VANETS is the most popular network which is called Vehicular Ad hoc NETwork. The researchers make a lot of work in this network. From the literature review, VANETs works on the basis of real time system where the vehicles are moving nodes and travel with a very high speed on the roads in the urban areas. There are many security issues like authentication, tunnel attacks, intelligent system approach, collision detection, congestion avoidance, communication system approach etc.
