Abstract- MANETs has mobile nodes which are connected through dynamic multi-hop channels. Routing in MANET is a difficult task which has received much attention from researchers. Consistent link failures occur in mobile ad-hoc networks because of node’s mobility and use of fickle wireless channels for data transmission. Because of this, multipath routing protocols arrive with a critical research issue. In this, we propose to implement node-disjoint multipath routing based on AOMDV protocol. The main objective of proposed approach is to obtain all available node-disjoint routes from source-destination with minimum delay and high throughput. With this given approach, as first route for destination is dogged the source starts data transmission. All other backup routes, if available, via the first route are scheduled concurrently with data transmission. In the current work we are proposing the concept of Node Disjoint–Multipath based on the congestion threshold and results will be obtained through various simulations shown via the effectiveness of our suggested methods in terms of End to end delay, Throughput, hop count, Packet delivery Fraction
