Smart Contract-based Crowdsensing Framework for Internet of Vehicles

Abstract

Crowdsensing of Internet of Vehicles (IoV) can make full of use of the mobility of vehicles to provide data collection services to individuals in deed. In this paper, we elaborate on the framework, operation procedures of both centralized and distributed crowdsensing frameworks in IoV, and analyze the system complexity, secure communication, data storage and other problems facing the current architecture. In order to solve these problems, this paper proposed a crowdsensing framework of IoV based on blockchain and smart contract on the basis of introducing vehicular edge computing; Secondly, a multi-level smart contracts interaction system were built which designed a detailed multi-module smart contract; Finally, a specific scheme for performing sensing tasks is presented on this framework, showing the communication between different entities. The simulation test and performance evaluation certify the availability, security and convenience of the framework.
