Trust Management in Social Internet of Things | Barbora Buhnova

May 04, 2023 | 4:00 PM CET

About Topic: Digitalization is leading us towards a future where people, processes, data and things are not only interacting with each other, but might start forming societies on their own. In these dynamic systems, converging towards Social Internet of Things (SIoT), trust management on the level of human-to-thing as well as thing-to-thing interaction becomes an essential ingredient to supervise safe and secure progress of our digitalized future. In this talk, we will look into the essential elements of trust management in complex digital ecosystems and SIoT, including trust assessment and its influencing factors (e.g., feeling vulnerable), trust propagation (e.g., via reputation), and trust updates (e.g., via dynamic certification schemes). We will give an overview of the current open discussions about the trust management strategies and discuss their risks and related trust attacks (e.g, self-promotion or whitewashing).

Sunlight for wireless communication | Marco Zúñiga

Apr 06, 2023 | 4:00 PM CET

About Topic: We, humans, already use 50% more energy moving information than moving airplanes around the world. Communication is central to our societies but is taking a toll on the earth. We want to use a free, abundant, and natural resource for wireless communication: sunlight. Similar to the way you can use a mirror to communicate by reflecting light, our aim is to change the surfaces of objects to control their reflection properties to send information, but without noticing any flicker! In this manner, objects will be able to talk to each other using daylight, an eco-friendly solution. In this talk, we will present some of our recent work on this exciting area and its potential applications. A world that communicates through natural light. That’s the goal.

The IoT and the two sides of Sustainability | Carlo Boano

Mar 02, 2023 | 4:00 PM CET

About Topic: IoT systems are often portrayed as a key driver for sustainability and as an essential technology to achieve many of the seventeen United Nations’ sustainable development goals by 2030. Among others, IoT systems can help improving health and well-being, building smart cities, promoting a responsible production and consumption, increasing awareness and visibility into energy and resource usage, as well as facilitating access to clean energy. At the same time, sustainability is often not a concern during the design of an IoT system: several IoT gadgets are unnecessary, many IoT products become quickly obsolete, and poorly-performing IoT devices are quickly dismissed. As a result, IoT hardware often ends up as e-waste into landfill after a very short lifespan, which is worrying considering the magnitude of IoT devices expected in the next decade. In this talk, I will illustrate this paradox with concrete examples and highlight the need to maximize the usability and lifetime of IoT systems, presenting technical solutions that could help in this regard.

About Speaker: Carlo Alberto Boano is an associate professor at the Institute of Technical Informatics of Graz University of Technology (TU Graz), Austria. He received the Venia Docendi in “Embedded Systems” from TU Graz with an Habilitation thesis entitled “Technologies and Tools for the Design of Dependable Networked Embedded Systems” in 2020.

Low Power Wide-Area Wireless Internet of Things with LoRaWAN | Dirk Pesch

Jan 05, 2023 | 4:00 PM CET

About Topic: Connectivity, particularly wireless connectivity, is a key enabling technology for the Internet of Things. A plethora of technologies exist, ranging from short-range to long-range and low to medium power options. Recently, long-range, low-power wireless communication technologies have been introduced for both licensed and unlicensed radio spectrum. Unlicensed spectrum technologies such as LoRa/LoRaWAN have become very popular because of their low cost, open standard and open-source software support. However, the current standard has many weaknesses in supporting a vision of dense, wireless IoT device deployment. In this talk, we will briefly review long-range, low-power wireless technologies, review some of the weaknesses of LoRaWAN and present a range of advances that address these weaknesses; in particular, we will focus on medium access fairness, power efficiency and delay performance for both terrestrial and satellite-based smart city and industrial IoT applications.

LoRa-DTN: Tailor-made IoT platform for extreme Arctic conditions | Samo Grasic

Dec 01, 2022 | 4:00 PM CET

About Topic: This seminar will engage in the lessons learned from designing, developing and deploying the LoRa-DTN IoT platform. This platform was tailor-made by and for the Sami reindeer herding population in the north of Sweden. Due to the harsh Arctic winter conditions, lack of power and internet infrastructure, remoteness and inaccessible terrains, conventional off-the-shelf IoT solutions were not applicable. Hence, the LoRa-DTN platform was developed in order to provide reindeer herders ability to track their reindeer herds, exchange short messages, use drones as a data relay and monitor the ice thickness on lakes during winter time. The platform is built on a custom hardware and employs LoRa radios and custom-built network protocol based on the Delay Tolerant Network architecture (using Store-And-Forward principle).

About Speaker: Since 2016, Samo Grasic has worked at Dálvvadis economical association, Jokkmokk, where he designs and develops the Nomatrack LoRa-DTN (Delay Tolerant Network) platform. This platform is tailor-made for reindeer herding purposes in remote Arctic environments. Samo is the member of the The Inter Planetary Networking Special Interest Group and the co-author of the PRoPHET routing protocol (RFC 6693). Samo received his PhD from Luleå University of Technology, in the subject of of Human Work Science, in 2014. Here, focus ison development and deployment of the ICT infrastructure DTN for sparsely populated Arctic regions. Samo’s interests include routing in computer networks, energy harvesting, low power systems, soft, and hardware development as well as embedded systems. Samo is also interested in the social, and economical aspects of ICT deployments. Prior to his academic career, Samo worked for more than six years in the industry, developing hardware and software components for meteorological and radiological systems.

Toit, a modern framework for IoT | Florian Loitsch

Nov 03, 2022

About Topic: Modern microcontrollers, like the ESP32, are more powerful than the first Unix machines. Despite their speed, they are still treated like 8-bit microcontrollers from the 90s: by flashing monolithic applications on them. Individual components have no protections from each other, and the development process is brittle, since a change or bug in one part of the firmware could adversely affect the rest. This doesn’t need to be. In this presentation we will present Toit. A modern framework for IoT devices. A new language, virtual machine, and lots of libraries, work together to provide a great development experience with properties we generally expect from operating systems: memory separation, individual applications, ease of use with a high-level garbage-collected language, and fast development iterations.

About Speaker: Florian Loitsch did his PhD in compiler technologies, compiling Scheme to JavaScript. He was then hired by Google to work on V8 (Chrome’s JavaScript engine). He was part of the team that developed the Dart programming language, for which he was the technical lead for the Dart-to-Javascript compiler and later for the Dart libraries. Almost 5 years ago, he co-founded Toitware, where he has been developing and improving Toit since.
