Special Issue Information

Dear Colleagues,

With the maturity and forthcoming commercialization of the fifth-generation (5G) communication networks, an exponential increase in mobile data demand can be supported, and the varying needs of vertical industries, such as creative, retail, transport, and health, as part of a much broader worldwide revolution in the digital economy. Meanwhile, the total installed base of Internet of Things (IoT) connected devices, such as computers and tablets, is projected to increase to 75.44 billion devices worldwide by 2025, a five-fold increase in a decade. This transition will present a formidable challenge for future mobile communication technology as wireless networks are hitting their physical capacity limits. There is also growing concern about the associated significant increase in energy consumption required to maintain such networks. 

Therefore, it is imperative to develop radical new solutions to support this ever-increasing number of connected devices in smart, energy-efficient ways. To address this, the future 5G and beyond (6G) wireless networks will be a transformative factor for both society and the economy by delivering unprecedented, seamless, massive connectivity to millions of users and interconnected devices. To meet the coming challenges, the sixth generation (6G) mobile network is expected to define the high technical standard of this new spectrum, including energy-efficient transmission techniques.

The objective of this Special Issue is to define the framework of the 6th generation of communication networks, its services and breakthrough technologies. We are soliciting original contributions that have not been published and are not currently under consideration by any other journals. Particular emphasis is placed on radical new concepts and ideas. The topics of interest include, but are not limited to the following:

  • Novel AI-based architectures, frameworks, and testbeds for 6G,
  • New energy harvesting technologies,
  • New antenna array design for massive MIMO,
  • Intelligent spectrum management in 5G/6G using AI-assisted blockchains,
  • Breakthrough technologies and concepts,
  • New network architectures concepts and technologies to harness new spectrum,
  • Techniques to improve energy efficiency in a radio network,
  • Reconfigurable antennas and devices for the next generation,
  • Innovative AI and 6G-enabled user applications,
  • AI applications for the physical layer of wireless communications

As the technical specifications of the 5th Generation (5G) wireless communication standard are being wrapped up, there are growing efforts amongst researchers, industrialists, and standardisation bodies on the enabling technologies of a 6G standard or the so-called Beyond 5G (B5G) one. Although the 5G standard has presented several benefits, there are still some limitations within it. Such limitations have motivated the setting up of study groups to determine suitable technologies that should operate in the year 2030 and beyond, i.e., after 5G. Consequently, this Special Issue of Future Internet concerning what possibilities lie ahead for a 6G wireless network includes four high-quality research papers (three of which are review papers with over 412 referred sources and one regular research). This editorial piece summarises the major contributions of the articles and the Special Issue, outlining future directions for new research. Full article

The digital transformation is exciting the uptake of Internet-of-Things technologies, and raises the questions surrounding our knowledge of the positions of many of these things. A review of indoor localization technologies summarized in this paper shows that with conventional RF-based techniques, a significant challenge exists in terms of achieving good accuracy with a low power consumption at the device side. We present hybrid RF-acoustic approaches as an interesting alternative: the slow propagation speed of sound allows for accurate distance measurements, while RF can easily provide synchronization, data, and power to the devices. We explain how the combination of adequate signaling realizing a late wake-up of the devices with backscattering could position energy-neutral devices. Experiments in a real-life testbed confirmed the potential 10 cm-accuracy based on RF-harvested energy. Nonetheless, these also expose open challenges to be resolved in order to achieve accurate 3D positioning. Full article

As the deployment of 5G mobile radio networks gains momentum across the globe, the wireless research community is already planning the successor of 5G. In this paper, we highlight the shortcomings of 5G in meeting the needs of more data-intensive, low-latency, and ultra-high-reliability applications. We then discuss the salient characteristics of the 6G network following a hierarchical approach including the social, economic, and technological aspects. We also discuss some of the key technologies expected to support the move towards 6G. Finally, we quantify and summarize the research work related to beyond 5G and 6G networks through an extensive search of publications and research groups and present a possible timeline for 6G activities.

The race for the 6th generation of wireless networks (6G) has begun. Researchers around the world have started to explore the best solutions for the challenges that the previous generations have experienced. To provide the readers with a clear map of the current developments, several review papers shared their vision and critically evaluated the state of the art. However, most of the work is based on general observations and the big picture vision, and lack the practical implementation challenges of the Internet of Things (IoT) use cases. This paper takes a novel approach in the review, as we present a sample of IoT use cases that are representative of a wide variety of its implementations. The chosen use cases are from the most research-active sectors that can benefit from 6G and its enabling technologies. These sectors are healthcare, smart grid, transport, and Industry 4.0. Additionally, we identified some of the practical challenges and the lessons learned in the implementation of these use cases. The review highlights the cases’ main requirements and how they overlap with the key drivers for the future generation of wireless networks. Full article

Intelligence Edge Computing (IEC) is the key enabler of emerging 5G technologies networks and beyond. IEC is considered to be a promising backbone of future services and wireless communication systems in 5G integration. In addition, IEC enables various use cases and applications, including autonomous vehicles, augmented and virtual reality, big data analytic, and other customer-oriented services. Moreover, it is one of the 5G technologies that most enhanced market drivers in different fields such as customer service, healthcare, education methods, IoT in agriculture and energy sustainability. However, 5G technological improvements face many challenges such as traffic volume, privacy, security, digitization capabilities, and required latency. Therefore, 6G is considered to be promising technology for the future. To this end, compared to other surveys, this paper provides a comprehensive survey and an inclusive overview of Intelligence Edge Computing (IEC) technologies in 6G focusing on main up-to-date characteristics, challenges, potential use cases and market drivers. Furthermore, we summarize research efforts on IEC in 5G from 2014 to 2021, in which the integration of IEC and 5G technologies are highlighted. Finally, open research challenges and new future directions in IEC with 6G networks will be discussed. Full article
