Wireless Mesh Networks (WMNs) experience frequent link failures caused by channel interference, bandwidth demands causes severe performance degradation in WMNs .Link failure will lead to produce a sequence of disruptions to deliver the packets to the destination. To overcome this ART rerouting the traffic via an alternative path from a node whose local link is down without the need to wait until the source node knows about the failure. This is achieved by creating a new backup routing table based on the original routing table which is computed by the dijkstra algorithm. The goal of these algorithms is to reduce loss of packets, end-to-end delay time, improve throughput.
