STUDY OF VANET COMMUNICATION ARCHITECTURE AND CHALLENGES FOR SECURITY SOLUTIONS

VANETs are useful for V2V (vehicle-to-vehicle) communications in such a special network. Vehicles can also communicate with roadside infrastructure (V2I). These are two important, logical, and useful features of VANET. V2I enables the mobile node to connect to the Internet and enables global communication on the go. The detailed V2V function allows the exchange of data, for example, accidents and environmental conditions [5]. The idea of utilizing radio communications in vehicles to enhance safety has been around for a long time, even before the appearance of digital communications. In recent years, vehicle safety has been focused on communication between vehicles.
