A novel blockchain for social internet of vehicles in the Era of 5G and Beyond
Abdellah Kaci, Abderrezak Rachedi · 2022
The Social Internet of Vehicles (SIoV) paradigm is a social network where every vehicle establishes social relationships with others. The IEEE Standards Association develops a number of market relevent standards for for 5G and Beyond. Among these standards, the IEEE P1931.1 standard provides a promising architectural framework for SIoV. In this paper we propose RoofCoin, a blockchain for SIOV based on the IEEE P1931.1 standard. In order to deal with constrains related to Internet of Vehicles, we also provide a novel consensus protocol for RoofCoin, named PoSt(Proof of Stature). In PoSt, the blockchain’s miners are selected according to three features: the mining price, the reliability of the connection link between the vehicle and the miner, and the miner’s reputation. In order to evaluate the miner’s reputation, we introduce a trust model that calculate the miner’s stature in the Vehicular Social Network (VSN). Experimental results have shown that the proposed PoStprotocol is efficient even in low coverage zones, where only two trusted miners are discovered.
