Improving TCP Performance in Hybrid Networks
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. TCP is the most dominant transport protocol that serves as a basis for many other protocols in wired and wireless networks. However, high transmission errors and varying latency inherent in wireless channel would have a seriously adverse effect on the performance of TCP. Thus, a novel and pragmatic 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. The proposed design indeed provides a more efficient solution for frequent transmission loss by setting optimal congestion window to improve TCP performance in multi-hop network.
