Abstract: vehicular a d -hoc networks include mixed traffic which needs different quality of services. Vanet applications are supported by ieee 802.11p protocol which works on the csma/ca technique. The protocol categorizes the access cate- gories into four priority levels ensuring successful transmission of higher priority packets. However, the increasing number of vehicles with its dynamic topology, probable number of collisions increases, and creating congestion at the control channel. In this paper, a cluster based channel access scheme (cbca) is proposed. Here, the communication to the control channel is done by means of the central node of the non-overlapping clusters of the zone.
