Abstract:

With the explosive development of the intellectualization and network connection of the global automobile industry,the communication technology as a crucial support of the Internet of vehicles (IoV) is facing the problem of spectrum shortage.In addition to providing security services,the diverse service demands of the IoV make the introduction of the cognitive radio technology an effective solution,which can share heterogeneous spectrum resources integrating the sub-6 GHz and millimeter-wave spectrum resources with primary users.But the performance is limited due to the influence of the complex dynamic environment of the IoV.To address this issue,a novelty method was proposed which aimed to make full use of the potential multi-source dynamic spatiotemporal data,mine and learn the changing rules of the vehicle trajectory and traffic flow,and the rules were used to guide the sensing and sharing of the spectrum resource.The system-level simulation platform was built for simulation analysis,the results showed that the performance of the proposed scheme was effectively improved.

Key words: Internet of vehicles, dynamic spatiotemporal data, heterogeneous spectrum sharing, multi-service quality of service requirement
