It has been observed that TCP suffers from poor bandwidth utilization and extreme unfairness in wireless environment, and the utility of TCP in the multi-hop IEEE 802.11 network has been seriously questioned. The high transmission errors and varying latency in wireless channel would have a seriously adverse effect on the performance of TCP. Thus, a novel cross-layer approach with joint congestion and contention window control scheme and a probabilistic approach for RTT measurement is proposed to improve the performance of TCP in multi-hop networks.
