Safety impact of DoS attacks on V2X-based collision warning

The dataset represents Straight Crossing Path (SCP) intersection scenarios, where a Host Vehicle (HV) and a Remote Vehicle (RV) approach a right-angled intersection at different velocities and cross each other's paths simultaneously. By manipulating the starting positions, the driving scenarios were defined in such a way that the two vehicles collide in all cases.

Scenarios were implemented with the following speed levels:

We quantified the safety risk (Safety Risk Index - SRI) related to the specific V2X scenarios based on network performance metrics (End-to-End latency – E2E; Packet Delivery Ratio – PDR).

In our dataset, we differentiated the strength of the attack based on the primary wireless communication parameters:

·         the attacker's data transmission rate (AR),

·         the attack packet length (APL).

Based on the six driving scenarios (S1-S6) and the attack parameters (attack packet length, attack rate), 780 scenarios were simulated for a total of 15,600 unique test points (20 static spatial measurement point / scenario).
