Performance Analysis of MANET Routing Protocols over Different Mobility Models

This work is a simulation based comparison of three Mobile Ad Hoc Networks (MANETs) routing protocols – Destination Sequenced Distance Vector (DSDV), Ad hoc on demand Distance Vector (AODV) and Dynamic Source Routing (DSR). The comparison is based on their performance in some existing mobility models used in the simulation of MANETs. The mobility models used in this work are Random Waypoint, Manhattan Grid, Gauss-Markov, Reference Point Group and Heterogeneous Mobility Models. With detailed simulations of the protocols across these models, comparisons are made based on results obtained using known metrics for evaluating the protocols. Also, the protocols are compared under varied categories of disaster area scenarios modelled by a Heterogeneous mobility model. Across the models with respect to considered metrics for comparison, DSR outperformed others followed by AODV and then DSDV
