A solution for improving TCP performance over wireless links

Abstract

The integration and the implementation of Internet transport protocols over wireless networks has increasingly proven to be unavoidable. However, the environments over which wireless protocols act are very different from those found on wired networks. Several contributions were proposed to adapt the current protocols such as TCP to the wireless environment. The goal is to improve the performance of TCP over hybrid networks (i.e. wired networks together with wireless ones) without modifying or violating the semantics of these transport protocols. In this paper, we look at the problem from a different perspective than the solutions that were proposed in the past and come out with an original approach. After its simulation, our new protocol called FACK-TCP (for Forced Acknowledgment TCP), proved to be very promising. © 2003 by Springer Science+Business Media New York.
