In this paper, the authors represent a simulation based comparison of two variants of a MANET routing protocol viz. ad-hoc on-demand distance vector. Simulation is through network simulator 2.35. Packet delivery ratio, average end to end delay and throughput have been used as comparison matrices. Simulation results shows, that AOMDV performs almost equivalent to AODV in terms of packet delivery fraction. The paper also proves that for the given scenario AODV will be a better choice for a time-constrained network application.
