A Survey On Fault Tolerance In Wireless Mesh Network

Since WMNs are typically used as wireless backbones, they have the nature that the wireless communication is not constant. Hence, it is important to defend them against link or node failures, hence a fault tolerant network is needed. Lot of work has been done on the link failures but base station failure has not been covered by much of the researchers. So in our paper we are discussing some of the approaches taken in mind by many researchers for managing base station failures and link failures. As WMN is used in many applications of networks, we have to find the solutions necessarily for making it fault tolerant. The researchers should focus on the requirement for making a strong backbone network. Our paper will be lightening the areas not covered so far in WMN for dealing with base station failures. Our paper is presenting a survey report on the comparison of various strategies used for handling base station failures and link failures. It also provides an outline as to how to recover from failures. Keywords-componentwireless, network, fault, tolerance, failure, base station.
