A Novel Multipath Routing Scheme in Mobile Adhoc Networks
Mobile adhoc network is a set of mobie devices that can communicate with each other without infrastructure. The reactive protocols use a flood-based discovery mechanism to find routes when required. Since each route discovery incurs high overhead and latency, the frequency of route discoveries must be kept low for on-demand protocols to be effective. Multipath on-demand routing protocols can achieve better performance and scalability because in the single route discovery process it will find out the several routes. This paper proposed a novel multipath routing scheme which is used to reduce the routing overhead by using derived paths. The multipath routing scheme calculates fail-safe multiple routes and gives all the in between nodes of the prime path with several paths to target node. Simulations show that the performance of proposed approach is better than the conventional AODV.
