摘　　要：移动自组网是由无线移动主机组成的没有基础设施或集中管理中心的临时性网络。在其组建应用过程中,路由协议起着重要的作用。文中基于仿真软件NS2对移动自组网三种典型路由协议DSDV、DSR、TORA在TCP与CBR业务下的性能进行了比较分析。仿真结果表明,在发送速率144kb/s时,DSR与DSDV性能优于TORA,且TCP业务性能优于CBR业务。Mobile Ad hoc network is composed of wireless mobile nodes communicating with each other in absence of any infrastructure and centralized control management. Routing protocol plays an important in constructing the mobile Ad hoc networks. In this paper, the simulation based on NS2 is carried out, and the performance of the three typical routing protocols as DSDV, DSR and TORA under TCP and CBR traffic is analyzed and compared. The simulation results indicate that in the transmission rate of 144 kb/s, the performance of DSR and DSDV is better than that of TORA, and the performance of TCP traffic better than that of CBR traffic.
