Recent advances of various wireless communication technologies and the emergence of computationally rich vehicles are pushing Vehicular Ad-hoc NETwork (VANET) research to the forefront in academia and industry. A lot of research results have been published in various areas (such as routing, broadcasting, security, and others) of VANET in the last decade covering both Vehicle-To-Vehicle (V2V) and Vehicle-To-Infrastructure (V2I) scenarios. One specific area of VANET that still faces significant challenges is the design of reliable and robust Media Access Control (MAC) protocols for V2V communications. The authors present a survey of V2V MAC methods (including various VANET standards) that have been proposed for VANETs over the last few years.
