Abstract—Vehicular Ad Hoc Networks (VANETs) are a
special type of Mobile Ad Hoc Networks (MANETs). Recent
advances in various wireless communication technologies and
the emergence of computationally rich vehicles are pushing
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. Many algorithms of V2V MAC methods
(including various VANET standards) have been proposed for
VANETs over the last, few years that also focused on the
benefits and limitations of the proposed MAC techniques as
well as their ease of implementation in practice and future
deployment. In this paper, we have made the performance
analysis of Carrier sense multiple access (CSMA), Multiple
Access with Collision Avoidance (MACA) and Multiple
Access with Collision Avoidance for Wireless (MACAW) for
VANET environment.
Index Terms—CSMA, MACA, MACAW, media access
control, VANETs.
