Several medium access control protocols have been proposed in the recent past in vehicles for accessing radio channels and for distributing timely safety messages for inter-vehicle communication in Vehicular Ad hoc NETworks (VANETs). As contention period for channel access is high in Medium Access Control (MAC), MAC is unable to distribute timely safety messages. To reduce the contention, Region based Clustering Mechanism (RCM), which caters to the reduction of contention by limiting the number of vehicles for each cluster, is applied with MAC protocols. RCM also resolves the competition among vehicles to access radio channels for inter-vehicle communication.
