Applications of IoT
Sudhir Kumar · 2021
The chapter discusses two use cases of smart environments, namely, smart healthcare and smart city. In particular, human activity recognition using wearable sensors and channel state information in a smart healthcare system is presented. The channel state information provides a device-free solution and hence, better than wearable sensors and image/video-based. The image and video-based approach breach the privacy of the user and require a large transmit bandwidth. The chapter also presents smart parking, smart farming, and smart air pollution monitoring for smart city applications. In a smart environment, heterogeneous things send data to the gateway, fog node, or cloud using wireless protocols. Encryption of data can also be carried out in a secured smart environment.
