| 摘 要： | 移动自组网是一种没有基础设施的临时性自组织网络，在其应用时路由协议是必须确定的基础性问题。本文研究DSR路由协议在不同无线传播环境下的性能，为确定DSR路由协议在无线传播环境下的适用性提供重要依据。仿真结果表明：对于平均端到端时延和MAC层负荷。two—ray ground reflection环境下性能好，而就报文投递率和路由负荷来说，freespace环境下较好，对于在shadowing环境下，各项性能参数表现都较差。

| Abstract: | Mobile ad hoc network is an infrastructureless temporary ,self- organized network. The routing protocol is an important foundation problem when deploying it. In this paper, the performance of Dynamical Source Routing is studied in different wireless propagation environment. The simulation result shows that, average end - to- end delay and MAC load behaves better in two ray ground reflection environment, but packet delivery fraction and routing load behaves better in free space environment, in addition that all performance parameter in shadowing environment is badly. |
