This research develops privacy-preserving, decentralised AI systems where devices learn collaboratively without sharing raw data. Inspired by natural systems like bee colonies, it enables adaptive, self-organising cooperation among devices. The approach improves performance in heterogeneous environments, such as smart cities, while complying with data protection constraints like GDPR.

This study developed a real-time IoT-based system to optimize fishway performance in fragmented rivers. Using sensors, PIT-tag tracking, and machine-learning models, it links climate triggers with hydraulic controls. Adaptive sluice-gate regulation improved fish passage efficiency by 166% without reducing hydropower output, offering scalable, sustainable river management.
