With the increasing demand on high quality wireless broadband access service, the traditional access technologies become inadequate. As a new and promising next generation network, wireless mesh network draws researchers’ attention by its advantages of large coverage, low deployment cost, convenient access and so on. In this paper, we research on the performance of channel allocation scheme in IEEE 802.11s WMN. The property of the traditional fixed assignment algorithm and the mesh interference model are discussed. Then an improved channel allocation scheme based on these will be introduced and implemented. The simulated performance of the new improved algorithm will be shown as the result.
