A Novel Approach to Find an Optimal Path in MANET Using Reactive Routing Protocol

If there is no communication between the nodes in MANET, reactive protocols don’t preserve routing information in the network node level. Reactive protocol determines a route to a specific destination when a particular packet intends to send. We propose a reverse reactive routing based Route discovery approach, which is used to find an optimal route to the destination with lower overhead, than the flooding based reverse route discovery. We also showed that the process of the reverse reactive protocol performance for finding an optimal path to the destination. The discussion is based on the optimal path, which is obtained through three steps; those are reverse route calculation in route request (RREQ), reverse route calculation in route reply (RREP) and reverse route calculation in route error (RERR). Experiments have been carried out using NS2 as network simulator and results show that performs better than reactive routing protocol (AODV).
