Mobile Ad-hoc NETwork (MANET) is an infrastructure less network that is consisting of mobile nodes which communicate with each other via wireless links. This network is self-configuring, decentralized. In MANET's all participating nodes act as router and these nodes are free to move randomly. In MANET, transmission failure occurs due to several reasons, such as node mobility, energy deficiency. In multipath routing multiple routes will be discovered for a pair of source and destination. During communication when a primary path fails the secondary path will be selected without initiating new RREQ.
