This book provides comprehensive coverage on the concepts, frameworks, and underpinning technologies in most aspects of the Internet of Things (IoT), and presents them as the foundation on which more advanced topics, such as 5G and mMTC/M2M, Edge/cloud computing and the modalities of Tactile IoT, Industrial IoT (IIoT)/Industry 4.0, Satellite IoT, and Digital Twins (DT), could be built upon. A key feature of the book is the chapter that focuses on security and privacy for individuals and IoT/ Industry 4.0 are discussed. This book is a good reference guide for researchers, developers, integrators and stakeholders working on research in or development of IoT, particularly where open-source software are deployed.
