Improving 802.11 wireless TCP performance with adaptive Reed-Solomon codes: An experimental study
TCP is currently the dominant protocol for the Internet having originally been designed to perform congestion control and flow control in wired networks. Recently, wireless LAN has been very successful in extendingg the connectivity of the Internet. However, the performance of TCP in the wireless environment is worse than that in the wired one. Furthermore, the error rate changes with the time in the wireless environment due to EMI, movement, or auto-rate-selection. Especially, the popular 802.11 wireless LAN does not employ any FEC or ARQ to improve error rate performance. In order to improve the wireless TCP performance, TCP with adaptive Reed-Solomon codes (ARSC) is proposed. The performance of the proposed TCP with ARSC is verified by simulations and experiments in the test bed.
