Location-based trustworthy services recommendation in cooperative-communication-enabled Internet of Vehicles

Abstract With the development of the Internet of Vehicles (IoV), several potential convenient applications, e.g., road safety and security, streaming services, traffic monitoring and driving comfort, have been proposed in recent years. However, the discovery and dissemination of convenient applications requires communication among service providers and service requesters through constrained networks. As an intelligent integrated network architecture, IoV suffers in terms of network data collection, real-time data interaction and sufficient data sharing due to the intrinsic network architecture constraints. In addition, because the implemented network access technologies and communication protocols are not uniform, the facilities involved in the IoV lack a unified communication protocol stack and data interface, which complicates the interconnection and cooperative communication in the whole network. To address these issues, a proprietary cooperative communication architecture and protocol stack are designed for the IoV. On this basis, a location-based trustworthy services recommendation method is developed to satisfy a user's personalized and precise service requirements. Finally, the implementation of the proposed cooperative communication architecture and protocol stack and the location-based trustworthy services recommendation method are discussed, and a performance evaluation conducted via an extensive set of experiments is presented.
