An overview of channel assignment methods for multi-radio multi-channel wireless mesh networks
2010
Channel Assignment (CA) is an active research area due to the proliferating deployments of multi-radio multi-channel wireless mesh networks. This paper presents an in-depth survey of some of the CA approaches in the literature. First, the key design issues for these approaches are identified, laying down the basis for discussion. Second, a classification that captures their essentials is proposed.

Channel allocation in multi-channel wireless mesh networks
In this article, we survey the latest progress in multi-channel wireless mesh networks, focusing on wireless interference models and channel allocation algorithms with the goal of maximizing the network performance. We present the studies of different interference models and illustrate how they could affect the design of channel assignment. We also summarize channel allocation algorithms with different strategies in both omni-directional and directional antenna networks. We conclude that both static and dynamic channel allocation strategies have advantages and disadvantages, and the design of channel allocation algorithms strongly depends on the interference model and the assumption of network traffic.

Channel Assignment in Multi–Radio Wireless Mesh Networks
With the increasing usage of Wireless Mesh Networks, improving their performance is a very active research field. The use of multiple radio interfaces is particularly suited to these networks, but requires spreading the communication on different channels to avoid overcrowding the spectrum. Strategies on how to efficiently perform the channel assignment to the different radio interfaces are not trivial, especially when the traffic patterns are taken into account. This report presents an analysis of recent research in the field, and identifies the most promising approaches while pointing out limitations and directions of future research.

Wireless mesh networks (WMN) have arose as a technology for subsequent generation wireless networks due to its cost effectiveness and effortless deployment. The performance of wireless mesh networks can be considerably improved by multi-channel communication. The existence of interference confines the use of channel assignment in wireless mesh networks.The significance of inter-flow and intra-flow interference is ignored in existing solutions, so the information is erroneous leads to inaccurate bandwidth estimation and reservation. All the techniques to measure interference is measurement based that not holds good for practical applications.This approach proposes a distributed and polynomial-time heuristic channel assignment to minimize interference in WMNs. Inchannel allocation route delay restriction is measured to avoid every node on the tree interfering with several other nodes. Packettransmission will be affected by this interference. There will be a huge delay in packet transm...
