Abstract:

This paper proposes a cooperative downloading incentive scheme based on a two-layer game in the Internet of Vehicles,in which the reverse auction mechanism is used to select cooperatively downloading vehicles,and the evolutionary game solves the problem of vehicles participating in data forwarding.At the same time,the use of sequential aggregated signature technology ensures the security of the data transmission process.In addition,the Bitcoin-based timing commitment mechanism realizes electronic currency incentives and ensures the fairness of transaction payments.Finally,theoretical analysis shows that the scheme achieves data integrity,identity authentication,and non-repudiation,can effectively promote vehicle cooperation and achieve fairness in transactions.Simulation results prove the effectiveness of the scheme in terms of communication cost and storage cost.

Key words: internet of vehicles, cooperative download, reverse auction, evolutionary game, sequential aggregated signature, fair payment, incentive
