Introduction to Edge AI and IoT
With IoT, devices from home appliances to industrial machines are interconnected, collecting vast amounts of data.
By 2025, the number of IoT-connected devices is expected to exceed 30 billion, generating zettabytes of data every year.
However, traditional IoT systems rely heavily on cloud computing for data processing, resulting in latency issues and dependence on network connectivity.
Edge AI is changing this model by enabling IoT devices to process data locally on the device or near the source of data. T
his paradigm shift towards “intelligence at the edge” is poised to be a game-changer for real-time applications, privacy-focused industries, and scenarios where network connectivity is unreliable.
Understanding Edge AI
Edge AI combines AI and edge computing, allowing AI algorithms to operate locally on IoT devices instead of sending data to centralized cloud servers.
With edge processing capabilities, devices can process data immediately, generating insights at the source, improving responsiveness, and reducing bandwidth requirements.
Edge AI typically involves:
- Edge Devices: Devices that collect data (e.g., sensors, cameras, mobile devices).
- Edge Nodes: Gateways or small servers close to the edge device, capable of processing data locally.
- Microcontrollers and Processors: Specialized chips designed for local AI processing, such as Google’s Edge TPU and Nvidia’s Jetson.
This shift allows IoT devices to make autonomous decisions, enabling rapid responses in critical applications such as healthcare, automotive, and industrial automation.
