A Vehicular Ad hoc NETwork (VANET) is emerged as new technology to communicate between vehicles without using infrastructure. The characteristics of VANET are high mobility and rapid change of topology, so the routing protocols affected by the rapid changes and symmetric link break. This paper evaluates three routing protocols: AODV, OLSR and DYMO, by analyzing the performance of these routing protocols using two different MAC protocols IEEE 802.11p and IEEE 802.11g. As well as, two different scenarios are considered (highway and city) to measure and evaluate the performance of routing protocols by varying the number of vehicles, vehicles speed using OMNeT++ as network simulator Simulation Urban MObility (SUMO) as a traffic simulator.
