The Internet of Things (IoT) has emerged as a new paradigm that connects the physical world with the digital world. It is a network of interconnected devices, sensors, and objects that can communicate with each other, collect and exchange data, and perform various tasks without human intervention. The IoT has the potential to revolutionize various industries, such as healthcare, transportation, manufacturing, and agriculture, by enabling real-time monitoring, automation, and optimization of processes. This book is a collection of research manuscripts that explores the latest developments in smart technologies for sustainable living with reference to the IoT landscape, including its architecture, applications and challenges. The research covers a wide range of topics including character segmentation, recognition and classification, deep learning, smart home, earthquake early-warning system, wireless sensor network, embedded RFID system and many more. It also discusses various IoT platforms, protocols, and standards that are being developed to enable seamless integration and interoperability of IoT devices and services. The research book aims to become a valuable resource for researchers, practitioners, and policymakers interested in smart technologies and sustainable living.
