摘要
为改进传输控制协议TCP在无线移动网络环境下的通信性能,减少网络拥塞,分析了Ad Hoc网络Web通信时数据丢失的主要原因,提出了利用探测包探测网络传输性能重新划分网络状态的方法来改进TCP拥塞控制。仿真结果表明,改进后的TCP拥塞控制机制能够明显提高无线多跳Ad Hoc网络环境下Web通信的性能,避免拥塞。
To improve the performance of the transmission control protocol in wireless mobile communications network environment, and reduce network congestion, the reason of data lost in Ad Hoc network supporting web communication is discussed.An improved TCP algorithm is discussed.Finally, our research work is summarized, and some perspectives are done for the future work.The simulation results showed that improved TCP congestion control mechanisms is able to significantly enhance the web communication performance and avoid the network congestion in the wireless Ad Hoc network.
