IoT Level-3

A Level-3 IoT system has a single node. Data is stored and analyzed in the cloud and application is cloud-based as shown in Figure 1.8. Level-3 IoT systems are suitable for solutions where the data involved is big and the analysis requirements are computationally intensive.

Working of IoT Level-3

A Level-3 IoT system consists of a single IoT device that performs sensing and/or actuation. Unlike Level-2 systems, where only data storage is performed in the cloud, Level-3 systems utilize the cloud for both data storage and data analysis. The IoT device continuously sends data to the cloud, where powerful computing resources perform computationally intensive analytics.

The application is also cloud-based, enabling users to remotely monitor the system and receive real-time insights. Since cloud resources provide high processing capability, Level-3 systems are suitable for applications involving large volumes of data and complex analytics.

Example: Package Handling Tracking System

Let us consider an example of a Level-3 IoT system for tracking package handling.

The system consists of a single node (for a package) that monitors the vibration levels for a package being shipped. The device in this system uses accelerometer and gyroscope sensors for monitoring vibration levels.

The controller service sends the sensor data to the cloud in real time using a WebSocket service. The data is stored in the cloud and visualized using a cloud-based application.

The analysis components in the cloud can trigger alerts if the vibration levels become greater than a threshold.

The benefit of using a WebSocket service instead of a REST service in this example is that the sensor data can be sent in real time to the cloud. Moreover, cloud-based applications can subscribe to the sensor data feeds for viewing the real-time data.
