MANET (Mobile Ad-Hoc Network) is an independent collection of mobile nodes that communicate over quite bandwidth constrained wireless links. In Mobile Ad hoc Networks (MANETs), the performance of various on-demand routing protocols significantly affected by the changing network topology.in the route discovery process, AODV (Ad-hoc On-Demand Distance Vector) is the mostly studied on-demand routing protocol that uses single route reply packet with reverse path for answering to the source node. Due to increase in the variability of the network topology, the possibility of route reply packet loss increases & destroys the performance of the routing protocol. It includes related material and details of other modified AODV protocols like R-AODV, Multipath Routing Protocol. This protocols makes better performance as compared to AODV but there we need more modification for efficient. We then focus on the end-to-end delay, throughput and overhead for the performance improvement. As by, we proposed a new AODV routing protocol that uses R-AODV for route discovery and Multipath routing protocol for data(packet) sending from source to the destination. Our proposed Protocol (P-AODV) would improve performance in terms of Average End-to-End Delay, Throughput and Routing Overhead.
