摘　　要：介绍了TCP的拥塞控制原理以及动态源路由协议DSR.分析了造成Ad hoc网络拥塞的原因.在此基础上提出了将最小拥塞窗口适当增大,以提高数据吞吐量,改善网络的TCP性能.并以Ad hoc网络中的DSR路由协议为例,用NS2进行仿真对比,证实适当增大最小拥塞窗口确实能改善网络性能.The TCP congestion control principle and source of dynamic routing protocols DSR are introduced, then the reason for the network congestion on Ad hoc network is analysed. On this basis, the way to increase the smallest congestion window properly is proposed which can improve the data throughput and the network performance of TCP. And taking the DSR routing protocol as an example, the results show its effectiveness compared with the simulation experiment.
