Abstract: MAC design in a vehicle network is a challenging task due to high node speed, frequent topology changes, lack of infrastructure, and different QoS requirements. Several medium access control protocols based on Time Division Multiple Access (TDMA) have recently been suggested for VANETs in an effort to guarantee that all cars have sufficient time to send safety messages without collisions and to decrease the end-to-end delay and the loss ratio of packets. The reasons for using the collision-free media access control paradigm in VANETs are identified in this document. We then present a new topology-based classification and provide an overview of the MAC protocols suggested for VANETs based on TDMA. We concentrate on these protocols ‘ features as well as their advantages and constraints. Finally, we provide a qualitative comparison and address some open problems that need to be addressed in future studies to enhance the efficiency of TDMA-based MAC protocols for vehicle-to-vehicle (V2V) and vehicle to infrastructural (V2I) communications.
