基于OPNET的Ad hoc路由协议比较与分析

在过去的几年中，人们对于Ad hoc网络进行了大量的研究，由于Ad hoc网络自身的特殊性，其路由协议的设计与传统固定网络有很大不同，因而也成了研究的焦点之一。丈中首先介绍了Ad hoc网络中的路由协议设计的几种策略，接着介绍了几种典型的Ad hoc路由协议，最后通过OPNET仿真并获取数据，通过考察路由发现时间、传输时延、路由跳数及网络吞吐量等性能指标，对两种典型路由协议进行综合评测，进而给出了结论，并对未来的研究指出了方向。

Comparison and Analysis Of Ad Hoc Routing Protocols Based on OPNET

During the past few years, there has been a lot of research work done with ad hoc networks. In the light of its speciality, the design of its routing protocol is quite different from that of the traditional fixed networks, and thus its research has become a focus. This paper, first describes several strategies in the design of ad hoc networks, then some representative designs of ad hoc routing protocol, then from OPNET simulation and statistics, and by analyzing routing discovery time, transmission delay, hops per route and network throughput, two representative routing protocols are compared and evaluated. The results indicate some.directions for future research.
