Abstract:

Smart vehicles, through dedicated sensors, can gather and announce information about road traffic events. This information can be exploited to improve the transportation system. However, with the ubiquity of cyber-attacks, it is challenging to safely store and share event messages collected through Vehicular Ad hoc NETworks. Therefore, in this work, we leverage blockchain technology capability to establish a decentralized, transparent and robust database to build, in turn, a robust and secure traffic event management protocol. We adapt the Proof of Work consensus mechanism to this context while testing network configurations via NS-3. The performance of the blockchain is evaluated and its reliability in the presence of attackers (malicious vehicles) is examined and discussed. The results highlight a trade-off between the events trustworthiness and the blockchain-s reliability and security.
