Abstract:

The channel assignment problem can heavily impact the performance of multiradio multichannel wireless mesh networks. Many channel assignment algorithms are proposed, whereas most of them need the whole network topology or the flow model, which is hard to obtain in the distributed networks. Based on the above analysis, in this paper, we propose the local information based channel assignment (LICA) strategy, which means, by using the heuristic information of local topology and channel usage of all the neighborhood nodes, it allocates the channel resources on each node dynamically. The result shows that algorithm LICA can significantly improve the endtoend throughput and channel utilization in lower time complexity and also has better expansibility.
