Perishable Digital Goods Trading Mechanism for Blockchain- Based Vehicular Network

Abstract

Recently, Internet of Vehicles (IoV) equipped with autopilot technology show much concern in their quality of service (QoS), especially in how to ensure the quality of crowdsourcing data for QoS. It is an open issue to encourage high-quality data to be sold as digital goods. Although existing works manage to design incentive mechanisms in data trading for IoV, they fail to address the trust problem. The blockchain technology has been widely studied to establish trust among participants, however, little is currently known about the perishability in the data market, which leads to the failure in explaining the price difference of digital goods. In this paper, we propose a perishability-oriented pricing mechanism to support perishable digital goods trading among IoVs. We also introduce consortium blockchain that provides distributed hyper ledger to address the trust issue in the market. By employing Stackelberg game theory, we obtain the optimal response of selfish users and providers. And finally, we propose a distributed algorithm to simulate our mechanism. Our experiment results demonstrate the efficiency of our distributed algorithm and prove the correctness and consistency of our mechanism.
