An Overview: Various Attacks in VANET

In the current era of technological challenges in data transmission, there is a big need to identify the major components and tools which are used in transferring and receiving data for vehicular objects. Vehicular Ad-hoc Network (VANET) has become one of the most popular areas of research in past decades. Vehicles are connected in an adhoc manner in a wireless environment called VANET that is a subpart of MANET. Due to frequent change in topological structure, it is very difficult to make a VANET secure. In this research article, it is being observed that many security challenges are there where research have to step-up forward for making VANET more secure. A critical analysis is discussed broadly with respect to VANET components, security issues and challenges, attacks and its solutions.
