WXCP: Explicit Congestion Control for Wireless Multi-hop Networks

Abstract. TCP experiences serious performance degradation in wireless multi-hop networks with its probe-based, loss-driven congestion control scheme. We describe the Wireless eXplicit Congestion control Protocol (WXCP), a new explicit flow control protocol for wireless multi-hop networks based on XCP. We highlight the approaches taken by WXCP to address the difficulties faced by the current TCP implementation in wireless multi-hop networks. Simulations with ns-2 show that WXCP outperforms current TCP implementations in terms of efficiency and fairness.
