Software Defined Internet of Vehicles: Architecture, Challenges and Solutions

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.
