IoT4us project is funded by the Croatian Science Foundation under the grant number 1986.
At the 16th KES International Conference, KES-AMSTA 2022, held in hybrid form from 20 to 22 June 2022 in Greece on the island of Rhodes, the paper "Negotiation-Based Multi-agent System for Ambient Conditions Control in Accordance with Multiple User Preferences" by Katarina Mandarić, Pavle Skočir, Gordan Ježić and Ignac Lovrek was presented. The paper was accepted after an international review.
The work is the result of continued research into the Cognitive Internet of Things Smart Home with a focus on intelligent personalized service provision to users. The paper describes a Multi-Agent System where each user is represented by its own agent in setting the device settings according to their preferences, with an emphasis on the problem of harmonizing the different preferences of multiple users who use the device/service at the same time.
On Thursday, June 30, 2022, we organized a public presentation of the IoT4us project, which was attended by numerous guests from the industry, the academic community, and students.
After the introductory words of the project manager, prof. Ivana Podnar Žarko, PhD, members of the research team presented their work and results. Postdoc Petar Krivić, PhD and research assistant Ivan Čilić presented a solution for the application of computing resources at the edge of the network (edge computing) in the field of the Internet of Things. Then research assistant Katarina Mandarić presented the use of intelligent software agents in the Internet of Things Smart Space to set ambient conditions according to the preferences of all present users in the space. Assistant Karlo Slovenec gave a presentation on security, i.e. securing administrative interfaces of IoT devices. The event continued with the presentation of the assistant, Denis Salopek, PhD on fast and energy-efficient packet filtering, and this part of the event was closed by teaching assistant Federico Matteo Benčić with a presentation on adapting networks of distributed ledgers for environments with limited resources.
After the work lunch, the event continued at the Department of Telecommunications, where guests were welcomed by members of the IoTLab laboratory and students who demonstrated selected practical solutions developed within the IoTLab through bachelor and final theses, as well as projects in the Internet of Things course. We thank everyone for their participation!

Research assistant Katarina Mandarić, MSc, member of the project research team, gave a lecture at the conference "Ladies of AI Business" held on May 5, 2022 in the BIRD incubator. "Ladies of AI Business" is the AI edition of the long-standing conference "Ladies of New Business" organized by Netokracija and, as the name suggests, is dedicated to the world of artificial intelligence and machine learning.
Katarina’s lecture focused on her doctoral research on multi-agent systems for providing services based on user preferences in the Smart Space of the Internet of Things. She explained with interesting examples how to use Software Agents to adapt the ambient conditions in the space to the preferences of users, without user intervention, even if it is necessary to meet the preferences of multiple users living in the same space. In addition, she presented the Laboratory for Internet of Things and the IoT field and IoT4us projects.

At the workshop, he presented the paper "Survey on Low Power Wide Area Networks in IoT" by Damjan Katušić, Pavle Skočir, Mario Kušek and Igor Čavrak. The focus of the presentation was on communication technologies and their potential for application in agriculture, which is very important for the outcome of the IoT-field project.
Denis Salopek, member of the IoT4us research team and FER doctoral student, participated in the recently completed Google Summer of Code cycle, during which he successfully completed a device driver development project at the core of the FreeBSD operating system for the NetFPGA SUME development board. We will use the aforementioned NetFPGA SUME driver and development board as part of the IoT4us project to research, design, and develop security and privacy mechanisms in Internet of Things environments.
Denis has successfully developed a suitable driver for the FreeBSD operating system, and it's an even bigger success that the developed driver will be included in the upcoming version of the FreeBSD 12.2 operating system. Congratulations to Denis for this significant achievement!
At the 14th KES International Conference, KES-AMSTA 2020, held online from 17 to 19 June 2020, the paper "Agent-Based Approach for User-Centric Smart Environments" by Katarina Mandarić, Pavle Skočir and Gordan Ježić was presented.
The paper describes a Cognitive Internet of Things system in a smart home on the example of intelligent lighting management realized through two different approaches: an agent approach and a centralized approach. In both approaches, feed-forward artificial neural networks are trained under supervision and used to adjust the lighting conditions to the specific user.

The beginning of this year has marked the start of a new project in the Internet of Things Lab, "IoT4us: Human-centric (smart) services in interoperable and decentralised IoT environments". The project is funded under the "Research Projects" program of the Croatian Science Foundation (CSF) for the period of 4 years, until 31.12.2023. The project leader is Prof. Ivana Podnar-Zarko. The research group is currently composed of 10 researchers from UNIZG-FER, both professors and doctoral students, and we expect to expand the team with two additional PhD students and one postdoc during the project lifetime.
The IoT4us project is adopting and building upon cutting-edge results of the H2020 symbIoTe project which has developed an open source middleware for IoT interoperability and established an initial ecosystem of interoperable IoT platforms steering a new wave of innovative IoT applications and services across domains and platforms. IoT4us will evolve this ecosystem further to create decentralised, dynamic, secure and privacy-preserving IoT environments that, in addition to cloud resources, also rely on edge (and fog) computing resources. IoT4us will enable human-centric, autonomous and cognitive IoT services within such environments to facilitate either knowledge creation from heterogeneous IoT data sets or to initiate actions based on user preferences and past behaviour. The performed research will contribute to the emergence of next-generation IoT solutions adequate to be incorporated into 5G networks with a primarily goal to offer usable, intelligent, secure and privacy-preserving applications and services for end users. Through its research objectives, the project will investigate the following challenging topics: dynamic, decentralized and interoperable IoT ecosystems with secure communication mechanisms, communication protocols for efficient data transmission in Low-Power Wide-Area networks, intelligent and cognitive services for interoperable IoT ecosystems, Blockchain technology and privacy-preserving mechanisms for IoT.
The first project meeting was held on February 17, 2020. A public presentation of the project was planned to be held on March 25, 2020 in the Gray Hall at UNIZG-FER as a part of the presentations of all new projects funded by the Croatian Science Foundation which are lead by UNIZG-FER, but it was postponed due to the Covid-19 pandemic.
