摘要
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 cyber-attacks,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.
