A structured framework that defines how Internet of Things components, protocols, and systems interact to create functional connected device ecosystems.

IoT Architecture

IoT architecture provides the foundational blueprint for how Internet of Things systems are designed, implemented, and managed. This layered approach ensures reliable communication between diverse connected devices while maintaining security and scalability.

Core Layers

1. Perception Layer (Physical Layer)

Sensors and actuators that interact with the physical environment
Data collection and initial processing
Integration with embedded systems
Physical device identification and addressing

2. Network Layer (Transport Layer)

Handles data transmission between devices and platforms
Implements network protocols like MQTT, CoAP, and HTTP
Manages network security and encryption
Ensures reliable communication paths

3. Processing Layer (Middleware)

Data processing and analytics
Device management and authentication
cloud computing integration
Service management and orchestration

4. Application Layer

User interfaces and applications
Business logic implementation
Data visualization and reporting
Integration with enterprise systems
