The ever-increasing requirement of massive connectivity, due to the rapid deployment of internet of things (IoT) devices, in the emerging 5th generation (5G) mobile networks commands for even higher utilization of the available spectrum. Non-orthogonal multiple access (NOMA) is a promising solution that can effectively accommodate a higher number o...

Supervisory Control and Data Acquisition (SCADA) systems are the underlying monitoring and control components of critical infrastructures, such as power, telecommunication, transportation, pipelines, chemicals and manufacturing plants. Legacy SCADA systems operated on isolated networks, that made them less exposed to Internet threats. However, the...

Dense small cell deployment in a Cloud Radio Access Network (C-RAN) is an effective approach to satisfy the increasing requirements of the emerging Fifth Generation (5G) mobile networks. Nevertheless, the optimal deployment of small cells is not always possible, due to certain limitations, such as the existence of backbone infrastructure and approp...

The emergence of next-generation internet-of-things (NG-IoT) applications introduces several challenges for the sixth-generation (6G) mobile networks, such as massive connectivity, increased network capacity, and extremely low-latency. To countermeasure the aforementioned challenges, ultra-dense networking has been widely identified as a possible s...

The Internet of Vehicles (IoV) is an emerging paradigm, which is expected to be an integral component of beyond-fifth-generation and sixth-generation mobile networks. However, the processing requirements and strict delay constraints of IoV applications pose a challenge to vehicle processing units. To this end, multi-access edge computing (MEC) can...

The rapid growth of the Internet of Things has shaped the design and deployment of mobile networks to accommodate the need for ubiquitous connectivity and novel applications. The recent advancements in wireless communications and computing technologies allow the connection of a wider range and number of devices and systems, thereby enabling the des...

When fully implemented, sixth generation (6G) wireless systems will constitute intelligent wireless networks that enable not only ubiquitous communication but also high-accuracy localization services. They will be the driving force behind this transformation by introducing a new set of characteristics and service capabilities in which location will...

This paper introduces a novel semi-grant-free non-orthogonal multiple access protocol that ensures reliable massive connectivity of both scheduled and random access devices of diverse data rate (DR) requirements while tripling the network’s capacity. In more detail, the protocol classifies the devices into two categories, namely primary and seconda...

Energy efficiency lies at the very core of policy interventions for energy security, energy poverty and climate change, while it also is promoted by technological innovations and investments. However, it seems that these technologies are not adopted by consumers at least to the extent that the assumption of rational behavior would predict. The EVID...

Ultra-low latency connections for a massive number of devices are one of the main requirements of the next-generation tactile Internet-of-Things (TIoT). Grant-free non-orthogonal multiple access (GF-NOMA) is a novel paradigm that leverages the advantages of grant-free access and non-orthogonal transmissions, to deliver ultra-low latency connectivit...

Dense small cell deployment is an effective way to address the increasing requirements of the emerging Fifth Generation mobile networks. The Cloud Radio Access Network (C-RAN) is an emerging concept that can achieve very dense small cell deployment. In ultra-dense C-RAN architectures with numerous Remote Radio Heads (RRHs), the minimization of the...

The Industrial Control Systems (ICS) are the underlying monitoring and control components of critical infrastruc-tures, which consist of a number of distributed field devices, such as Programmable Logic Controllers (PLCs), Remote Terminal Units (RTUs) and Human Machine Interfaces (HMIs). As modern ICS are connected to the Internet, in the context o...

The exponential proliferation of the Internet of Things (IoT) concept renders it an integral part of the emerging 5th Generation (5G) of mobile networks. In order to address the requirement of massive IoT-type connections, the spectrum has to be better utilized. Non-Orthogonal Multiple Access (NOMA) is a promising technique that can effectively imp...
