A method and study of topology control based self-organization in mesh networks

An algorithm for self-organization 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-organization algorithm is to reduce the overall interference and increase the aggregate capacity of the network. This can be possible by addressing the two major challenges that are associated with the selforganization of MR-WMN" Scalability and Stability. In this paper, we have first proposed a generic self-organization 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-organization algorithm for two sets of initialization schemes. The initialization 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.
