DDoS attack on WAVE-enabled VANET through synchronization

Subir Biswas, Jelena Misic, Vojislav Misic
2012 2012 IEEE Global Communications Conference (GLOBECOM)  
A VANET that uses IEEE 802.11p EDCA mechanism is susceptible to a synchronization-based DDoS attack due to periodicity of transmissions and small contention window sizes.  ...  To make things worse, neither the sender nor receivers of periodic broadcasts will be aware of the attack since broadcast communications in VANET do not have acknowledgements.  ...  We organize the rest of the paper as follows. DSRC and EDCA mechanism of IEEE 802.11p MAC are explored in Section II. Our attack model is presented in Section III.  ...
