A Topology Control-Based Self-Organisation in Wireless Mesh Networks

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 self-organisation algorithm that addresses these two challenges. The basic approach is that of a distributed, light-weight, cooperative 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 in addition the need to develop non-transmit power control based algorithms to achieve a further increase in system capacity

Performance Evaluation of a Self-Organising Scheme for Multi-Radio Wireless Mesh Networks

Multi-Radio Wireless Mesh Networks (MR-WMN) can substantially increase the aggregate capacity of the Wireless Mesh Networks (WMN) if the channels are assigned to the nodes in an intelligent way so that the overall interference is limited. We propose a generic self-organisation algorithm that addresses the two key challenges of scalability and stability in a WMN. The basic approach is that of a distributed, light-weight, co-operative multiagent system that guarantees scalability. The usefulness of our algorithm is exhibited by the performance evaluation results that are presented for different MR-WMN node densities and typical topologies. In addition, our work complements the Task Group 802.11s Extended Service Set (ESS) Mesh networking project work that is in progress

Evaluation of a self-organization scheme with topology control in mesh networks

Mesh networks with an autonomous channel assignment can be used as a viable cost-effective alternative for a last mile broadband access. The channel assignment algorithm in mesh networks should be capable of reducing the overall interference in it. In this paper we have: (i) summarized the usefulness of our algorithm by drawing a comparison between the key features of our self-organization scheme with those of other significant schemes in literature, (ii) proposed a process for initiating the topology of self-organized mesh networks (iii) evaluated the impact of the initialization process on the performance of the self-organization algorithm for realistic scenarios with different mesh node densities and topologies

Impact of Topology Control on the Performance of a Self-Organization Scheme for Wireless Mesh Networks

Multi-radio wireless mesh networks (MR-WMN) with a smart channel assignment scheme can be used as a viable cost-effective alternative for a last mile broadband access. The channel assignment algorithm should be such that it reduces the overall interference and increases the aggregate capacity of the network. In this paper, we have concisely presented the key results of our work in progress, which pertain to the evaluation of self-organization algorithm for multi-radio mesh networks. Specifically, the study focuses on the impact of initialization process on the selforganization algorithm performance as it involves mesh node selection for channel assignment. The initialization process results in a topology control of MR-WMN by way of spatial distribution of connectivity between the mesh nodes. The process for initiating the topology of selforganized mesh networks is also described. In order to conclusively show the merits of our initialization process, we have carried out this study for realistic densities of the mesh nodes and their topologies varying from completely random to being ordered in a grid
