Understand the future of the Internet with this wide-ranging analysis. “Metaverse” is the term for applications that allow users to assume digital avatars to interact with other humans and software functions in a three-dimensional virtual space. These applications and the spaces they create constitute an exciting and challenging new frontier in digital communication. Surmounting the technological and conceptual barriers to creating the Metaverse will require researchers and engineers familiar with its underlying theories and a wide range of technologies and techniques. Metaverse Communication and Computing Networks provides a comprehensive treatment of Metaverse theory and the technologies that can be brought to bear on this new pursuit. It begins by describing the Metaverse’s underlying architecture and infrastructure, physical and digital, before addressing how existing technologies are being adapted to its use. It concludes with an overview of the challenges facing the Metaverse. The result is a thorough introduction to a subject that may define the future of the Internet. Edge-computing technologies are considered to be one of the fundamental infrastructures for the realization of the full-dive Metaverse. Edge computing refers to the deployment of edge servers with cloud computing capabilities at the edge of networks that can be accessed by end devices via wireless connections.

Enables readers to understand applications of attribute-based encryption schemes in cloud computing with the support of blockchain technology. With a focus on blockchain technology, Attribute-based Encryption (ABE) provides insight into the application of attribute-based encryption (ABE) schemes, discussing types of blockchains, fundamentals of blockchain, and how blockchains are constructed. Comprised of 16 chapters, the text provides an overview of the components that go into creating a dual ABE system of encryption proofs within the following: composite bilinear groups, dual pairing vector space framework, matrix pairing framework, framework for matrix pairing, and the application of cryptographic scheme on blockchain. The team of authors discuss the basic construction components of ABE and share the security models, including the selective and semi- adaptive security models, applying these to either prime order or composite order groups. Attribute-based Encryption (ABE) is an essential resource for professionals working in the field of design and cybersecurity who wish to understand how to use blockchain and the ABE scheme to provide fine-grained access control in outsourced data on third-party cloud servers.

In this book, we present the novel state estimation methods for several classes of networked multi-rate systems. The content of this book can be divided into two parts. In the first part, we show the state estimation methods for networked multi-rate systems with various complex network-induced phenomena. The state estimation methods for networked multi-rate systems under the communication protocols are presented in the second part. The systems we investigated include stochastic non-linear systems, time-delay systems, linear repetitive processes, and Artificial Neural Networks (ANNs). The complex networkinduced phenomena considered are time-delays, integral measurements, sensor resolutions, and dynamical bias. The communication protocols included are the Round-Robin protocol, the weighted Try-Once-Discard protocol, the p-persistent carrier sense multiple access protocol, and the dynamic event-triggered protocol. The techniques used are mainly the Lyapunov stability theory, the optimal estimation theory, the lifting technique, and certain convex optimization methods. This book provides valuable reference materials for researchers who wish to explore the state estimation for multi-rate systems. With the rapid development of wireless communication technology and digital technology, networked systems have been widely applied in practical applications such as process monitoring, power grids, industrial control systems, and traffic systems. In networked systems, the signals generated by system components, including the sensors, underlying plant, and controllers, are first sampled and then transmitted through communication networks.

6G is currently under definition, being often addressed from a plain telecommunications perspective as an evolutionary paradigm that represents an extension of 5G. Having as a horizon 2030, 6G initiatives are being deployed across the globe to further ignite the development of 6G services. At its philosophical core, 6G embodies the "human in the loop" principle. The research effort being developed towards 6G requires an interdisciplinary approach that ignites discussion across different key technological sectors, ranging from communications up to services and business cases. The contributions of this book to research in the field concern an evolutionary and interdisciplinary design of 6G as a paradigm that can be addressed by working together four different computational areas: communications; satellites and navigation; sensing; services. The book is, therefore, intended to assist in developing critical thinking to back up novel networking, applications, and services towards 6G.

The book covers the multidimensional perspectives of the Metaverse through the prism of virtual reality, augmented reality, blockchain, Artificial Intelligence, and IoT, ranging from rudimentary to advanced applications. This book provides a thorough explanation of how the technology behind Metaverse and other virtual reality technologies are changing the world. The primary objective is to present the revolutionary innovation of the 21st century―the Metaverse―and exhibit its wide range of applications in different domains. Although blockchain and VR/AR were the first popularly known applications of the Metaverse, several other applications also exist. While some still believe the Metaverse is overhyped, in reality, it is transforming almost every industry―healthcare, 3D, 4D, industry, game industry, business management, Artificial Intelligence (AI), and IoT, just to name a few. This technological breakthrough not only paved the way for virtual reality but also provided useful solutions for other areas of technology. The unique nature of the technology, which is a single, shared, immersive, persistent, 3D virtual space where humans experience life in ways not possible in the physical world, makes it suitable for all real-world applications; it has great potential to transform business, and companies are already in the race for different product offerings.
