A Survey on Fog Computing Applications in Internet of Vehicles

As the technology of network, wireless transmission and big data computing develops rapidly, the society has entered the Information Era. Internet of Vehicles, the important part of the Internet of Things, is the inevitable trend of urban traffic in the future. Fog computing emerges as a new technology of distributed computing, which is suitable for applications in the Internet of Vehicles. Internet of Vehicles based on fog computing can solve the problems of traffic congestion, transportation efficiency and security. In this paper, we review the recent work in this topic and analyze the architecture and scenario of fog computing in the Internet of Vehicles. Three aspects of applications are proposed in this paper: VANET, big data processing and security. At the same time, we discuss the technical details and challenges in these applications. Fog computing has excellent processing power in real-time big data and a high mobility environment, which reduces the latency of data processing, makes the deployment between vehicles and roadside units more reasonable and enhances the security of information interchanged in the Internet of Vehicles. Fog computing devices will become an indispensable part of the future construction of Internet of Vehicles.
