Abstract

In this paper, the problem of multi-flow opportunistic routing in lossy wireless mesh network is considered. A heuristic algorithm, named MulSrc, is proposed. Building on backpressure scheduling and intra-flow network coding, MulSrc eliminates coordination between node as well as improves the fairness in rate allocation between different flows. To adjust the sources' upper layer rate to network condition, a TCP-like rate control mechanism is adopted, which makes MulSrc suitable for delay-sensitive but loss-tolerant applications, such as adaptive audio/video streaming. Simulation results demonstrate that MulSrc outperforms both a single-path backpressure routing algorithm that uses jointly optimal routing and flow-control approaches and the classical opportunistic routing algorithm MORE.
