Abstract :
Vehicular ad hoc network (VANET) is one of the recent and promising technologies for revolutionizing the transportation system where vehicles can communicate by sending message with each other via a wireless medium. VANET provide the communication framework for dissemination of safety critical message such as beacons and emergency messages. Congestion in the communication channel results in packet drops, throughput reduction and degradation of channel quality. So, congestion control schemes are necessary to regulate the traffic level at an acceptable level. This paper reviews various existing MAC protocols used for controlling congestion. Based on this, a design approach has been proposed to control congestion.
