TCPW-REAL: TCPW enhancement for wireless networks

Traditional transmission control protocol(TCP) works well in wired network but suffers from performance degradation in wireless networks.Due to the fact that it cannot distinguish packet losses due to congestion from packet losses due to link breakage,channel error and route changes.An enhanced TCPW,named TCPW-REAL,is proposed to improve the TCP performance in wireless networks.By modifying the algorithm of the ACKs,TCPW-REAL can make an accurate estimate of the bandwidth.Besides,a throughput model for TCPW-REAL is given,which is validated through simulation.It is shown by analysis and simulation that the pro-posed approach can greatly improve the TCP performance in wireless networks.
