IoT Level-6

A Level-6 IoT system has multiple independent end nodes that perform sensing and/or actuation and send data to the cloud. Data is stored in the cloud and application is cloud-based as shown in Figure 1.11. The analytics component analyzes the data and stores the results in the cloud database. The results are visualized with the cloud-based application. The centralized controller is aware of the status of all the end nodes and sends control commands to the nodes.

Working of IoT Level-6

A Level-6 IoT system consists of multiple independent IoT end nodes that communicate directly with the cloud. Each node performs sensing and/or actuation independently and transmits the collected data to the cloud in real time.

The cloud provides centralized services for:

• Data storage
• Data analytics
• Visualization
• Device management

The analytics component processes the collected data, extracts useful information, and stores the analysis results in the cloud database. The cloud-based application visualizes these results for users.

Unlike Level-5, where a coordinator node acts as a gateway, Level-6 has no coordinator node. Instead, every end node communicates directly with the cloud.

A centralized controller, located in the cloud, continuously monitors the status of all connected IoT devices. Based on the analysis results, it sends control commands back to the respective end nodes whenever required.

Example: Weather Monitoring System

Let us consider an example of a Level-6 IoT system for weather monitoring.

The system consists of multiple nodes placed in different locations for monitoring temperature, humidity and pressure in an area.

The end nodes are equipped with various sensors such as:

• Temperature sensor
• Humidity sensor
• Pressure sensor

The end nodes send the data to the cloud in real time using a WebSocket service.

The data is stored in a cloud database.

The analysis of data is performed in the cloud to aggregate the data and make predictions.

A cloud-based application is used for visualizing the data.
