Описание:
Focusing on an important and complicated topic in wireless network design, Wireless Quality of Service: Techniques, Standards, and Applications systematically addresses the quality-of-service (QoS) issues found in many types of popular wireless networks.
In each chapter, the book presents numerous QoS challenges encountered in real-world applications and delineates ways to overcome these obstacles. Some of the challenges explored are performance impairments in WLAN hotspots, video streaming applications, and broadband wireless access. The techniques and mechanisms covered to tackle these problems include medium access and call admission control techniques, a parameter tuning algorithm, the QoS-enabling features of IEEE 802.11e, a Markov chain model, a probe-based distributed admission control mechanism, topology-transparent scheduling protocols, and a novel multicast congestion control mechanism.
Addressing advanced topics and future directions, the expert contributors acknowledge the need for more research to solve several open issues. In the meantime, they offer innovative solutions to solve current QoS problems.

Описание: Over the past two decades we have witnessed the increasing popularity of the internet of things. The vision of billions of connected objects, able to interact with their environment, is the key driver directing the development of future communication devices. Today, power consumption as well as the cost and size of radios remain some of the key obstacles towards fulfilling this vision.
Ultra-Low Power FM-UWB Transceivers for IoT presents the latest developments in the field of low power wireless communication. It promotes the FM-UWB modulation scheme as a candidate for short range communication in different IoT scenarios. The FM-UWB has the potential to provide exactly what is missing today. This spread spectrum technique enables significant reduction in transceiver complexity, making it smaller, cheaper and more energy efficient than most alternative options.
The book provides an overview of both circuit-level and architectural techniques used in low power radio design, with a comprehensive study of state-of-the-art examples. It summarizes key theoretical aspects of FM-UWB with a glimpse at potential future research directions. Finally, it gives an insight into a full FM-UWB transceiver design, from system level specifications down to transistor level design, demonstrating the modern power reduction circuit techniques.
Ultra-Low Power FM-UWB Transceivers for IoT is a perfect text and reference for engineers working in RF IC design and wireless communication, as well as academic staff and graduate students engaged in low power communication systems research.
Описание: This book focuses on emerging issues in power-aware portable multimedia communications devices beyond low-power electronic design. It compiles system-level power management approaches, from theoretical and simulation studies to experimental test beds related to low power computing, mobile communication and networking.

Описание: . RFID and Wireless Sensors using Ultra-Wideband Technology explores how RFID-based technologies are becoming the first choice to realize the last (wireless) link in the chain between each element and the Internet due to their low cost and simplicity. . Each day, more and more elements are being connected to the Internet of Things. In this book, ultra-wideband radio technology (in time domain) is exploited to realize this wireless link. Chipless, semi-passive and active RFID systems and wireless sensors and prototypes are proposed in terms of reader (setup and signal processing techniques) and tags (design, integration of sensors and performance). The authors include comprehensive theories, proposals of advanced techniques, and their implementation to help readers develop time-domain ultra-wideband radio technology for a variety of applications. . This book is suitable for post-doctoral candidates, experienced researchers, and engineers developing RFID, tag antenna designs, chipless RFID, and sensor integration.
