Throughput Maximization in Multi-channel Wireless Mesh Access Networks

The throughput maximization problem of wireless mesh access networks is addressed. For the case of cooperative access points, we present a negotiation-based throughput maximization algorithm which adjusts the operating frequency and power level among access points autonomously, from a game-theoretical perspective. We show that this algorithm converges to the optimal frequency and power assignment which yields the maximum overall throughput with arbitrarily high probability. Moreover, we analyze the scenario where access points belong to different regulation entities and hence non-cooperative. The long-term behavior and corresponding performance are investigated and the analytical results are verified by simulations.
