In recent years, on-demand routing protocols have attained more attention in mobile ad hoc networks as compared to other routing schemes due to their abilities and efficiency. There exist many on-demand routing protocols for Mobile Ad hoc NETworks (MANETS). Most of the protocols, however, use a single route and do not utilize multiple alternate paths. Multipath routing allows the establishment of multiple paths between a single source and single destination node and when a path breaks an alternate path is used instead of initiating a new route discovery, hence multipath routing represents a promising routing method for wireless mobile ad hoc networks. Multipath routing achieves load balancing and is more resilient to route failures.
