The Internet-of-Things (IoT) revolution has triggered the need of massive connectivity for billions of devices requiring a system capacity which is far beyond the current network designs that can be supported. This emerging requirement has reshaped the society and industry in pursuing efficient communication paradigm. In particular, massive machine-type communications (mMTC) will be a prime driver for enabling the vision of scalable IoT with heterogeneous applications, where the massive access is of paramount importance. This book discusses important massive IoT scenarios and the key technical requirements of the corresponding massive access. We review the state-of-the-art IoT standards and mMTC solutions, and summarize the limitations of the existing schemes from the perspectives of the network architecture, random access procedure, and multiple access techniques. Here, we specify the massive access challenges and reveal that the facilitation of MTC invokes a dramatically different access scheme from current ones mainly designed for human-centric communications. Moreover, we propose several promising massive access solutions to overcome the limitations, where sufficient theoretical model and algorithm design guidance are provided. Besides, detailed simulation and engineering implementation methods are also included.

Digital worlds and cultures-social media, web 2.0, youtube, wearable technologies, health and fitness apps-dominate, if not order, our everyday lives. We are no longer 'just' consumers or readers of digital culture but active producers through facebook, twitter, Instagram, youtube and other emerging technologies. This book is predicated on the assumption that out understanding of our everyday lives should be informed by what is taking place in and through emerging technologies given these (virtual) environments provide a crucial context where traditional, categorical assumptions about the body, identity and leisure may be contested. Far from being 'virtual', the body is constituted within and through emerging technologies in material ways. Recent 'moral panics' over the role of digital cultures in teen suicide, digital drinking games, an endless array of homoerotic images of young bodies being linked with steroid use, disordered eating and body dissatisfaction, facebook games/fundraising campaigns (e.g. for breast cancer), movements devoted to exposing 'everyday sexism' / metoo, twitter abuse (of feminists, of athletes, of racist nature to name but a few), speak to the need for critical engagement with digital cultures. While some of the earlier techno-utopian visions offered the promise of digitality to give rise to participatory, user generator collaborations, within this book we provide critical engagement with digital technologies and what this means for our understandings of leisure cultures. The chapters originally published in a special issue in Leisure Studies.

Until recently, most network design techniques employed a bottom-up approach with lower protocol layer mechanisms affecting the development of higher ones. This approach, however, has not yielded fascinating results in the case of wireless distributed networks. Addressing the emerging aspects of modern network analysis and design, Evolutionary Dynamics of Complex Communications Networks introduces and develops a top-bottom approach where elements of the higher layer can be exploited in modifying the lowest physical topology-closing the network design loop in an evolutionary fashion similar to that observed in natural processes. This book provides a complete overview of contemporary design approaches from the viewpoint of network science and complex/social network analysis. A significant part of the text focuses on the classification and analysis of various network modification mechanisms for wireless decentralized networks that exploit social features from relevant online social networks. Each chapter begins with learning objectives and introductory material and slowly builds to more detailed analysis and advanced concepts. Each chapter also identifies open issues, while by the end of the book, potential research directions are summarized for the more interested researcher or graduate student. The approach outlined in the book will help network designers and administrators increase the value of their infrastructure without requiring any significant additional investment. Topics covered include: basic network graph models and properties, cognitive methods and evolutionary computing, complex and social network analysis metrics and features, and analysis and development of the distinctive structure and features of complex networks. Considering all aspects of modern network analysis and design, the text covers the necessary material and background to make it a suitable source of reference for graduate students, postdoctoral researchers, and scientists

Presenting encryption algorithms with diverse characteristics, Image Encryption: A Communication Perspective examines image encryption algorithms for the purpose of secure wireless communication. It considers two directions for image encryption: permutation-based approaches and substitution-based approaches. Covering the spectrum of image encryption principles and techniques, the book compares image encryption with permutation- and diffusion-based approaches. It explores number theory-based encryption algorithms such as the Data Encryption Standard, the Advanced Encryption Standard, and the RC6 algorithms. It not only details the strength of various encryption algorithms, but also describes their ability to work within the limitations of wireless communication systems. Since some ciphers were not designed for image encryption, the book explains how to modify these ciphers to work for image encryption. It also provides instruction on how to search for other approaches suitable for this task. To make this work comprehensive, the authors explore communication concepts concentrating on the orthogonal frequency division multiplexing (OFDM) system and present a simplified model for the OFDM communication system with its different implementations. Complete with simulation experiments and MATLAB (R) codes for most of the simulation experiments, this book will help you gain the understanding required to select the encryption method that best fulfills your application requirements.

Go Beyond Basic Distributed Circuit Analysis An Introduction to Microwave Measurements has been written in a way that is different from many textbooks. As an instructor teaching a master's-level course on microwave measurements, the authorrecognized that few of today's graduate electrical engineering students are knowledgeable about microwave measurements beyond basic distributed circuit analysis. Written in a "how-it-works" spirit-strongly borrowing from instrument catalogs and application notes-this text covers a wide range of topics, clarifies many terms used widely on the subject, and equips the reader with the ability to grasp more advanced material.It starts with a brief overview of the basic theory and the building blocks required for understanding and using microwave measurement techniques. Oriented around the most commonly used instruments in microwave measurements-the network analyzer, the spectrum analyzer, and synthesized microwave source-it introduces the latest instruments and techniques and provides a brief description of traditional measurement techniques (slotted waveguide etc.). It offers an introduction to the mathematical basis behind microwave measurements as well as an overview of some of the practical components that are frequently used in microwave instruments. Observing that students generally grasp the subject better when actual numbers are given, rather than symbolic relations, the author includes examples involving numerical values that are scattered throughout the book. He also provides a detailed description of the vector network analyzer and the spectrum analyzer (explaining its principle of operation and calibration), which form the backbone of modern microwave measurements. In addition, he briefly addresses advanced topics such as pulsed measurements and non-linear network analysis. Comprised of ten chapters, this text: Discusses noise measurement and synthesized signal generation Provides an overview of RF wafer-probing and modern microwave oscilloscopes-relatively advanced topics Contains detailed derivations and exercises An Introduction to Microwave Measurements provides proficiency in subjects related to radio frequency (RF) and microwave systems, and is an ideal resource for senior undergraduate and first-year master's-level students as well as professionals in the wireless industry who deal with such systems but are not specialists in the area.
