Abstract

Internet of Vehicles is a specific application of Internet of Things technology in intelligent transportation systems, and has attracted attention of relevant research institutions, automobile manufacturers and communication technology suppliers all over the world. The US government has spent hundreds of millions of dollars on DSRC development, which is a technology that can help achieve V2V and V2I communications, and enable vehicles to communicate with intelligent traffic lights to mitigate traffic congestion and accidents or bad weather on the road. Automakers such as GM and Toyota have well deployed Wi-Fi-based DSRC technology. But with the continuous development of 5G and D2D communications, cellular technology tends to be a strong candidate for V2X communications..Although 5G communication technology does not yet have a unified standard, its related concepts and trends have been recognized by industry area. Automobile manufacturers represented by Ford and BMW expect to achieve a leap in automotive networking through 5G. In the face of the 5G era, the dispute between DSRC and LTE standards has become a hot topic in the field of car networking. DSRC, a dedicated short-range communication developed and tested by automotive technology suppliers is under threat, and the next generation of 5G technology might be the final answer. Based on this point, this paper firstly introduces the development history of the Internet of Vehicles communication standard, and analyzes the advantages and disadvantages of DSRC and cellular network communication technology. Then, the three core elements of the Internet of Vehicles (Node Performance, local Network, and Internet of Things) are discussed for the development trend of vehicle networking communication technology in the context of 5G. Finally, this chapter explains the impact of the development of 5G communication technology on the future development of vehicle networking, and proposes the possible development directions of future vehicle networking technologies.

Highlights

The Cyber-Physical Systems(CPS) is a multi-dimensional, integrated system that integrates information, the physical world, and control processes to provide a variety of information services and real-time monitoring of large engineering systems
With the intensive development of 5G, it is foreseen that cities in the future will have a fully connected system in which a large number of smart items and software components are coordinated to achieve different business objectives [13]
The end-to-end delay, channel access delay and network throughput performance of vehicle ad hoc network (VANET) applications will be significantly reduced when the density and network traffic of VANET based on DSRC technology is large [39], while DSRC has a short coverage distance and the disadvantage of high infrastructure costs, and C-V2X is a powerful complement to DSRC technology

Summary

Introduction

The Cyber-Physical Systems(CPS) is a multi-dimensional, integrated system that integrates information, the physical world, and control processes to provide a variety of information services and real-time monitoring of large engineering systems. From an application point of view, CPS covers real-time monitoring and smart home and other aspects closely related to life, and has become increasingly widespread in the field of industrial control and large-scale systems such as intelligent management and monitoring. Wireless technology will make cities smarter and more convenient, and smarter vehicles and networked roadside infrastructure will allow vehicles to communicate with each other and their surroundings [11]. Since 2016, the pace of 5G testing has been accelerated [8], and 5G brings a few Gbps of bandwidth to a single user and provides a few milliseconds of mission-critical delay and securely connects a large number of devices worldwide, increasing the capabilities of a terminal the wireless ecosystem is planning to start the technology upgrade cycle [7]. The importance of wireless communications in transportation is unprecedented [10]
