In a wireless Mesh network, to minimize interference within the mesh network to improve network connectivity, a kind of greedy heuristic algorithm based on predicting traffic was proposed, which can minimize the link interference and predict the channel traffic in this cycle time based on the channel traffic of the last cycle time. In the course of the specific channel allocation, the channel with larger estimated value has the priority to be assigned. Simulation results showed algorithm proposed can ensure the traffic in each link can be kept balanced within the network in a certain period of time and reduce the waiting time while a data frame is transmitting. Then the network throughput can be increased and the transmission performance can be improved.
