An Alternative Backup Route With a Loop Free Routing Table Short Distance in Adhoc Wireless

In a Mobile Ad hoc wireless NETworks (MANET), nodes communicate with each other via packet radios. However, in a MANET network, the mobility of the nodes and power limitations lead to an increased loss of connectivity between the mobile nodes when changing the route between nodes, which requires the routing table to be frequently updated. Hence, routing protocol plays an important role in updating the routing table when the nodes move from one area to another. By pre-computing a backup routing table in advance, the source can pass traffic through it without needing to wait for the routing table to be updated from where the failure occurs.
