Abstract: MANET is an infrastructure less communication system. So have to face high challenges dynamically changing of topologies, low transmission power and asymmetric links. Due to link instability, node mobility and frequently changing topologies routing becomes one of the core issues in MANETs. A suitable and effective routing mechanism helps to extend the successful deployment of mobile ad-hoc networks. Most effort has recently been reported to improve reliability and performance of ad hoc network. So the multipath routing protocol has been implemented to achieve higher throughput and reliability than the current single path routing algorithm. Multipath extension of ad hoc on‐demand distance vector protocol can provide reliable and adaptable routes for communication. Many researchers are still working on the developments of MANET routing protocols. Simulation results show better performance in terms of Packet Delivery Ratio and Normalized routing Load in comparison to AODV routing protocol. The simulation work is verified using network simulator version 2. Keywords: AODV, Multipath AODV, MANET, NS-2.
I. INTRODUCTION The internet engineering task force created a mobile ad-hoc network Ad-hoc is a Latin word, which means "for this or for this only”. Mobile Ad hoc network is a group of wireless mobile nodes and connected by wireless links. It is a network of independent nodes, which are mobile, connected through the wireless medium and highly dynamic by nature, and exemplified by the absence of physical infrastructure. Each mobile node dynamically changes the network topology without relying on any wired backbone network or fixed base station [1-3]. The main purpose of an ad hoc network routing protocol is to enable the transport of data packets from one point to another. This work author examines the potential on the transport services which arise from the realization of nodes. The prerequisite of a routing service is a distributed mechanism for the discovery and maintenance of routes; network integrity and availability are required to ensure the correct operation of an ad hoc network. This work also provides a qualitative analysis of reactive protocols scope. Multipath routing can increase end-to-end throughput and provide load balancing in MANETs by the use of multiple paths. The concept of multipath routing motivated to design a multipath routing for mobile ad hoc networks. To avoid the overhead of additional route discovery attempts, minimize the routing overhead by the use of secondary paths and to reduce the route error transmission during route break recovery. The objective of designing a multipath routing protocol is to provide enhanced robustness to node or link failures. If one could provide multiple paths from a source to a destination, one could envision that the transmission of redundant information on various paths would help the receiver reconstruct the transmitted information even if a few of the paths were to fail. Single-path or link stability need to repair routes each time the route is broken, therefore these type of issues
