We propose a new congestion control mechanism to improve network performance. It is based on the end-to-end receiver centric method, and adopts both the rate-based and the window-based functions. The available bandwidth is measured at the receiver and the sending rate is adjusted based on the measured bandwidth. The advantages of our mechanism are accurate bandwidth estimation, reduced timeout, and better utilization of bandwidth and buffer. Since it can distinguish wireless packet losses from congestion packet losses, it helps to improve the poor performance in a wireless environment. We also provide a model to analyze our mechanism in wired networks with multiple connections and prove that our mechanism can improve the throughput performance of TCP greatly. Our simulation results in various scenarios validate that our mechanism can improve throughput and fairness performance in both wired and wireless networks by resolving the few problems of TCP mechanism.
