Autonomously Reconfiguring Failures in Wireless Mesh Networks

Wireless mesh networks (WMNs) are being developed actively and deployed widely for a variety of applications They have also been evolving in various forms to meet the increasing capacity demands. However during their lifetime, multi hop wireless mesh networks (WMNs) experience frequent link failures caused by channel interference, dynamic obstacles, and/or applications’ bandwidth demands. These failures cause severe performance degradation in WMNs or require expensive manual network management for their real-time recovery. This paper presents an autonomous network reconfiguration system (ARS) that enables a multi radio WMN to autonomously recover from local link failures to preserve network performance. By using channel and radio diversities in WMNs, ARS generates necessary changes in local radio and channel assignments in order to recover from failures. In addition, to strengthen its performance, this paper concentrates on avoiding the failures by setting up a threshold limit, which would eventually enhance the performance.
