Abstract: Mobile Ad hoc Network (MANET) are wireless networks consisting of a collection of mobile nodes with no fixed infrastructure. Since mobile ad hoc networks change their topology frequently, routing is one of the challenging task. To avoid frequent route discovery and link failures, various multipath routing protocol has been proposed based on the existing single path routing protocol in ad hoc networks. Ad hoc On-demand Multipath Distance Vector (AOMDV) is one of the well-known multipath protocol which extends the prominent Ad hoc On Demand Distance Vector (AODV) to discover multiple link-disjoint paths between the source and the destination. In this paper, we survey on various protocol which improvise and modify AOMDV protocol in order to resolve various issues like route cut-off, energy efficiency and helps to achieve better performance.
