As there is a growing need for the cost effective and highly dynamic large-bandwidth networks over large
coverage area , the Wireless Mesh Network provide first step towards effective communication. A Wireless
Mesh Network is one of the most advanced wireless network used for communication. During their
operating period , the wireless mesh network may suffer from frequent link failure which results in poor
performance of network. Link failure detection plays crucial role in performance of WMN. The proposed
paper presents the review of various techniques used for detection of link failure and the techniques used
for recovery of wireless mesh network.
