From wearables that understand spoken commands to AR glasses that translate foreign text in real time, the demand for low‑latency, privacy‑preserving, and always‑on AI is exploding. ...

Introduction Edge computing has shifted the paradigm from centralized cloud processing to a more distributed model where data is processed close to its source—smartphones, IoT sensors, autonomous vehicles, and industrial controllers. This shift brings two powerful capabilities to the table: Reduced bandwidth consumption because raw data never leaves the device. Lower privacy risk, as sensitive information stays on‑device. Federated Learning (FL) leverages these advantages by training a global model through collaborative updates from many edge devices, each keeping its data locally. While FL has already demonstrated success in keyboard prediction, health monitoring, and recommendation systems, a new frontier is emerging: real‑time federated learning for latency‑critical applications such as autonomous driving, robotics, and industrial control. ...
