The IEEE Task Group has approved recently the


802.11p amendment to enable efficient short range communications


for vehicular networks by introducing multiple enhancements


at the physical and MAC layer. It defines a control


frequency channel for control and most critical data packets


and one or several service frequency channels for less critical


packets. In this paper, we propose an analytical model for


the 802.11p operations in the control frequency. It captures all


suggested enhancements important for exchanging data packets


generated by road safety applications. We showed through


diverse simulations scenarios that our proposed model is able


to reproduce expected results. We consider this work as an important


step toward understanding the performance of 802.11pbased


vehicular communications and the model can be employed


in the simulations of safety applications in large scenarios.
