Abstract: Motive of this research paper is to develop multiple route discovery mechanism which can not only enhance scalability but also reduce transmission time with AODV MANET routing protocol. A modified AODV Protocol algorithm is developed in this paper which will attempt to discover several paths to a destination node in a single route discovery. To validate and verify this algorithm, simulations are performed on base version of AODV and modified version i.e. AMR-AODV. Results of simulations are compared and analyzed based on evaluation of various parameters like Packet Delivery Ration, Routing Overhead, Number of Nodes, Terrain Range, Mobility Speed and Mobility Model used. This research paper comes to the conclusion that AMR-AODV is a s much better performer in certain scenarios as compared to base AODV, which AODV still remains better in some conditions.
