Vehicular ad hoc network addressed some issues such as overhead, low throughput of safety related messages, high mobility of the network, less utilization of channel access and hidden terminal problem in dynamic network. Mobility based cluster using hybrid MAC scheme is proposed to reduce the lack of mobility, increase the wireless channel utilization and provide the more stabilization of the VANET. The proposed hybrid clustering mechanism integrates two techniques such as intra-cluster communication using TDMA/CSMA technique and inter-cluster communication using OFDMA technique. Cluster head selection process based on the mobility values to improve the network stabilization.
