Book Description
Much has been made of the speed and constancy of modern politics. Whether watching cable news, retweeting political posts, or receiving news alerts on our phones, political communication now happens continuously and in real time. Traditional research methods often do not capture this dynamic environment. Early studies that guided the study of political communication took place at a time when transistors and FM radio, television, and widely distributed films technologically changed the way people gained information and developed knowledge of the world around them. Now, the environment has transformed again through digital innovations. This book provides one of the first systematic assessment of real-time methods used to study the new digital media environment. It features twelve chapters—authored by leading researchers in the field—using continuous or real time response methods to study political communication in various forms. Moreover, the authors explain how viewer attitudes can be measured over time, message effects can be pin-pointed down to the second of impact, behaviors can be tracked and analyzed unobtrusively, and respondents can naturally respond on their smartphone, tablet, or even console gaming system. Leading practitioners in the field working for CNN, Microsoft, and Twitter show how the approach is being innovatively used in the field. Political Communication in Real Time is a welcome addition to the growing field of interest in "big data" and continuous response research. This volume will appeal to scholars and practitioners in political science and communication studies wishing to gain new insights into the strengths and limitations of this approach. Political communication is a continuous process, so theories, applications, and cognitive models of such communication require continuous measures and methods.

Book Description
This book focuses on core functionalities for wireless real-time multi-hop networking with TDMA (time-division multiple access) and their integration into a flexible, versatile, fully operational, self-contained communication system. The use of wireless real-time communication technologies for the flexible networking of sensors, actuators, and controllers is a crucial building block for future production and control systems. WirelessHART and ISA 100.11a, two technologies that have been developed predominantly for industrial use, are currently available. However, a closer analysis of these approaches reveals certain deficits. Current research on wireless real-time communication systems shows potential to remove these limitations, resulting in flexible, versatile, and robust solutions that can be implemented on today’s low-cost and resource-constrained hardware platforms. Unlike other books on wireless communication, this book presents protocols located on MAC layer and above, and build on the physical (PHY) layer of standard wireless communication technologies.

Book Description
This dissertation proposes and investigates an isochronous wireless network for industrial control applications with guaranteed latencies and jitter. Based on a requirements analysis of real industrial applications and the characterisation of the wireless channel, the solution approach is developed. It consists of a TDMA-based medium access control, a dynamic resource allocation and the provision of a global time base for the wired and the wireless network. Due to the global time base, the solution approach allows a seamless and synchronous integration into existing wired Real-time Ethernet systems.

Book Description
Understand and deploy RTC protocols for any kind of communications system Since the emergence of Voice over IP (VoIP) communications in the late 1990s, a set of real time communication (RTC) protocols has evolved that together now support an immense range of technologies and systems architectures. Whether it's 5G networks (and beyond) or Internet of Things architectures, RTC protocols are indispensable to modern telecommunications. An understanding of these protocols and their design and deployment is critical for engineers, academics, and industry professionals in virtually every connected field. Hands-On Real Time Communications offers a thorough yet accessible introduction to this subject, incorporating both the theory and practical applications of RTC protocols. It offers detailed instructions for deploying RTC protocols on various types of network stacks, as well as the use of a huge range of speech, audio, and video codecs. Practice-oriented and designed for students as well as established professionals, it's a must-own for anyone looking to deploy and maintain essential communications architectures. Readers will also find: A matching hands-on section for each theoretical aspect, incorporating license-free protocol analyzers and emulation tools Detailed discussion of topics including signaling, media packetization, real hardware-based network interfaces, and many more End-of-chapter questions and lab exercises to facilitate learning Hands-On Real Time Communications is ideal for advanced undergraduate or graduate students in RTC communication and networking classes, as well as for engineers, technologists, and architects looking to learn and understand the principles of RTC networking.
