In order to propose a hybrid terrestrial-satellite architecture for the 5G infrastructure in Brazil, it is sought to discover and understand the resources and tools used in the simulation or emulation of these network architectures for performance analysis purposes when evaluating various technological interoperability scenarios. Based on the main projects of the European Commission H2020 and standardization organizations of the 5G network, such as 3GPP, ETSI, ITU, among others, this article investigates how the standardization and implementation of 5G terrestrial network management and virtualization technologies are being applied. It highlights the use cases and the tools used in their investigations.

<p>This paper scrutinizes the influence of deployment scenarios on the energy performance of fifth-generation (5G) network at various backhaul wireless frequency bands. An innovative network architecture, the hybrid centric-distributed, is employed and its energy efficiency (EE) model is analyzed. The obtained results confirm that the EE of the 5G network increases with an increasing number of small cells and degrades with an increasing frequency of wireless backhaul and radius of small cells regardless of the network architectures. Moreover, the hybrid centric-distributed architecture augments the EE when compared with the distributed architecture.</p>

Insight Into

During this last decade, the blockchain (BC) paradigm is being required in several use cases and scenarios in particular for security, privacy, and trust provisioning. Accordingly, the research community and developers developed several emulation tools and frameworks for BC-based systems performance analysis. Making an adequate decision regarding the choice of the most suitable tool that can be used to develop and validate the performances of a specific BC-based system or application still requires more investigation. In this context, this chapter describes and highlights the most features and characteristics of the BC platforms and tools within the Hyperledger framework. The goal is to illustrate the advantages and the limitations of several BC tools and development environments within Hyperledger. In addition, this chapter provides an insight into BC 3.0 as the new generation of BC that meets the requirements of the smart application.

The Future

The fifth generation (5G) of wireless communication systems is considered the key technology to enable a wide range of application scenarios and the effective spreading of the smart city concept. Vertical business use cases, specifically designed for the future 5G city, will have a strong economical and social impact. For this reason, ongoing 5G field trials have to test newly deployed technologies as well as the capability of 5G to create a new digital economy. This paper describes the 5G field trial environment that was launched in Italy at the end of 2017. The aim is to evaluate the capability of the 5G network of supporting innovative services with reference to suitably designed key performance indicators and to evaluate the opportunities offered by these services. Indeed, vertical business use cases, specifically designed for the future 5G city, with a strong economic and social impact, are under implementation and will be evaluated. In particular, the paper provides a detailed description of the deployment of an actual complete integrated 5G network. It shows how 5G is effective enabling technology for a wide range of vertical business and use cases. Indeed, its flexibility allows to satisfy completely different performance requirements of real services. Some preliminary results, obtained during the first phase, are presented for a smart mobility scenario.

The Internet Of Things

The Fifth Generation of Mobile Communications (5G) will lead to the growth of use cases demanding higher capacity and a enhanced data rate, a lower latency, and a more flexible and scalable network able to offer better user Quality of Experience (QoE). The Internet of Things (IoT) is one of these use cases. It has been spreading in the recent past few years, and it covers a wider range of possible application scenarios, such as smart city, smart factory, and smart agriculture, among many others. However, the limitations of the terrestrial network hinder the deployment of IoT devices and services. Besides, the existence of a plethora of different solutions (short vs. long range, commercialized vs. standardized, etc.), each of them based on different communication protocols and, in some cases, on different access infrastructures, makes the integration among them and with the upcoming 5G infrastructure more difficult. This paper discusses the huge set of IoT solutions available or still under standardization that will need to be integrated in the 5G framework. UAVs and satellites will be proposed as possible solutions to ease this integration, overcoming the limitations of the terrestrial infrastructure, such as the limited covered areas and the densification of the number of IoT devices per square kilometer.
