TCP congestion control works well in wired Internet network but it is difficult to determine a good congestion window in a heterogeneous wireless network that consists of the wired Internet and various types of wireless networks. Therefore, we propose herein a novel adaptive window congestion control, namely TCP-Taichung, for TCP connections in heterogeneous wireless networks. The proposed RTT-based congestion control is designed for the Slow Start, Congestion Avoidance, Fast Retransmit and Fast Recovery phases to increase throughput while supporting high fairness. In addition, an optimal shrink factor is proposed to determine the optimal cwnd and ssthresh for the cases of network congestion or wireless-link error. Numerical results demonstrate that TCP-Taichung outperforms other approaches in goodput and fairness under various wireless network topologies. Especially, in the case of 10% packet loss rate in wireless link, the proposed approach increases goodput up to 200% as compared with NewReno.
