摘　　要：对移动Ad hoc网络现有的AODV协议进行改进,实现一种将主动路由与被动路由相结合的新型混合路由方式,并增加范围限定机制以及折中距离和能量机制,改进后的HR-AODV协议在无线Mesh网络下具有较好的性能,可在网络层更好地服务于上层应用。NS2仿真结果表明,HR-AODV协议在时延、丢包率以及吞吐量等方面有较大改善,具有较强的健壮性和容错性。This paper improves the AODV protocol used in the wireless Ad hoc network,realizes a new hybrid routing architecture by combining active and passive protocol,increases range limitation mechanism and compromise of distance and energy,the improved HR-AODV protocol has a better performance in Wireless Mesh Network（WMN）,and it is more suitable for upper level applications in network layer.Simulation results using NS2 show that the HR-AODV protocol achieves a larger improvement in the network latency,packet loss rate,thought and so on,it has stronger robustness and fault tolerance.
