Survey of Router Link Failure Detection in Wireless Mesh Network

Abstract: Routers are small electronic devices that join multiple computer networks together via either wired or wireless connections. A tree topology is used to construct a wireless sensor network for data delivery applications. Data delivery failures occur in the form of mobile node movements and topology changes. To increase the data delivery ratio and mitigate the effects of packet loss caused by the mobile nodes. A wireless mesh networks is one of the most advanced wireless network, used for the wireless communication. Wireless network may suffer from frequent link failure which degrades the network performance. The proposed survey paper presents the review of the various detection techniques used to recover the router link failure in Wireless Mesh Network.
