Abstract: Vehicular environments impose stringent requirements on the communication channels due to their inherent feature of being geographically constrained, unpredictable vehicular density, varying channel capacity and highly dynamic in nature. Enhancement in the existing vehicular communication technologies is important not only for efficient utilisation of the available bandwidth but also for event-driven safety message dissemination in vehicular ad hoc network (VANET). From safety point of view these enhancements demand high reliability; time bound delivery and inevitable channel access. In this paper we compare and evaluate the performance of mobility aware clustering based single-hop and multi-hop broadcast network in the IEEE 802.11p standard for different node densities and varying data transfer rates. Simulation results using NS-2 are presented to evaluate various quality of service (QoS) parameters such as, throughput, packet delivery ratio and end to end delay. Significant observations have been made which would envisage further research in this field.
