Performance Enhancement of SACK TCP Protocol for Wireless Network by Delaying Fast Recovery
by N.J. Kothari and K.S. Dasgupta in the Proceedings of the International Conference on Wireless and Optical Communications Networks, 2006


Last few years have shown brisk intensification in Internet over the entire globe with heterogeneous networks. Hence the effectiveness of most important & inseparable part, TCP/IP protocol suite, plays a significant role. Wireless links involved in the formation of heterogeneous network is facing serious problems of random BER (Bit Error Rates) which causes random loss. The older TCP (Transmission Control Protocol) was designed for wired links, where the cause of packet loss was due to congestion only. The same protocol policies were incorporated in TCP/IP model with least changes initially. As this was unable to differentiate between losses due to congestion and due to corruption (BERs-random loss), it became the main cause of performance degradation of TCP on wireless links. This paper explores the way to add intelligence in TCP by modifying it to improve data rate in case of random losses which occur on wireless link frequently. Scenarios used to test algorithm are experiencing congestion and corruption loss individually as well as together. Standard BERs are used to measure performance. Modified protocol shows great performance improvement over unmodified in case of random loss as well as shows compatibility with an unmodified protocol in case of congestion loss only.
