An overview of V2X communications
Abstract
Internet of vehicles,which integrates cutting-edge technologies and devices in the fields of vehicles,roadside infrastructure,communications,positioning,etc.,has been considered as a promising technology to solve the road safety problems.With the advanced information and communication technologies,V2X can greatly improve driving safety,enhance traffic efficiency and comprehensively provide various information services.Thus,it brings unprecedented historical opportunities and challenges to the automobile industry.The state-of-art research on V2X communications was overviewed.Firstly,the background and the characteristics and application scenarios of V2X communication were briefly introduced.Secondly,the development course of V2X communication were outlined.Then,the technical standard of V2X was presented,with emphasis on LTE-V2X and the 5G V2X.Finally,some open problems such as high reliability and low latency,vehicle safety and privacy protection and driving safety of 5G V2X were discussed and concluded.
