“…We consider a vehicular communication scenario as depicted in Fig. 1 where a vehicle communicates to the base station using the relay cooperation from transceiver-mounted traffic lights as in [35]. One round of information transmission from a vehicle to the base station is completed in two phases.…”

Vehicular communications allow vehicles to connect with other vehicles and network infrastructures in order to facilitate the transfer of real-time information and dependable transportation. This paper proposes a system that connects vehicles to the network (base station) in two phases using transceiversequipped roadside infrastructures, such as signboards, traffic lights, and street lights, as intermediary relay nodes. In the first phase, the information transfer occurs from vehicles to infrastructure using a radio-frequency (RF) link. The second phase includes establishing communication from the infrastructure to the base station using hybrid free-space optics (FSO)/RF link. In modeling the FSO link, we consider factors like atmospheric attenuation, pointing errors, and atmospheric turbulence-induced fading, which can affect FSO performance. For this set-up, we derive the accurate expressions for the outage probability, system throughput, average symbol error rate, and average end-toend delay. Numerical results corroborate the dependency of the time allocation factor α for the vehicle-to-infrastructure link on the vehicle transmit power. Furthermore, the results elucidate the impact of the length of the transmitted packet and FSO link distance on average end-to-end delay performance. The increase in distance between infrastructure and base station can be compensated by reducing the length of packets to achieve desirable delay performance.

“…Thus, GPS sensors' vulnerability to spoofing attacks poses a severe threat that might be causing vehicles to be out of control or even hijacked and endanger human life [6]. Therefore, GPS spoofing attacks and jamming interference needs to be controlled and detected in real-time to reach secured vehicular communications allowing vehicles to securely talk to each other and interact with the infrastructure (e.g., roadside terminals, base stations) [7].…”

Vehicle-to-Everything (V2X) is an emergent technology for enhancing traffic efficiency, road safety and autonomous driving. Vehicles interconnected with their prevalent wireless environment are prone to various security threats that might affect traffic and life safety immensely. Jamming attacks, a legacy and dated problem, still persists much to the havoc of V2X communications. The following paper proposes a framework for jammer detection adapted to V2X communications scenario. A Generalized Dynamic Bayesian network is used to learn the V2X signal environment in a statistical manner. Subsequently, a Modified Markov Jump Particle filter (M-MJPF) is used for signal predictions where the innovations in the observed signal versus the predicted signal enable our framework to detect the jammer. Simulation results highlight the efficacy and accuracy of our approach in V2X jammer detection.
