摘要： ZigBee网络的AODVjr算法在路由发现过程中存在大量路由请求包(RREQ)分组洪泛的问题。为此，结合节点能量和Cluster-Tree算法，提出一种改进的AODVjr算法。在路由选择时尽量避免能量较低的节点，并对RREQ分组的大致方向和传输距离进行控制。仿真结果表明，该算法能有效降低网络总体能耗，合理分担网络负载，降低死亡节点数，延长网络的生命周期。

Abstract: Aiming at a large number of RREQ packet flooding problems in the route discovery process, an advanced AODVjr algorithm resulting from node energy and Cluster-Tree algorithm is proposed. The new AODVjr algorithm tries to avoid the low-energy nodes when choosing route and can control the general direction and hops of the RREQ packet. At the same time, the simulation results indicate that the new AODVjr algorithm can cut down the total energy cost effectively, share the network load properly, reduce the death of nodes, and extend the network life cycle.
