Cover Story: 5G technology will enable the development of a plethora of new services in vehicular scenarios. In this context, it is necessary that the infrastructure guarantee the availability of network resources to different types of applications and users. Following this demand, network slicing in 5G advocates mechanisms to assure quality of service (QoS) to specific data flows and subscribers. In this work, we aim at getting real the slicing concept in the vehicular domain. Hence, we present a slicing framework in an experimental vehicular test-bench based on a mobile edge computing (MEC)-based architecture. It permits traffic differentiation to ensure flow isolation, resource assignment, and network scalability for Internet of Vehicles (IoV). The presented results demonstrate the validity of the solution in terms of short and predictable slice-creation time, QoS assurance, and service scalability. View this paper.
