A survey of lower layer technologies for Vehicle-to-Vehicle communication

Vehicle-to-Vehicle (V2V) communication is an evolving research field that has potential to augment safety on our roads. Safety focused V2V communication also offers convenience and commercial applications in order to enhance driving comfort and pleasure. V2V communication demonstrates unique characteristics and consequently reliable network access has become crucial to exploit a wide spectrum of applications. Development of complex networking protocols, ingenious medium access control (MAC) techniques and robust communication technology are the main challenges to reliable and pragmatic V2V communication. This paper provides survey of lower layer technologies proposed for V2V communication and concludes with analytical summary drawn from the survey.
