Wireless Mesh Network (WMN) is one of the essential elements in the networks of the future because of its ability to provide high bandwidth wireless backbone covering a large physical region. Generally single radio mesh nodes operating on a single channel suffer from capacity issues and hence it is essential to equip mesh routers with multiple radios using multiple non overlapping channels. But during their lifetime, multi radio wireless mesh networks suffer from link failures caused by channel interference, dynamic obstacles, and applications bandwidth demands. This paper presents a detailed analysis of various reconfiguration techniques used to recover wireless mesh network from link failures and the issues to be addressed in order to maximize the network performance.
