摘　　要：在移动Ad hoc网络中,节点是随意移动的,为确定某一时刻的网络拓扑,必须首先探测出网络中所有节点的位置和移动特征,这样也能避免Ad hoc网络频繁出现链路故障。为此,提出一种继承自AOMDV协议的增加节点预测的新型路由协议NP-AOMDV,并与AOMDV在吞吐量、端到端时延、路由控制开销等做性能对比,通过NS2下的仿真结果分析可知,NP-AOM-DV比AOMDV性能有了一定的提高。Nodes are random moving in a mobile Ad hoe network, so we must detect all nodes in the network location and movement characteristics before determining the topology of the network are detected. This paper introduces a new routing protocol （NP-AOMDV） inherited from the Ad Hoc On- Demand Multipath Distance Vector Routing （AOMDV）, which increases node prediction. Predicting the node movement can be done by avoiding the frequent link failures in Ad hoc environments. The performance of the NP-AOMDV, throughput, End-To-End delay, routing control overhead compares with the AOMDV routing. NS2 simulation results show the improved network performance of the proposed approach （NP-AOMDV） over than existing multipath routing protocol （AOMDV）.
