Abstract

Vehicular Ad hoc Network (VANET) is very promising technique to increase traffic safety. This will help in saving life of many people from road accidents. VANET uses vehicle to vehicle communication to inform about the location of other vehicles and the traffic density. There are many routing protocols described in VANET. Position-based protocols are best suited in highly dynamic topology environment as followed by VANET. We will compare various position-based protocols on bases of various parameters. The advantages and limitations of these protocols are also discussed. We also summarized some protocols, which consider real time communication traffic and compare them with other well-known position based protocols.
