A Channel Assignment Algorithm Based on Link Traffic in Wireless Mesh Network

In a wireless mesh network, in order to accomplish the purposes of minimizing the interference within the mesh network and improving the network connectivity in the course of channel assignment. This paper proposed a heuristic algorithm which can predict the busy-degree of a node through predicting the link traffic in the networks. So the algorithm can respond to the distribution of data traffic flexibly. This paper also used the protocol interference model to reduce the interference between the links in the wireless mesh network. Simulation results show that the algorithm can reduce the waiting time while a data frame is transmitting. And the network throughput and stability can be improved significantly.
