Abstract: Aiming at the capacity problem in multi-network interface card，multi-channel wireless mesh network，based on wireless channel interfere model and wireless nodes’ transmission power to be given in physical layer，a cross-layer union optimization algorithm is proposed by jointing rate control in transport layer，routing algorithm in network layer and channel assignment in MAC layer，and using the strategy of executing routing computation twice in the paper.Simulation results show that the network throughput can be improved significantly by the proposed algorithms.
