Path Reconfigure in Wireless Mesh Network Using Extended ARS

Abstract

The Wireless Mesh Networks (WMNs) is one of the key components in the converged networks of the future, providing flexible high bandwidth over large geographical areas. Also that allowing multiple channels use in the same network is often presented as a possible way to improve the network capacity. During their lifetime, multihop 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 a network reconfiguration system and the path chages that enables a multiradio WMN to autonomously recover from local link failures to preserve network performance. By using channel and radio diversities in WMNs, reconfiguring system generates necessary changes in local radio and channel assignments in order to recover from failures. Next, based on the thus-generated configuration changes, the system cooperatively reconfigures network settings among local mesh routers. The system reconfigures with channel assignment, channel allocation, topology concepts etc.
