摘　　要：移动Ad hoc网络是移动节点动态临时组建的自组织网络,路由协议一直是Ad hoc网络研究的关键问题.文中提出了一种新的AODV改进协议AODV-NM,它能够根据节点速度自适应的调整RREQ泛洪频率,实现稳定路径的选取.仿真结果表明,AODV-NM能够有效降低网络路由负荷,同时改善了时延与分组投递率等性能.Mobile Ad hoe network is a self-organized network formed dynamically and temporarily by mobile nodes. Routing protocols is a key problem and critical to mobile ad hoe network. In this paper, an effective modified version of AODV, named AODV-NM, is proposed. AODV-NM is able to adjust the frequency of RREQ flooding to obtain the stable path. The simulation results show that the new protocol could decrease routing load in ad hoe networks and improve the performance of delay and PDF simultaneously.
