QARS for Self Reconfiguration Mechanism in Wireless Mesh Networks
Journal Title: International Journal of Advanced Research in Computer Engineering & Technology(IJARCET) - Year 2013, Vol 2, Issue 2
Abstract
Wireless mesh networks (WMNs) are being developed actively and deployed widely for a variety of applications. Wireless Mesh Network (WMN) is a communication network made up of radio nodes organized in a mesh topology. Mesh Network has the advantages of fast implementation, easy maintenance and low direct investment while comparing with the existing networks. Multi-hop wireless mesh networks (WMNs) experience frequent link failures due to channel interference, dynamic obstacles, and bandwidth demands. These failures cause severe performance degradation in WMN. This paper proposes a Quick Autonomous Reconfiguration System (QARS) that enables a multi-radio WMN to autonomously recover from local link failures. QARS first searches for feasible local configuration changes available around a faulty area, and identifies reconfiguration plans that require the minimum number of changes for the healthy network settings. QARS using enhanced bully algorithm for leader node selection helps in times of link failures in the network.
