An Incentive Mechanism for Nondeterministic Vehicular Crowdsensing with Blockchain

With the increase in the number of on-board sensors, vehicles have shown great potential in mobile crowdsensing. To ensure the capability of the vehicular crowdsensing system, it is necessary to inspire sufficient vehicles to participate. However, due to personal interests and privacy protection, this goal is not easy to achieve. In addition, uncertain mobility of vehicles also brings challenges to the design of incentive mechanism. In this paper, we propose an incentive mechanism for nondeterministic vehicular crowdsensing with blockchain (INVCB), which can effectively incentivize vehicles while protecting user privacy. We first propose a framework for nondeterministic vehicular crowdsensing with blockchain and design a series of smart contracts to automate the crowdsensing process. Then, in order to improve the quality of sensing data, we add reputation attribute to each user, and provide an incentive mechanism that considers reputation. Extensive simulation results show the performance of our proposal is reliable and effective.
