Chunlei Liu, Raj Jain, "Using Congestion Coherence to Enhance TCP over Wireless Links," OSU Technical Report, June 2001.


It is well known that TCP has low performance over wireless links. With the rapid development of wireless and mobile communications, there is a pressing need to enhance TCP performance over wireless links. In the past few years, a number of enhancements have been proposed. In this paper, we review these proposals and analyze the degradation of TCP performance due to errors in the wireless link. We propose an enhancement that meets several desirable requirements and relieves TCP from all degradations caused by wireless errors. Simulation results and analysis show this enhancement works much better than other enhancement proposals for all ranges of wireless error rates.
