Abstract
Aiming at the problems for existing data transmission mechanisms in Internet of vehicles, such as real-time performance, high efficiency of computing tasks, vehicle data privacy, etc., this paper proposes an efficient and secure data transmission mechanism for Internet of vehicles considering privacy protection in fog computing environment. Firstly, this paper proposes a system model and main message attack model for Internet of vehicles in fog computing environment, and designs a data transmission system based on privacy protection to improve data transmission efficiency in Internet of vehicles and protect the privacy information of vehicle users. Then, the task allocation and data aggregation mechanism of privacy protection is proposed in the crowd-sensing model based on the assistance of fog nodes, and the location prediction method based on social infection theory is used to predict the vehicle location for better allocating network resources. Finally, for the selfishness of end users in Internet of vehicles, selfish node incentive mechanism based on Robin Steiner bargaining game model is proposed to encourage selfish nodes to perform data transmission and reduce time delay. Operational network environment simulation software is used to carry out experiments. The experimental results show that when malicious nodes and selfish nodes exist in the Internet of Vehicles, the proposed method has stronger competitiveness in resisting attacks and improving the efficiency of message transmission compared with other methods, which can achieve efficient and secure data transmission.
Highlights
As an important part of social infrastructure, the safety and efficiency of urban transportation networks have a direct impact on urban development and people’s daily lives
With the rapid development of wireless communication technologies, sensing technologies, mobile computing and automation control technologies, The concept of Internet of Vehicles (IoV) came into being and became an indispensable component in the realization of Intelligent Transportation System (ITS) and autonomous driving [1], [2], which is highly valued by the government, academia and industry
While ensuring efficient and reliable wireless data transmission in IoV, more and more attention has been paid to the communication security and privacy issues of IoV [9], [10]
Summary
As an important part of social infrastructure, the safety and efficiency of urban transportation networks have a direct impact on urban development and people’s daily lives. Between cars and cars, cars and people, cars and roads, cars and clouds (platforms), enabling data transmission and information intercommunication between cars and all systems It supports a variety of applications in IoV based on the transmission of car driving information, road state information, traffic warning information, and mobile services [3]. Li: Efficient and Secure Data Transmission Mechanism for IoV Considering Privacy Protection data and high-speed mobile Internet services are increasing sharply on the road. While ensuring efficient and reliable wireless data transmission in IoV, more and more attention has been paid to the communication security and privacy issues of IoV [9], [10]. The research on information security mechanism for IoV becomes the focus of current scholars’ research, which has high theoretical research value
