- Abstract
Vehicle-to-vehicle (V2V) video content sharing is promising for connected and autonomous vehicles. However, various security, trust, and privacy risks, coupled with conflicts of interest among different operators, hinder the large-scale promotion of such an application. To address these issues, a consortium blockchain-based framework for cross-operator V2V video content distribution is presented, breaking operators' barriers and achieving a fair value transfer. First, a two-tier consortium blockchain architecture is designed for cross-operator transaction data management. Ledger maintenance and consensus verification are performed within subchains, while user information storage and smart contract execution are conducted between the mainchain and subchains. A multi-constrained vehicle-group selection algorithm is then designed, which minimizes service fees under vehicle reputation, connection duration, and transmission rate constraints. Lastly, an incentive mechanism is developed to promote the rapid upload of transaction data for cross-operator contract invocation. Extensive security analysis and simulation results demonstrate the proposed scheme's feasibility, superiority, and effectiveness.
