Abstract:
In today's world, traffic safety is a major problem. Traffic accidents result in more than half a million casualties each year and are associated with serious injuries and extensive material losses. Therefore, special attention is given to those technologies that can reduce the number and severity of road events. Inter-vehicle communication (IVC) and vehicle to road communication (VRC) are considered to have extensive potential for the development of efficient safety systems installed in vehicles, so in order to work these systems more efficiently, suitable innovative system to be implemented.
This paper surveys the current state-of-the-art in wireless communication technology within vehicles, as well as between vehicles. Different concepts associated with radio frequency bands and wave propagation simulations as they apply to inter-vehicle communication are analyzed. The Medium Access Control (MAC) layer protocols used in inter-vehicle communication are addressed, as are routing protocols. Security issues associated with inter-vehicle communication are reviewed. The intra-vehicle uses of wireless communication, and vehicle-to-roadside communication, are also researched. Lastly, a real-life implementation of vehicle-to-infrastructure and vehicle-to-vehicle technology, and CALM defines five communication scenarios, are analyzed
