Efficient Optimal Route Stability Routing Protocol in MANET Using Gauss-Markov Mobility Model

In Mobile Ad-hoc Network (MANET), routing is the most important issue for communication. Numbers of routing protocols are available for communication in MANET, but optimality is the key issue in routing to improve the performance of MANET. Reactive protocols do not preserve routing information at the network node level, if there is no communication between the nodes. Reverse Reactive protocol determines a route to a specific destination when a particular packet is intends to send. We proposed an optimal route stability routing protocol based route discovery approach, which is used to find an optimal route to the destination with lower communication overhead than flooding based reverse route discovery mechanism. In this proposed work, Optimal Route Stability Routing Protocol (ORSRP) which is a reactive routing based approach uses the reverse route calculation in route request (RREQ), route reply(RREP), route cache (RCAC) and route error (RRER) in order to find out the optimal path. Extensive simulations have been carried out using NS2 network simulator and the obtained result shows that the performance of ORSRP is better than the other existing routing protocol.
