Data and Communication Infrastructure in Smart Grids

The communication infrastructure constitutes the key element in smart grids. There have been great advances to enhance the way data is communicated among the different smart grid applications. The aim of this chapter is to present the data communication part of the smart grid with some pioneering developments in this topic. A succinct review of the state of art projects to improve the communication link is presented. An illustrative simulation using LABVIEW is included with a proposed idea of introducing some newly technologies involved in the current and future generations of wireless communication systems.

IoT-Based Management of Smart Microgrid

The present power grid is going through a substantial and radical transformation process. Unification of existing electrical infrastructure with information and communication network is an unavoidable requirement of smart grid deployment and operation. The key characteristics of smart grid technology are full duplex communication, advanced metering infrastructure, integration of renewable and alternative energy resources, distribution automation and complete monitoring, as well as control of entire power grid. Smart grid communication infrastructure consists of varied and hierarchical communication networks. Application of smart grid can be realized in the various the facets of energy utilization. Internet of things also plays a pivotal role in smart grid infrastructure as it provides a ubiquitous communication network. This chapter describes an implementation of internet of things (IoT)-based wireless energy management system for smart microgrid communication infrastructure.

Agent-Affordance Framework of Networked Collective Actions

This chapter details an agent-affordance framework designed to offer an understanding of social change dynamics in rapidly changing information ecosystems. In doing so, it explicates a taxonomy of agents and affordances critical to the Park Geun-hye impeachment. This framework includes four types of agent and three categories of affordance to account for social change dynamics that have become both more decentralized and increasingly intertwined between human and nonhuman computational agents. As communication infrastructure and social and political processes co-adapt, it is imperative to consider how structural and behavioral affordances affect social change. The framework considers the complex web of motivations, processes, and outcomes that support networked collective actions and enable these actions to succeed or fail.

Import of goods of information and communication infrastructure in the context of customs services

Subject. The article updates the issue of information security associated with the extremely intense import of goods of information and communication infrastructure (ICT) and low volume of production of similar goods in the Russian Federation. Objectives. The aim is to develop principles of formation of customs tariff tools to regulate the import of ICT goods in the Russian Federation. Methods. The study employs the content analysis of existing approaches to defining the customs service concept, and general scientific methods of research. Results. The paper presents a unique approach to the development of tools for customs tariff regulation of imports, formulates an original definition of customs service, highlights the contradiction between the current model of implementation of the escalation principle, established by the World Trade Organization, underpins the need to differentiate the rates of import customs duties for the said group of goods. Conclusions. Due to the current specifics of the use of customs and tariff instruments, not all of them are applicable as measures to regulate the import of ICT goods. Currently, the most effective tools for regulating the import of information and communication technology goods are the unified customs tariff and the commodity nomenclature of foreign economic activity.

LEO Satellites Constellation-to-Ground QKD Links: Greek Quantum Communication Infrastructure Paradigm

Quantum key distribution (QKD) has gained a lot of attention over the past few years, but the implementation of quantum security applications is still challenging to accomplish with the current technology. Towards a global-scale quantum-secured network, satellite communications seem to be a promising candidate to successfully support the quantum communication infrastructure (QCI) by delivering quantum keys to optical ground terminals. In this research, we examined the feasibility of satellite-to-ground QKD under daylight and nighttime conditions using the decoy-state BB84 QKD protocol. We evaluated its performance on a hypothetical constellation with 10 satellites in sun-synchronous Low Earth Orbit (LEO) that are assumed to communicate over a period of one year with three optical ground stations (OGSs) located in Greece. By taking into account the atmospheric effects of turbulence as well as the background solar radiance, we showed that positive normalized secure key rates (SKRs) up to 3.9×10−4 (bps/pulse) can be obtained, which implies that satellite-to-ground QKD can be feasible for various conditions, under realistic assumptions in an existing infrastructure.

An Astrocyte-Flow Mapping on a Mesh-Based Communication Infrastructure to Defective Neurons Phagocytosis

In deploying the Internet of Things (IoT) and Internet of Medical Things (IoMT)-based applications and infrastructures, the researchers faced many sensors and their output’s values, which have transferred between service requesters and servers. Some case studies addressed the different methods and technologies, including machine learning algorithms, deep learning accelerators, Processing-In-Memory (PIM), and neuromorphic computing (NC) approaches to support the data processing complexity and communication between IoMT nodes. With inspiring human brain structure, some researchers tackled the challenges of rising IoT- and IoMT-based applications and neural structures’ simulation. A defective device has destructive effects on the performance and cost of the applications, and their detection is challenging for a communication infrastructure with many devices. We inspired astrocyte cells to map the flow (AFM) of the Internet of Medical Things onto mesh network processing elements (PEs), and detect the defective devices based on a phagocytosis model. This study focuses on an astrocyte’s cholesterol distribution into neurons and presents an algorithm that utilizes its pattern to distribute IoMT’s dataflow and detect the defective devices. We researched Alzheimer’s symptoms to understand astrocyte and phagocytosis functions against the disease and employ the vaccination COVID-19 dataset to define a set of task graphs. The study improves total runtime and energy by approximately 60.85% and 52.38% after implementing AFM, compared with before astrocyte-flow mapping, which helps IoMT’s infrastructure developers to provide healthcare services to the requesters with minimal cost and high accuracy.
