摘要
IoV(Internet of Vehicles)is a promising paradigm to the future of automobiles,which will undoubtedly boost the automobile market as well as accelerate innovation in Internet services and applications.The concept of SD-IoV(Software Defined IoV)is presented,which is capable of improving resource utilization,service quality,and network optimization in the harsh vehicular network environments.First,A generalized SD-IoV architecture as an intuitive big picture is presented.Then,the major functions realized by SD-IoV are elabrated on to illustrate how the current challenges are resolved.As the key enablers of SD-IoV,three possible implementation methods of the wireless control path are described and compared.Finally,the challenges and existing solutions of SD-IoV are disuessed and open issues are pointed out so as to shed light on future research.
