种短距离、低速率无线网络通信技术，ZigBee网状网的路由是建立在AODV协议基础上的。采取一种有效的路由协议并能减少路由的负载对于整个网络的负荷的减小非常关键。在ZigBee网状网的基础上，对AODV路由协议进行改进，提出一种新型的分簇路由协议AODV_Cluster，把整个ZigBee网络分成多个簇，一个簇的标签是根据簇首的短地址来实现的，而且同一个簇内的路由信息共享。仿真结果表明，协议既保持了AODV的优点，又提高了网络的可扩展性能，特别是在网络的节点数较多时，性能明显优于AODV。
