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.
