| 摘 要： | DSR犤1,2犦协议是一种用于无线Adhoc网络的路由协议。笔者在Linux操作系统下实现了DSR路由协议,并以此为基础,搭建了一个无线Adhoc网络的实验床(Testbed)。在实验床的真实场景中,笔者从路由性能、协议开销和TCP业务的传输性能三个角度对DSR协议进行了一系列实验和性能评价工作。论文对该实验床的搭建和所得到的性能测试的结果进行了介绍。实验中,发现在无线多跳Adhoc网络的环境下,TCP业务的性能很差,此外也给出了对这种现象的解释。

| Abstract: | DSR protocol is a routing protocol that is used in the wireless Ad hoc networks.Authors have implemented the DSR protocol in Linux Operating System.And based on this implementation,authors set up a wireless Ad hoc network testbed.In this realistic environment ,authors have done some experiments to evaluate the performance of DSR protocol.The experiments focus on three aspects:the routing performance,the overhead of the protocol and TCP traffic performance.In this paper,the testbed and results of experiments are introduced.Authors find TCP presents poor performance in Wireless Ad hoc network.An explanation of this phenomenon is also given. |
