The multi-channel multi-radio technology represents a straightforward approach to expand the capacity of wireless mesh networks (WMNs) in broadband wireless access scenarios. However, the effective leveraging of this technology in WMNs requires (i) enhanced MAC protocols, to coordinate the access to multiple channels with a limited number of radio interfaces, and (ii) efficient channel allocation schemes, to mitigate the impact of co-channel interference. The design of channel assignment schemes and MAC protocols is strictly interrelated. On the one hand, the medium access delay depends on the number of potential interferers which are allocated on a given channel. On the other hand, channels can be allocated based on link–layer metrics. Joint design should be considered to optimize the mesh network performance. In this paper, a Channel Assignment and Fast MAC Architecture (CAFMA) is proposed …
