Q & A

What are the main learning objectives of this lesson?

By the end of this lesson, learners will be able to explain the IoT architecture and frameworks, describe IoT interoperability as design considerations, and discuss industry-aligned use cases.

What are the four layers of IoT device architecture?

The four layers are: 1) IoT Devices (base layer with sensors), 2) IoT Gateway or Aggregation Layer, 3) Processing Engine or Event Processing Layer, and 4) Application Layer or API Management Layer.

What role does the communication layer play in IoT architecture?

The communication layer, or gateway layer, utilizes REST protocols and application-level protocols, generating a large amount of data and acting as a message broker between devices.

How does the event processing and analytics layer contribute to IoT?

This layer drives data transformation and analytics, storing data in databases, and providing insights through dashboards.

What is the significance of the IoT reference architecture?

The IoT reference architecture provides a comprehensive framework, incorporating various components, rule engines, interfaces, and security systems necessary for efficient IoT deployment.

What are some common IoT frameworks mentioned in the script?

The most common IoT framework mentioned is ISO 30141, which offers a standardized vocabulary, reusable designs, and best practices for application development.

What challenges does IoT interoperability face?

Interoperability challenges stem from diverse systems, varying data formats, and the need for common specifications, along with the existence of low-power devices on lossy networks.

What are the key design considerations when choosing an IoT solution?

Factors to consider include wireless capability, functionality, interoperability, secure storage, device categorization, bandwidth, and power management.

How does the decentralized architecture differ from centralized architecture in IoT?

Centralized architecture is managed from one hub providing back-end services, while decentralized architecture allows for autonomous communication among devices without a central hub.

What are the components necessary for smart farming in IoT?
