Preface

The Internet of Things (IoT) refers to a network of physical devices that communicate over the Internet using sensors, software, and other technologies. It has numerous applications in fields ranging from industry (e.g., Industry 4.0) to health care (e.g., telemonitoring, mobile health).

When talking about IoT, it is important to focus on two fundamental aspects: the communication mechanism and the connected devices. The IoT is a multidisciplinary field that integrates both hardware and software.

The expansion in the use of IoT technology in society has not been as widespread as it has been in the field of research. Therefore, although the technology is currently at a high level of maturity, there is still a lot of room for expansion and application in society. For this reason, it is essential that the research studies carried out serve as a transfer to society and allow for the implementation of the IoT in a real environment. Even though the IoT is already being used in everyday life in the form of smart applications, research in this area focuses on more risky solutions.

This book presents several recent studies on the IoT that have great potential to be extrapolated to the real world in the future. We hope that the information contained herein will inspire future advances in the area.
