Directional analysis of jamming attack for connected vehicular platoons

Nowadays, one of the most promising developments for a safer and more sustainable mobility is the Connected and Autonomous Vehicle (CAV), where the Advanced Driving Systems (ADAS) and connectivity cooperate and take advantage of each other. The Cooperative Adaptive Cruise Control (CACC) might be one of the beneficiaries of such collaboration, being in turn the key enabler of platooning. While this cooperation improves safety and driving efficiency, it also opens the door to increasingly sophisticated cyberattacks. This paper analyses a CACC based platoon model approach in which communication is vulnerable to jamming attack. Jamming attack refers to to an unwanted signal radiated by a malicious device intended to impair the quality of an operating link. Two different platooning variants are compared taking diverse scenarios into account. The presented approach shows how platooning can be susceptible to cyberattacks and some directional measures to mitigate it are proposed.
