Internet of Things (IoT) architecture involves multiple layers that work together to enable communication and data processing between devices and systems. Understanding these layers helps in designing efficient and scalable IoT solutions.
Core Layers of IoT Architecture
IoT architecture typically consists of three main layers: perception, network, and application. Each layer has specific functions and plays a vital role in the overall system.
Perception Layer
The perception layer includes sensors and devices that collect data from the environment or objects. These devices monitor parameters such as temperature, humidity, or motion.
Network Layer
The network layer transmits data from sensors to processing systems. It uses various communication protocols to ensure reliable data transfer over different distances and environments.
- Wi-Fi
- Bluetooth
- LoRaWAN
- Cellular (3G, 4G, 5G)
Application Layer
The application layer processes data and provides insights or controls. It includes user interfaces, dashboards, and cloud services that enable decision-making and automation.
