This book discusses the fundamental concepts that are essential to understanding IP multicast communication. The material covers the well‑known IP multicast routing protocols, along with the rationale behind each protocol. The book starts with the basic building blocks of multicast communications and networks, then progresses into the common multicast group management methods used, and finally into the various, well‑known multicast routing protocols used in today’s networks. IP multicast provides significant benefits to network operators by allowing the delivery of information to multiple receivers simultaneously with less network bandwidth consumption than using unicast transmission. Applications that can benefit greatly from multicast communications and multicast‑enabled networks include audio and video conferencing, collaborative computing, online group learning and training, multimedia broadcasting, multi‑participant online gaming, and stock market trading. This book’s goal is to present the main concepts and applications, allowing readers to develop a better understanding of IP multicast communication. IP Multicast Routing Protocols: Concepts and Designs presents material from a practicing engineer’s perspective, linking theory and fundamental concepts to common industry practices and real‑world examples.

Информация – инструмент контроля, тот, кто владеет ею, обретает власть. Мы – люди информационного века. Мы привыкли делать покупки на Amazon, общаться через Facebook, задавать поисковые запросы Google и просто убивать время, пользуясь продукцией Apple. Эти четыре компании-гиганта объединяет одно свойство – все они называют себя защитниками человеческой индивидуальности и многообразия мнений, действующими во имя интересов всех людей. Но так ли все хорошо? Или за «бескорыстными» целями техномонополий стоит тирания голодных до наших данных алгоритмов?

In recent years, the application of Artificial Intelligence (AI) and Internet of Things (IoT) technologies in smart healthcare has been increasing. We are approaching a world where connected smart devices tell people when they need to visit a doctor because these devices will be able to detect health problems and discover symptoms of illness that may need medical care. AI-collaborative IoT technologies can help medical professionals with decision-making. These technologies can also help develop a sustainable and smart healthcare system. Internet of Things (IoT)-enabled technologies and devices have several applications in healthcare. A larger role for IoT in healthcare would be beneficial for both patients and professionals. Medical apps for mobile devices and wearable technology that collect health information from patients are two examples of how healthcare IoT is being put to use. The Internet of Things is used in crisis facilities to follow the whereabouts of patients, clinical gear, and staff. IoT refers to the network of devices, sensors, and objects that are connected to the Internet, allowing them to communicate with each other and collect and transmit data. IoT technology provides capabilities such as identification, communication, services, computing, sensing, and data transfer. These functions enable various applications in healthcare and other fields.

As a typical cyber-physical system (CPS), networked robotic systems refer to a collection of robotic devices or agents that are interconnected through a network, allowing them to communicate, share information, and coordinate their actions. These systems combine robotics with networked communication technologies to enable robots to work together or with other devices, often remotely, to perform tasks and achieve objectives. As one of the core equipments and actuators, robotic technology has attracted much attention and has made great progress. However, a single robotic system is often unable to handle complex tasks due to limitations in sensors, microprocessors, actuators, and the ability to handle complex situations. With the development of distributed control and microprocessing technology, networked robotic systems have greatly expanded their perceptual, computational, and execution capabilities, with high efficiency, low cost, and strong functionality advantages. In this book, we conduct research on the secure coordination problem of networked robotic systems from a control theory perspective, given the limited communication bandwidth and the increasingly prominent network security threats. This book showcases several continuous-time and event-triggered secure control design and analysis methods for networked robotic systems under different types of cyberattacks.
