Urban-X: Towards Distributed Channel Assignment in Cognitive Multi-Radio Mesh Networks
Researches about multi-radio mesh networks have mostly focused on channel allocation under internal interference. However, the deployment of WMNs in unlicensed bands of dense urban areas imposes many challenges regarding co-existence with residential access points. In this paper, the authors propose Urban-X, which is a first attempt towards a new architecture for Multi-Radio Cognitive Mesh Networks. They develop a novel channel assignment that reflects channel and residential traffic state of external users to maximize network throughput. They evaluate their approach using an enhancement of the ns-2 simulator.
