摘　　要：利用OPNET软件仿真,建立有50个节点且一些节点可以移动的Ad hoc网络拓扑,在网络拓扑不变和网络拓扑变化以及网络负载在高、低场景下,仿真分析2种Ad Hoc网络路由协议DSR、TORA在不同场景下对业务量、网络时延和丢包率性能参数的影响.得出在网络拓扑不变,高负载时使用TORA的网络性能比使用DSR协议好,而在网络拓扑变化,低负载时使用DSR协议要好一些.在网络拓扑发生变化时,使用TORA协议FTP的发送量比DSR大的结论.Base on OPNET modeler software, an Ad hoc model including 50 nodes and some movable nodes was built in this paper. On the eases of the changing network topology or not changing network topology, and the low or high network load, two on-demand typical muting （DSR and TORA） protocol of Ad hoc network are analyzed by simulation. The quantity of business, the network delay and the rate of packet loss are parameters of network performanee. The conclusions have gotten that TORA is better than DSR in the case of network high load; DSR is better than is TORA in the case of network low load; Performance of network of TORA is better when network topology changes.
