LMIRA: Load-Balanced Multi-Indicator Reputation and Authentication Security Blockchain Framework for Cross-Domain Vehicular Data Sharing

This paper presents LMIRA, a blockchain-based framework designed to improve data sharing between vehicles across different network domains in the Internet of Vehicles (IoV, a system where vehicles communicate with each other and infrastructure). The framework addresses three main problems: uneven distribution of computational load on the blockchain, unreliable shared vehicle information, and slow authentication processes that threaten privacy. LMIRA uses edge computing (processing data closer to where it's generated rather than in distant data centers) with a prediction model to anticipate transaction volume, evaluates vehicle data quality using multiple factors, and introduces a new secure authentication method.
