一种基于神经网络的无线TCP性能改进机制

A Enhanced Wireless TCP Performance Scheme Based on Neural Network

传统TCP拥塞控制机制由于无法区分拥塞丢包与无线误码丢包,使其在无线环境中传输性能急剧恶化。从避免无线误码丢包出发,提出一种利用传统拥塞控制机制得到的参数(往返时间、重传数据量、拥塞窗口等)。基于无线环境的误码情况和神经网络算法进行TCP段尺寸调整的TCP性能改进方案。仿真结果表明,基于神经网络的TCP改进机制性能得到明显改善。

The Transmission Control Protocol（TCP） has been a factual standard in the Internet today and it does not work in gear in wireless network because it only attributes packet loss to congestion.A scheme of adjusting TCP segment size based on neural network and wireless network is proposed.Simulation results show that this scheme can improve TCP protocol performance in wireless network.
