A vehicle's on-road time since the last pit stop has to be taken into account while forming clusters using Vehicular Ad-hoc NETworks (VANET). This is important so as to keep the vehicles at optimum driving conditions and to provide rest to the driver at regular intervals. To the best of the user's knowledge, no clustering scheme has considered this important practical issue while designing a routing protocol for VANET. In this paper, the authors present a dynamic and stable cluster-based MAC protocol with a more realistic selection metric that includes the vehicle's on-road time and position messages like relative speed, direction and connectivity among neighboring vehicles while giving priority to vehicles joining a cluster.
