Special Issue Information

Dear Colleagues,

The Internet of Things (IoT) is enabled by heterogeneous technologies, devices, and platforms, where they work together towards providing sensing, collecting, acting, processing, managing and analysing data. The emergence of the IoT concept has led to the pervasive interconnection of people, services, and devices. However, new systems in the IoT domain that employ smart solutions having embedded intelligence, connectivity and processing capabilities for edge devices rely on real-time processing at the edge of the IoT network—near the end user. Current, traditional cloud computing and IoT solutions are not able to support real-time applications, since they are designed to offer non-real-time services, e.g., stress detection in IoT smart farming applications, while they are offered at a high cost. The computation remains at the cloud, i.e., at the provider data center, while heavy analytics, visualisations, and user-aware services need long times; they are expensive, and they pose privacy issues since personal information is stored and processed in the backbone centralised servers. Next-generation IoT (NG-IoT) systems and solutions require low latency and ultra-fast analytics, given that they bring advanced smart technologies and applications with embedded intelligence, connectivity, and processing capabilities. The implementation of a reliable connectivity between devices, sensors and computing platforms is of fundamental importance towards achieving the goals of NG-IoT applications.

This Special Issue will cover a wide range of research challenges and trends related to NG-IoT architectures, requirements and applications. Researchers are invited to submit novel contributions in, but not limited to, the following topics:

  • NG-IoT reference architectural models;
  • NG-IoT testbeds, paradigms, and applications;
  • Fifth generation (5G) technologies and NG-IoT;
  • Software-defined networking (SDN) developments and applications in NG-IoT;
  • Network function virtualisation (NFV) orchestration in NG-IoT;
  • Artificial intelligence (AI) on the edge;
  • Digital twins and tactile IoT;
  • NG-IoT privacy and security frameworks;
  • Traffic engineering, quality-of-service (QoS), and quality-of-experience (QoE) optimisation in NG-IoT;
  • Blockchain applications for NG-IoT;
  • Energy-efficiency applications in NG-IoT;
  • NG-IoT applications in healthcare and medicine applications;
  • NG-IoT applications in industrial applications;
  • NG-IoT applications for precision agriculture, food safety and quality.

Manuscript Submission Information

Manuscripts should be submitted online at by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Digital is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1000 CHF (Swiss Francs).

The technological leap of smart technologies and the Internet of Things has advanced the conventional model of the electrical power and energy systems into a new digital era, widely known as the Smart Grid. The advent of Smart Grids provides multiple benefits, such as self-monitoring, self-healing and pervasive control. However, it also raises crucial cybersecurity and privacy concerns that can lead to devastating consequences, including cascading effects with other critical infrastructures or even fatal accidents. This paper introduces a novel architecture, which will increase the Smart Grid resiliency, taking full advantage of the Software-Defined Networking (SDN) technology. The proposed architecture called SDN-microSENSE architecture consists of three main tiers: (a) Risk assessment, (b) intrusion detection and correlation and (c) self-healing. The first tier is responsible for evaluating dynamically the risk level of each Smart Grid asset. The second tier undertakes to detect and correlate security events and, finally, the last tier mitigates the potential threats, ensuring in parallel the normal operation of the Smart Grid. It is noteworthy that all tiers of the SDN-microSENSE architecture interact with the SDN controller either for detecting or mitigating intrusions. Full article
