简介
The Internet of Vehicles (IoV) enables vehicles and Road-Side-Unit to communicate and exchange data, promising to improve transportation safety, efficiency, and convenience. However, to realize the full potential of IoV, secure and fast traffic accident information (TAI) communication among IoV nodes are essential. The Practical Byzantine Fault Tolerance (PBFT)-based blockchain for IoV secures TAI; it is prone to high message overhead and transaction latency, which causes TAI transmission between IoV nodes to be delayed. This paper proposes a new consensus algorithm, named HN-mPBFT (Healthy Node based Modified PBFT), specifically designed for IoV. The HN-mPBFT consensus method reduces message overhead and transaction delay by reducing PBFT consensus phases while achieving consensus among healthy nodes. According to security analysis, HN-mPBFT is secure from Sybil and DDoS …
