In recent years, the number of vehicles has been increasing enormously, this growth has led to an increase in the possibility of accidents. To overcome this situation and to make the driving experience enjoyable, and more comfortable, a special technology based on the Mobile Ad-hoc wireless network infrastructure (MANET) has appeared on the surface. Such technology is called Vehicular Ad-hoc Networks (VANETs). It allows vehicles to communicate with each other or communicate via infrastructure to exchange different kinds of information and warning messages. Scientists and programmers have developed VANET simulation programming to enable the examination and evaluation of various media access, routing, and crisis alerting protocols. In this paper, a short survey is pursued on some common simulators that can be applicable in VANETs. Because such platforms can save a lot of money and time, as well as make the simulation process more realistic; OMNeT++ and SUMO are both used together to investigate the VANET environment using a road traffic simulation. The simulation results obtained can draw a good and helpful guideline in developing VANET performance through its routing protocols.
