Abstract
The performance of TCP over wireless links could degrade due to handoff, high bit error rate and long roundtrip delay on the air interface. The conventional Radio Link Protocol uses fixed channel coding and ARQ to mitigate impairment over wireless channels. Adaptive channel coding with the use of punctured convolutional codes has been proposed for its ability to adapt to channel quality and maintain a high level of system throughput. In this paper, we study TCP over adaptive RLP based on estimated channel condition. We consider a Markov channel model and evaluate the performance of TCP with adaptive RLP in such environment. We also evaluate the existing channel quality measurement in wireless systems and propose a methodology to update RLP channel coding schemes based on filtered channel measurement. We use simulation to calculate the throughput of TCP system and determine the effectiveness of adaptive channel coding with respect to different fading rates.
