    The aim of this paper is to present a novel multipath routing approach in MANETs as new extensions to AODV, a well-known traditional reactive routing protocol. The approach is called Threshold efficient Routes in multipath AODV (TRAODV) which is a link-disjoint multipath extension that tries to optimise routing delay overhead in the route discovery process of traditional AODV. The optimisation in TRAODV is accomplished by detecting the waiting time required for route reply procedure until receiving a threshold number of efficient routes. TRAODV is implemented and evaluated against two existing multipath extensions to AODV protocol; AOMDV and MRAODV, and two traditional multipath protocols; DSR and TORA. All protocols are implemented using NS2 and evaluated under the same simulation environment in terms of three performance metrics; packet delivery fraction, average end-to-end delay, and routing packets overhead. Simulation results show that TRAODV reduces the overall routing packets overhead compared to both extensions AOMDV and MRAODV, especially for large network size and high mobility.
