Improvement of wireless TCP based on monitoring error packet loss rate
Han Hu · Journal of Computer Applications · 2011
In wireless environment,TCP erroneously responds to all losses by invoking congestion control algorithm,which results in degraded end-to-end performance.Concerning this problem,this paper proposed a method of wireless TCP based on monitoring the packet loss rate due to bit error in real-time.The data sender cooperated with the router configured with the function of explicit congestion notification to distinguish the characteristics of packet losses;at the same time,the sender took advantage of the monitor result to adjust the TCP segment size.The simulation results show that the throughput of modified of TCP outperforms TCP_SACK and TCP_Reno by 100% approximately when the bit error rate is 1E-4.
