The study of routing strategies in vehicular ad-hoc networks

Vehicular ad hoc networks (VANETs) are a particular category of mobile ad hoc networks (MANETs) characterized by a high mobility and a reduced connectivity. As a prerequisite to communication, an efficient route between network nodes must be established, and it must be adapt to the rapidly changing topology of vehicles in motion. This is aim of VANET routing protocols. The simulation scene was set up by means of the NS2 simulation platform in this paper. The performances of ad hoc on-demand distance vector (AODV) and dynamic source routing (DSR), two classical routing protocols of MANET and VANET, are simulated and analyzed, and the conclusion that the AODV protocol is more suitable for VANET than the DSR protocol is derived.
