ARROW-WTCP: A Fast Transport Protocol Based on Explicit Congestion Notification over Wired/Wireless Networks

The inefficiency of legacy transmission control protocol (TCP) over wired/wireless networks inspired numerous research results in recent decade. To design a congestion control protocol that can achieve strong stability, fairness, fast convergence and high-utilization in hybrid networks, we propose AcceleRate tRansmission towards Optimal Window size TCP for Wireless networks (ARROW-WTCP) by providing a joint design of source and router algorithms, which enables feasible deployment of ARROW-TCP from wired to wireless networks. In our experimental study, we compare ARROW-WTCP with eXplicit Control Protocol Blind (XCP-B), the wireless version of XCP. Simulation results show that ARROW-WTCP outperforms XCP-B in terms of stability, fairness, convergence and utilization under highly dynamic wireless networks.
