Modeling and Simulating Network Connectivity in Routing Protocols for MANETs and VANETs
In this paper, the authors present a framework for node distribution with respect to density, network connectivity and communication time. Using NS2, they evaluate and compare performance of three routing protocols; Ad-hoc On-demand Distance Vector (AODV), Dynamic Source Routing (DSR) and Fisheye State Routing (FSR) both in MANETs (IEEE 802.11) and VANETs (IEEE 802.11p). They further enhanced these protocols by changing their routing information exchange intervals; MOD AODV, MOD DSR and MOD FSR. A comprehensive simulation work is performed for the comparison of these routing protocols for varying motilities and scalabilities of nodes. As a result, they can say that AODV outperforms DSR and FSR both in MANETs and VANETs.
