Institute of Electrical and Electronics Engineers Vehicular communications are already a reality, but they still need to evolve in order to support higher throughput and, above all, ultra-low latency to accommodate new use cases such as the fully autonomous car. In addition, cybersecurity must be guaranteed, since the risk of losing control of vehicles in the face of an attack is undoubtedly a matter of national security. This article presents the technological enablers so that all these requirements can be reached: under the umbrella of a dedicated network slice, this article proposes the use of Content-Centric Networking instead of conventional TCP/IP routing, and permissioned blockchains that allow controlling dynamically the reliability of the source and the integrity and validity of the information exchanged.
True, the scientific community still has a lot to investigate on how to get 5G to have a satisfactory journey in the development of standards. However, it is now that we must begin to glimpse the future of mobile technology, it is time to imagine what 6G will be. This paper offers a realistic view of what this technology might be. In this case, the experience of one of the most important groups in Europe dedicated to the mobile communication systems design, the iTEAM research institute, is combined with the one of the world's leading manufacturers of femtocells, Casa Systems. From the belief that the deployment of 5G will come from homes, this paper analyzes the new use cases of the 6G, as well as the three technological pillars of this future technology.
Much has been written about the virtualization of mobile networks but very little about the practical aspects of this important paradigm shift. In this article, we address the practical aspects of creating an Infrastructure‐as‐a‐Service (IaaS). We first discuss some basic concepts and then focus on most promising technologies that allow the creation of such an infrastructure. Technologies such as OpenStack and Docker are discussed, and a practical implementation with libvirt deployed using Terraform solution is presented. Finally, we discuss specific aspects of Network Function Virtualization (NFV) and how a 5G network can really make use of an IaaS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
