Jamming and interference vulnerability of IEEE 802.11p

The IEEE 802.11p standard will in the next years be introduced for vehicle-to-vehicle and vehicle-to-infrastructure (V2X) communication. Some of the services in this standard are dedicated to active road safety applications and can therefore be sensitive to radio interference. Since the system is based on Automatic Repeat Request (ARQ) and Carrier Sense Multiple Access (CSMA), interference problems will, for a constant data rate, appear as packet delays and there is a risk that the packet delay may violate critical delay requirements defined for future safety related applications. In this work we have analyzed interference signal approximations for system performance predictions and the impact on the IEEE 802.11p system in terms of bit and packet error probability and packet delays.
