Autonomously recover from wireless link failure through 'Autonomous Network Reconfiguration System' (ARS) with multi-radio in WMN

Literature Review from the year 2018 in the subject Computer Science - Software, , language: English, abstract: This paper describes the technique to recover from the failures that occurs in Wireless Mesh networks(WMN) like node failure, link failures etc, due to channel interference, dynamic obstacles or application bandwidth demands. 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. ARS has been implemented and evaluated extensively on our IEEE 802.11-based WMN test-bed as well as through ns-2-based simulation. By using channel and radio diversities in WMNs, ARS generates necessary changes in local radio and channel assignments in order to recover from failures. Next ARS's on-line reconfigurability allows for real-time failure detection and network reconfiguration, thus improving channel-efficiency by 92%. Our evaluation results demonstrated the effectiveness of ARS in recovering from local link-failures and in satisfying application's diverse QoS demands.
