Abstract
The term Internet of Things (IoT) indicates a network of devices connected to collect, exchange, and act on data, enabling intelligent automation and decision-making across multiple applications, including smart homes, healthcare, transportation, agriculture, and many others. At the foundation of the IoT hierarchy are endpoint devices, which integrate multiple sensors and are built around a Microcontroller Unit (MCU). Since they are typically battery-powered, it is essential to limit the power consumption to extend the battery lifetime. In fact, the MCU is very often based on a low-power Central Processing Unit (CPU). However, this implies that the role of the MCU is limited to controlling and lightweight processing, and a lot of raw data are sent throughout the IoT hierarchy.
As communication with higher-level nodes demands significant power, reducing the amount of transmitted data is crucial
