在多无线接口多信道的无线Mesh网络中，信道分配问题将影响网络的整体性能。为充分利用无线Mesh的资源优势，已提出了许多信道分配策略。然而，大部分的研究假设都隐含需要全网拓扑或者流量模型等信息，这在分布式网络中很难准确获取。为此，本文提出基于局部信息的自适应信道分配策略LICA，在仅使用局部拓扑和节点间信道使用情况等启发式信息的基础上，动态指导信道分配。模拟实验结果表明，LICA算法能显著提高信道利用效率和端到端的数据吞吐量，且具备较低的时间复杂度和良好的可扩展性

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.
