Considering the channel dependence. this paper designs greedy algorithm in Multi-Channel Allocation joint scheduling and routing. Unlike the traditional multi-channel Wireless Mesh channel allocation, the proposed scheme considers scheduling and routing, and the network is divided into two states by network segmentation. The linear planning allocation method is used to minimize the average end-to-end delay for the maximum transmission link number for the total channel resource and routing scheduling problem for link consumption that adopt the integer linear programming method modelling, the greedy heuristic algorithm can be used. The simulation analysis shows that the algorithm of this paper can effectively improve the throughput of the network.
