摘　　要：路由算法是Ad hoc网络最为重要的技术之一,但Ad hoc网络拓扑结构的频繁变化和带宽受限,给路由协议的设计带来了严峻的挑战。介绍了一种新的NRP Ad hoc网络路由协议,该协议能自适应地广播链路状态消息,因此能以较小的带宽消耗获得较精确的路由。最后研究了流行的网络仿真工具NS,并在NS的基础上对该协议进行了实现,对网络作了简单的仿真。Routing algorithm is one of the best important technologies in Ad hoc network, But me features of Ad hoc network, such as dynamic topologies, bandwidth - constrained, give great challenge to the development of the routing protocol. In the paper, a novel muting protocol is introduced, which is more desirable for Ad hoc network. The protocol can broadcast link state messages adaptively, so it can acquire more precise route at the lesser cost of bandwidth. At last, the NS, one popular network simulator is analyzed, which provides the foundation for the realization of NRP. And then the protocol is realized on the basis of NS, simple simulation of NRP is done by simulator.
