The Vehicular Safety Consortium (VSC), the Crash-Avoidance Metrics Partnership (CAMP) consortium and the Vehicle Infrastructure Initiative (VII) along with the giants of the light-duty vehicle manufactures, are working to develop pre-competitive safety technologies and various applications that can be offered in Vehicular Ad-hoc NETworks (VANETs), a special kind mobile ad-hoc networks where wireless equipped element called On-Board Unit (OBU) in vehicles form a network with the Road-Side Unit (RSU) without any additional infrastructure. In this paper, the authors are primarily categorizing various possible applications of vehicular network, along with its features, and implementations in the real world.
