The deployment of 5G mobile networks has begun in earnest. The 5G network is built on a service-based architecture (SBA) which enables programmability of the control plane of 5G Core (5GC) and ...supports network slicing (NS) in both core and access networks. NS enables the creation of multiple, isolated network slices tailored for specific services with diverse KPI objectives 1. SBA of 5GC facilitates core network user plane functions (UPF) being deployed near the network edge, which has triggered intense interest in edge activities such as Multi-access Edge Computing (MEC), whereas the traditional Self-Organizing Network (SON) functions are being enhanced continuously in 5G RAN. Meanwhile, the development of open and smart RAN led by an industry alliance, O-RAN, has received great attention. In this short paper we would like to sort out if and how all of the above would fit together in a consistent and efficient manner regarding their architecture aspects and functionalities.
The IoT paradigm holds the promise to revolutionize the way we live and work by means of a wealth of new services, based on seamless interactions between a large amount of heterogeneous devices. ...After decades of conceptual inception of the IoT, in recent years a large variety of communication technologies has gradually emerged, reflecting a large diversity of application domains and of communication requirements. Such heterogeneity and fragmentation of the connectivity landscape is currently hampering the full realization of the IoT vision, by posing several complex integration challenges. In this context, the advent of 5G cellular systems, with the availability of a connectivity technology, which is at once truly ubiquitous, reliable, scalable, and cost-efficient, is considered as a potentially key driver for the yet-to emerge global IoT. In the present paper, we analyze in detail the potential of 5G technologies for the IoT, by considering both the technological and standardization aspects. We review the present-day IoT connectivity landscape, as well as the main 5G enablers for the IoT. Last but not least, we illustrate the massive business shifts that a tight link between IoT and 5G may cause in the operator and vendors ecosystem.
Over the last few years, the evolution of network and user handsets' technologies, have challenged the telecom industry and the Internet ecosystem. Especially, the unprecedented progress of ...multimedia streaming services like YouTube, Vimeo and DailyMotion resulted in an impressive demand growth and a significant need of Quality of Service (QoS) (e.g., high data rate, low latency/jitter, etc.). Mainly, numerous difficulties are to be considered while delivering a specific service, such as a strict QoS, human-centric features, massive number of devices, heterogeneous devices and networks, and uncontrollable environments. Thenceforth, the concept of Quality of Experience (QoE) is gaining visibility, and tremendous research efforts have been spent on improving and/or delivering reliable and added-value services, at a high user experience. In this paper, we present the importance of QoE in wireless and mobile networks (4G, 5G, and beyond), by providing standard definitions and the most important measurement methods developed. Moreover, we exhibit notable enhancements and controlling approaches proposed by researchers to meet the user expectation in terms of service experience.
The Internet of Things (IoT) represents the current technology revolution that is intended to transform the current environment into a more pervasive and ubiquitous world. In this emerging ecosystem, ...the application of standard security technologies has to cope with the inherent nature of constrained physical devices, which are seamlessly integrated into the Internet infrastructure. This work proposes a set of lightweight authentication and authorization mechanisms in order to support smart objects during their life cycle. Furthermore, such mechanisms are framed within a proposed security framework, which is compliant with the Architectural Reference Model, recently presented by the EU FP7 IoT-A project. The resulting architecture is intended to provide a holistic security approach to be leveraged in the design of novel and lightweight security protocols for IoT constrained environments.
The data economy has arisen in most developed countries. Instruments and tools to extract knowledge and value from large collections of data are now available and enable new industries, business ...models, and jobs. However, the current data market is asymmetric and prevents companies from competing fairly. On the one hand, only very specialized digital organizations can manage complex data technologies such as Artificial Intelligence and obtain great benefits from third-party data at a very reduced cost. On the other hand, datasets are produced by regular companies as valueless sub-products that assume great costs. These companies have no mechanisms to negotiate a fair distribution of the benefits derived from their industrial data, which are often transferred for free. Therefore, new digital data-driven marketplaces must be enabled to facilitate fair data trading among all industrial agents. In this paper, we propose a blockchain-enabled solution to monetize industrial data. Industries can upload their data to an Inter-Planetary File System (IPFS) using a web interface, where the data are randomized through a privacy-preserving algorithm. In parallel, a blockchain network creates a Non-Fungible Token (NFT) to represent the dataset. So, only the NFT owner can obtain the required seed to derandomize and extract all data from the IPFS. Data trading is then represented by NFT trading and is based on fungible tokens, so it is easier to adapt prices to the real economy. Auctions and purchases are also managed through a common web interface. Experimental validation based on a pilot deployment is conducted. The results show a significant improvement in the data transactions and quality of experience of industrial agents.

In this special issue, we cover some recent results in the following four emerging areas: 5G cellular systems, big data systems, bio/nano/molecular networks, and smart grids. In the past several ...years, there are various technologies emerging, which are either directly or indirectly related to communication. Some of them are over the evolution of traditional communication systems, while others are over new systems such as smart grids, molecular networks, and big data systems.
Abstract-Rapid expansion of 5G affects a number of sectors, including vehicular communications relying on cooperative intelligent transportation systems (C-ITS). More specifically, in the context of ...the Internet of Vehicles (IoV), a particular emphasis is placed on modern cellular V2X (C-V2X) technologies aiming to further improve road safety. This work originates from the detailed scope of the ongoing 5G-DRIVE research project promoting cooperation between the EU and China, with the aim of demonstrating IoV services that rely on vehicle-to-infrastructure (V2I) communications. With the C-V2X approach serving as a point of departure, we analyze and describe a specific green light-optimized speed advisory (GLOSA) use case, for which we provide a detailed descriptive framework, a proposed architectural framework for trials, as well as specific KPIs for the joint assessment of trials between the EU and China. We also discuss the context for performance test procedures to be conducted as part of the intended trials. GLOSA provides end-users with short-term information on upcoming traffic light status to optimize traffic flows, help prevent speed limit violations, improve fuel efficiency, and reduce pollution.

Nowadays, many researchers are interested in the concept of Internet of Things (IoT). IoT is evolving our knowledge and conception of the world. IoT aims to offer a common communication paradigm for ...all objects via the Internet and its protocols. For that reasons, it is being applied in all areas of life, such as environmental monitoring, healthcare, military, cities management, and industry. One of the major challenges of the IoT is to integrate IPv6, and its related protocols, into the constrained capabilities offered by Wireless Sensor Networks, building automation, and home appliances. One of the design considerations, for the success of the IoT, is to integrate what exists from IPv6, before creating novel protocols, in order to promote and ensure the interoperability, homogeneity, openness, security, flexibility, and heritage of all existing hardware, tools, and applications of IPv6. This work presents how to integrate the management protocols in IPv6 into the emerging IoT networks based on protocols such as 6LoWPAN. An overview of the different management protocols for IPv6 is presented. Network Management Protocol (SNMP), and the considerations for IoT management from works such as Lightweight Network Management Protocol (LNMP), and the Constrained networks and devices Management (COMAN) Group from the IETF are discussed. COMAN is presenting solutions such as simplified MIB, new SNMP consideration, and CoAP-based management.
