Adaptive Resource Reservation to Survive Against Adversarial Resource Selection Jamming Attacks in 5G NR-V2X Distributed Mode 2

New Radio Vehicle-to-Everything (NR-V2X) distributed communication mode utilizes a semi-persistent scheduling (SPS) scheme, in which a reserved radio resource is used for a certain duration. However, attackers can exploit the predictability of SPS’s resource assignment to cause packet dropping, by selecting already reserved resources. In this paper, we first develop a feedback-based attack detection strategy then devise the optimal evasion policy based on a fuzzy inference system that dynamically adapts the resource reservation time. Simulation results show the effectiveness of our scheme in greatly reducing packet dropping-based attacks, and also in improving the packet reception ratio within the network.
