The Ad-hoc On-demand Distance Vector (AODV) is a routing protocol designed and best suited for mobile ad hoc network. Most of the on demand routing protocol including AODV use single route reply along the reverse path. Due to rapid changes of topology the route reply may not arrive to the source node resulting in sending several route request messages and degrading the performance of the routing protocol. The extended AODV called Reverse Ad-hoc On-demand Distance Vector (R-AODV) protocol uses a reverse route discovery mechanism and performs well when link breakage is frequent.
