New paper accepted and presented at...

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.

AIoTwin was at Open Doors Day 2023 at...

On Saturday, November 25, 2023, the Open Doors Day of the Faculty of Electrical Engineering and Computing (FER) took place and attracted numerous visitors. This event offered the public, especially high-school students, the opportunity to explore the study programmes available at FER and learn about the ongoing research projects. Numerous departments and laboratories showcased their work, including the Internet of Things Laboratory.

Ivan Kralj, Katarina Mandarić, Ivan Čilić, Dora Kreković, and Mislav Has presented the recently completed IoT-field project, which encompasses a comprehensive IoT solution from sensors through an interoperable platform to a user application for monitoring crops and meteorological conditions in the field. Attention was also drawn to the urban garden set up in the FER courtyard and the quantity of the harvest.

Visitors were particularly interested in the involvement of students in projects, and it was emphasized that, over the course of more than 3.5 years of the IoT-field project, students were actively engaged, resulting in a significant number of group projects, as well as undergraduate and graduate theses.

In addition to IoT-field, we presented the AIoTwin project, highlighting our collaboration with technical universities in Vienna and Berlin, as well as the RISE research center in Sweden. A new concept, the Artificial Intelligence of Things (AIoT), was introduced and explained. AIoT brings artificial intelligence into our physical environment and removes the boundaries between the physical and digital worlds, opening up new possibilities for device intelligence and autonomy in the physical environment.

Furthermore, assistants shared their experiences and impressions from their undergraduate, graduate, and doctoral studies with the visitors, mostly high school seniors and eighth-grade elementary school students.

This Open Doors Day of FER has, traditionally, proven to be extremely informative, contributing to the promotion of studies and science.

Lodovico presented a series of three lectures with a special focus on Graph Neural Networks (GNNs) and decentralized systems and shed light on these cutting-edge technologies.

On November 8th, he gave a public talk entitled "Causal Temporal GNNs as Decentralized Memory Networks," , co-organized by the IEEE Croatian Section,  which was open to the general public to provide a broad audience with a glimpse into the evolving landscape of GNNs and decentralized systems.

In contrast, the following two presentations were tailored for members of the AIoTwin project, offering a more specific exploration of these cutting-edge technologies.

  • Decentralised Data Mining using Gossip Protocols: This lecture introduced the broad family of Gossip Protocols and presented a detailed analysis of a few key use cases and specific techniques.
  • Graph Representation Learning with Graph Neural Networks: This lecture introduced the broad topic of Graph Representation Learning (GRL), with a particular focus on Graph Neural Network (GNN) techniques.

During the lectures Lodovico explored the foundational principles of GNNs, their diverse applications, and the inherent challenges associated with decentralized systems. Attendees gained a better understanding of the dynamic nature of graphs, the implications of temporal changes on algorithms, and the intricacies of decentralized inference in GNNs.

The 1st AIoTwin Summer School was a 3-day event held at the historic St. John’s Fortress in Šibenik, Croatia, September 4-7, 2023. The event brought together participants from academia, both renowned experienced researchers and PhD students, to exchange ideas and learn about the latest advances at the intersection of AI and IoT. The summer school was organized by the AIoTwin consortium, a Horizon Europe project that aims to strengthen research and innovation excellence in AIoT in Croatia and other EU Member States. 

Key highlights from the Summer School include: 

  • Keynotes by Petar Šolić on alternative sensing, Danh Le Phuoc on using knowledge graphs to build perceptual IoT systems, Thiemo Voigt on the road to in body and battery-free IoT, and Alexander Artikis on complex event recognition. 
  • Tutorials on LPWA protocols, the IMUNES network emulator for performance evaluation of edge deployments, orchestration aspects in distributed computing continuum systems, decentralized graph mining, successful PhD journey, and proposal writing and evaluation of collaborative Horizon Europe projects. 
  • Hands-on sessions on federated learning for IoT edge devices using a small cluster of Jetson Nano and Xavier devices (specially transported from Berlin to Šibenik!) to jointly train models without sharing raw data, and on the framework for creating high-level Service Level Objectives (SLOs) to enforce them in cloud and edge environments. 
  • PhD poster and pitch session where PhD students presented their research on a variety of innovative topics. 

The event provided a valuable opportunity for participants to network with other experts in the field and to be inspired to pursue careers in AIoTwin research and development. 

The AIoTwin consortium is committed to organizing future summer schools and other events to promote research and innovation in AIoT.
