【Abstract】Recent advances in wireless technology and embedded systems enable vehicles to share relevant traffic-related data to improve the transportation Quality-of-Service (QoS). However, due to the ubiquitousness of cyberattacks, it is challenging to ensure the integrity of the data collected from cars. This paper proposes a novel architecture for road traffic events management in Vehicular Ad hoc NETworks (VANETs) relying on a permissioned blockchain. It also introduces the concept of micro-transactions to minimize communication and storage overhead. Through simulations, a rigorous performance evaluation of the proposed approach was conducted, and the micro-transactions effectiveness was assessed. In addition, a comparison with close works in the literature was performed. The proposed scheme ensures road traffic records integrity and traceability, and simulation results on the considered scenarios showed good performance.
