Enhancing Trust Model of Information Vehicular Ad-Hoc Networks Through Blockchain Consensus Algorithm

Vehicular Ad-hoc Networks (VANETs) presents smart transport that is capable of processing data and can self-organize for each vehicle. However, there have been security issues such as communication breakdowns between vehicles and information trust. Therefore, the trust model becomes an essential element in overcoming this problem. Various trust models have been suggested in the literature, including the model that utilizing consensus algorithm in the blockchain. This paper proposes an extension of the blockchain consensus algorithm based on Proof of Event (PoE) and Proof of Location (PoL) strategy, which call Proof of Event and Location (PoEL). Finally, it presents an initial experimental result on the effectiveness of our blockchain consensus algorithm extension. The simulation results show that the proposes blockchain consensus algorithm extension shows an increase in making blocks by 2% to 17% when the simulation is done with a different number of nodes.
