Abstract: Computation of efficient paths is very much essential for Mobile Ad hoc Networks (MANETs) due to frequent topological changes. In the context of IoT, MANETs could represent scenarios such as military applications, disaster recovery operations etc. In AODV, since at a time only one path is identified, due to link or node failure the current path becomes invalid. In AOMDV, the paths that are existing in the routing table are not node disjoint. i.e., whenever link or node failure occurs in the network, the current path becomes invalid. In this work, route discovery of the original AODV is altered by using the path accumulation feature of DSR to compute multiple paths. Among these, only node disjoint paths are selected using the path matrix method. The modified Multipath QoSe Aware Routing Protocol (MQARP) is compared with the original AOMDV. The proposed MQARP performs better in terms of delay, PDR and control overhead.
