基于OPNET的DSR路由协议的性能分析

无线hd hoc网络是一种不需要基础设施的自组织和自管理网络，网络中所有的节点同时具有终端和路由器的功能。因此网络可以通过节点路由发现机制转发分组，并进行路由维护。该文对DSR（动态源路由协议）进行理论分析，该协议在业务量不大的情况下，相对其他路由协议有较好的性能。并采用OPNET软件对基于DSR协议的Ad Hoc网络的路由开销和时延等关键参数的仿真统计，分析了节点移动速率对路由协议性能的影响。

The Analysis of the DSR Protocol Based on OPNET

An Ad Hoe network is a collection of wireless mobile hosts which forming a temporary network without the aid of any established infrastructure or centralized administration. In such an environment, every host is a terminal and also a router, so the network can complete route discovery and route maintenance by the host. In this paper, the routing protocols used in Ad Hoe network are introduced, especially DSR is detailedly presented due to its most suitable in medium load environment. By simulating using OPNET, it is pointed out that the mobility of host is con- sidered as critical factors to network performance.
