Wireless communications technologies are the platform to develop user-centric systems in a multi-device platform that allows mobility and user-friendly interaction. The development of a multi-device platform requires a common language such as Java. This book discusses two different works related with Bluetooth and GPS-GSM communication, to illustrate the capacity of Java language to develop applications that need wireless communications. Java application on the distributed system is introduced by certain keywords, design pattern, software architecture, design process and architecture for ubiquitous space. Furthermore, Java is often used as an embedded programming system, which is a combination of hardware, software, mechanical and other technical components designed to perform a dedicated function, unlike a general purposes computer. This book describes a new development framework for embedded control systems and engine calibration is presented, which supports the modelling of such systems and provides tools for the design and validation activities. An analytical method to express the resonant frequency in terms of the lumped component values is outlined as well.

Reserving data authenticity in a hostile environment, where the sensor nodes may be compromised, is a critical security issue for wireless sensor networks. In such networks, once a real event is detected, nearby sensors generate data reports which are subsequently forwarded to the data collection point. However, the subverted sensors, which have access to the stored secret keys, can launch attacks to compromise data authenticity. They can act as sources for forged reports and inject an unlimited number of bogus reports that fabricate false events "happening" at arbitrary locations in the field. Such false reports may exhaust network energy and bandwidth resources, trigger false alarms and undesired reactions. The authors explain such attacks and that which can be roughly categorised as isolated attacks by each individual compromised node or colluding attacks by a group of collaborating impostors.

Owing to the rapid developments and growth in the telecommunications industry, the need to develop relevant skills in this field are in high demand. Wireless technology helps to exchange the information between portable devices situated globally. In order to fulfil the demands of this developing field, a unified approach between fundamental concepts and advanced topics is required. The book bridges the gap with a focus on key concepts along with the latest developments including turbo coding, smart antennas, multiple input multiple output (MIMO) system, and software defined radio. It also underpins the design requirements of wireless systems and provides comprehensive coverage of the cellular system and its generations: 3G and 4G (Long Term Evolution). With numerous solved examples, numerical questions, open book exam questions, and illustrations, undergraduates and graduate students will find this to be a readable and highly useful text.

Recent years have witnessed tremendous growth in the population of mobile users demanding high performance, reliability and quality-of-service (QoS). Wireless networks are undergoing rapid developments and dramatic changes in the underlying technologies, in order to cope with the difficulties posed by the scarce wireless resource as well as keep up with the increasing day-to-day demand for cost-effective service of multimedia applications. Predicting and optimising the performance and QoS of wireless networks using analytical modelling, simulation experiments, monitoring and testbed-based measurements are crucial to the proper design, tuning, resource management and capacity planning of such networks. This book is dedicated to review important developments and results, explore recent state-of-the-art research and discuss new strategies for performance modelling, analysis and enhancement of wireless networks. The objective is to make analytical modelling, simulation and measurement tools, and innovative performance evaluation methodology possible and understandable to a wider audience.

Next generation wireless and mobile communication systems are rapidly evolving to satisfy the demands of various network users. Due to the great success and enormous impact of IP networks, high-speed transmission is now possible for both indoor and outdoor wireless systems, internet access and web browsing have become the ruling paradigm for next generation system. It is envisioned that new generation wireless networks and hand-held terminals will support a wide variety of multimedia services such as multimedia web browsing, video and news on demand, mobile office system, stock market information, and so on, to mobile users anywhere, anytime in an uninterrupted and seamless way with low-powered handsets. The characteristics of wireless links, as well as the desire to maintain connectivity while on the move, offer significant challenges to provisioning quality of service and the related performance is of central interest. Since the resources (such as time, frequency and code) in the wireless segments of such networks are very limited, over-dimensioning the network resource is equivalent to poor capital investment, while congestion at busy hours could mean lost calls and lost revenues. It is therefore critical for wireless network designers to utilise these resources efficiently and effectively. In response to the above demand for next generation wireless and mobile communication systems, this book aims at providing a timely and concise reference of the current activities and findings in the relevant technical fields. The primary goal is to address the key technical issues pertaining to the integrated new systems and present novel technical contributions. The book contains 14 invited chapters from prominent researchers working in this area around the world.

This exciting new book, which builds on the author's previous book, Spectrum Wars: The Policy and Technology Debate, discusses the evolution of spectrum use and management caused by the rise of 5G and beyond in all wireless technologies, from terrestrial wireless, including mobile and fixed, to non-terrestrial including satellite and drone technologies. A survey of these new technologies and use cases are included, allowing the reader to understand the technical, operational, and commercial context of these systems. This book addresses how the traditional methods used in evaluating spectrum management have changed, including the use and need of low, medium, and high band spectrum to meet user demands and the use of tools such as spectrum sharing to make available much needed spectrum for 5G and beyond. The book also examines how governments are making additional spectrum available for all uses, including recent spectrum auctions, clearing, and shared networks. Public policy challenges, such as the digital divide and the impact of the pandemic, are explored in relation to their impact on spectrum management. Finally, the evolution to 6G that is already occurring, and the impact that 6G will likely have on spectrum management in the future, is reviewed. Written by an expert in the field, this book provides a thoughtful approach to the overall spectrum management regime from allocating spectrum to having it released into the market for 5G and beyond.
