Mobile ad hoc network is the multi-hop wireless network, MANET does not require any kind of cellular infrastructure, and provides node mobility frequently. Due to the mobility of the nodes made changes frequently in a network topology, and to manage such changes is challenging task in MANET. The advantage of multi-path routing in MANETs is not obvious because the traffic along the multiple paths will interfere with each other. In this paper, the Ad Hoc On Demand Multipath Distance Vector (AOMDV) routing protocol is used for mobile ad hoc networks has been trying to improve the protocol to provide availability of path, and this proposed work suggested three changes in MANET one on a protocol based and two on topology based changes if we made some changes in it may change the definition of Ad-Hoc network and MANET. This is a totally new approach for ad-hoc and MANET, because in ad-hoc network is infrastructure less.
