摘要：The IEEE 802.11s Wireless Mesh Networks (WMN) is a new multi-hop technology increasing the coverageof IEEE 802.11 Wireless Network and providing Internet access. In order to increase the mesh networkcapacity, the WMN has evolved from single-radio single-channel architecture to Multi-Channel Multi-Radios (MC-MR) architecture. In MC-MR the main challenge of the WMN is the channel assignment. Inthis article, we propose a new channel assignment method based on channel diversity. This new methodnamed ODCAM (On Demand channel Assignment Method for channel diversity ) defines a channeldiversity mechanism used to select a new channel along the path between the source and the destination.The best path between the source and the destination is provided by the HWMP (Hybrid Wireless MeshProtocol) protocol using MWCETT (Modified Weighted Cumulative Expected Transmission Time) anextension of the WCETT metric. The simulation results show the ODCAM performance compared with anhybrid approach.
