The event took place at the Centre for Advanced Academic Studies (CAAS) of the University of Zagreb , which offers a stunning view of Dubrovnik's Old Town's famous City Walls and Lovrijenac Fortress. The event was organised in collaboration with the EU-funded   SmartEdge   project and brought together more than 40 participants from all over Europe. The programme of the summer school included invited talks, technical tutorials and hands-on sessions, as well as the technical programme of the workshop “ Edge AI meets Swarm Intelligence ” with paper presentations and poster sessions showcasing the latest research results by PhD students. Key highlights of the Summer School include:   Keynotes   by Aaron Ding (TU Delft) on sustainable and trustworthy edge AI for future computing, Stefan Nastic (TU Vienna) on computing paradigms for next-generation computing landscapes, Spyros Lalis (University of Thessaly )  on elevating drones to first-class citizens in the cloud-edge-IoT continuum.  Tutorials on doctoral education at KTH, insights on operating distributed computing continuum systems through active inference, exploring privacy-preserving computation techniques for edge AI, in-network programming and practical guidelines for startups with examples. Hands-on sessions included two open-source solutions: 1) AIoTwin orchestration middleware enabling edge orchestration of hierarchical Federated Learning workflows and 2) ColonyOS , an event-driven meta-operating system spanning edge and cloud environments. Joint technical workshop with the project SmartEdge on “ Edge AI meets Swarm Intelligence ”. The event successfully promoted collaboration and networking between academics, PhD students and industry professionals through interactive sessions, giving researchers and participants the opportunity to share insights on edge AI , swarm intelligence and edge orchestration .

The project leader and head of the Internet of Things Laboratory at FER, Prof. Ivana Podnar Žarko , delivered a talk titled "Artificial Intelligence of Things (AIoT): Bringing Intelligence into the Physical World" at the Digital Futures cross-disciplinary research center in Stockholm, Sweden, on August 29th 2024. The talk introduced the concept of AIoT as a continuous processing cycle consisting of four steps: sensing, learning, decision-making, and acting. This cycle was illustrated with concrete real-world use cases. The challenges of AIoT were also reviewed, highlighting its operation in a dynamic and heterogeneous environment with limited resources dedicated to real-time data processing, online learning, inference, and decision-making under time constraints. Additionally, it was noted that data streams from IoT devices are often incomplete, prone to errors, and unlabelled. The talk further emphasized that AIoT systems must adhere to strict privacy and security requirements to protect sensitive user data, ensure device integrity, and maintain the safety of the physical environment.

At the IEEE International Conference on Edge Computing and Communications - IEEE EDGE 2024 held in Shenzhen, China from 7 to 13 July 2024, the paper " QEdgeProxy: QoS-Aware Load Balancing for IoT Services in the Computing Continuum " by Ivan Čilić , Valentin Jukanović, Ivana Podnar Žarko , Pantelis Frangoudis , and  Schahram Dustdar was presented. The paper was accepted after an international review and presented remotely by Ivan Čilić. The work results from a collaboration between IoTLab at FER and DSG at TU Wien on orchestration and routing in Computing Continuum (CC). The paper introduces  QEdgeProxy , an adaptive and QoS-aware load-balancing framework specifically designed for routing client requests to appropriate IoT service instances in the CC. QEdgeProxy integrates naturally within Kubernetes, adapts to changes in dynamic environments, and manages to seamlessly deliver data to IoT service instances while consistently meeting QoS requirements and effectively distributing load across them.
