R-PBFT: Efficient DAG-based consensus Algorithm for Internet of Vehicles
Proceedings of 2025 2nd International Conference on Machine Learning and Intelligent Computing, PMLR 278:587-594, 2025.
Abstract
With the increase in the number of vehicles in residential households, the traffic flow on roads has shown a significant growth trend, which places higher demands on the capacity of vehicular networks. It is worth noting that the traditional PBFT algorithm experiences a significant decline in consensus efficiency as the number of nodes increases, which may pose a key constraint on the information exchange efficiency in vehicular networks. Based on this, this study proposes an R-PBFT consensus algorithm based on DAG blockchain. This algorithm optimizes the consensus mechanism and significantly improves the information transmission rate between roadside units and vehicles. Experimental results show that, compared to traditional consensus algorithms, the proposed solution effectively improves consensus efficiency while reducing communication costs.
