“…Static Assignment (Kyasanur and N.H. Vaidya, 2005): In this approach a channel is assigned to an interface either permanently or over long periods of time. This approach is further sub-divided into two subclasses -(a) Common channel approach and (b) Varying channel approach.…”

“…Dynamic Assignment (Kyasanur and N.H. Vaidya, 2005): This approach offers the advantage of using different channels per radio interface so as to result in a high throughput. However, the drawback of this approach are (i) that a node that is communicating with another node needs a coordination mechanism to inform the other node of when to switch the channel and to what frequency to switch to (ii) this feature has to be carefully designed to avoid instability that would happen when a network never converges and endlessly circles between different channel assignments.…”

“…Hybrid Assignment (Kyasanur and N.H. Vaidya, 2005): This approach combines the strategies of static and dynamic assignment -static assignment is done for some interfaces and a dynamic assignment for other interfaces. A further classification is formed based on if the interfaces that adopt a static assignment use a common channel or a varying channel approach.…”

Abstract:An algorithm for self-organisation that assigns the channels intelligently in Multi-Radio Wireless Mesh Networks (MR-WMN) is important for the proper operation of MR-WMN. The aim of the self-organisation algorithm is to reduce the overall interference and increase the aggregate capacity of the network. In this paper, we have first proposed a generic selforganisation algorithm that addresses these two challenges. The basic approach is that of a distributed, light-weight, co-operative multiagent system that guarantees scalability. Second, we have evaluated the performance of the proposed self-organisation algorithm for two sets of initialisation schemes. The initialisation process results in a topology control of MR-WMN by way of spatial distribution of connectivity between the mesh nodes. The results have been obtained for realistic scenarios of MR-WMN node densities and topologies. We have shown further the need to develop non-transmit power control based algorithms to achieve a further increase in system capacity.

Abstract-The focus of this paper is on wireless mesh networks. In particular, we study the multi-radio case, given the considerable improvement in network throughput that multiple radios allow to achieve and the availability of cost-effective wireless devices. Interesting research problems are still unsolved in this field. Due to the scarcity of non-overlapped frequency channels and available radios per node, interference is still present, which cuts the achievable throughput down. As interference depends on how channels are bound to radio interfaces, a proper channel assignment scheme is needed to reduce the interference.In this paper we identify some key requirements of a channel assignment scheme. Accordingly, a centralized channel assignment algorithm is developed for multi-radio wireless mesh networks in order to maximize the throughput and address the interference problems. Finally, a performance study is presented to assess the effectiveness of our proposed algorithm.
