The Mobile Systems Group of the University of Klagenfurt held a workshop on scientific writing. They discussed the typical parts of a paper along with specific challenges and practiced them in group work.
It might soon become common for drones to transport goods and people, monitor disaster zones, and bring various forms of relief to areas that are difficult to access. Which communication infrastructure is best suited to facilitate this? Researchers at the University of Klagenfurt have explored potential challenges associated with the use of traditional cellular networks.
A workshop about communication in swarms took place in Klagenfurt in mid-July. Invited speakers and other experts discussed questions at the interface of robotics, distributed systems, and communication technology.
A panel on the next generation of mobile communication systems was held in Klagenfurt. Experts from two network operators, a chip vendor, and research institutions discussed the opportunities and challenges of 5G.
Wireless communications is essential for many applications with commercial drones. Omid Semiari interviewed Christian Bettstetter about this exciting topic at the interface of communications and robotics for the latest IEEE ComSoc TCCN newsletter.
This statement was the title of a TIME article, which was included in the magazine’s special report on “The Drone Age”. We asked Christian Bettstetter to tell us what today’s drones can do and what drone (swarms) are not yet capable of. One thing is certain: Our airspace is going to be much busier in the future.
The swarmalator model for systems in which synchronization and swarming are coupled is implemented and studied for the first time in a technical system.
A transport system with passengers traveling between stations in periodically arriving cabins is considered. We propose and evaluate an access control algorithm that dynamically limits the number of passengers who are allowed to board the current cabin. Simulation of a ski lift using empirical passenger data suggests that such access control can balance out the average waiting times at different stations. The algorithm works well with estimated values of the arrival and de-boarding rates.
The introduction of wireless connectivity in industrial environments promises a rapid and cost-effective reconfiguration of machines and sensors. A key question in this context is: Which wireless technology is best suited for industrial settings? Many of the prevalent technologies, like WiFi and ZigBee, do not meet the requirements of certain industrial applications in terms of data rate, power consumption, and robustness. The lack of alternatives capable of achieving a good balance between these conflicting goals impedes progress. This is why researchers from the University of Klagenfurt, Airbus, and Lakeside Labs investigate the use of ultra-wideband (UWB) communications for wireless connectivity in industrial environments. Interestingly, UWB is commonly used for localization but is not yet an option for communications. Experiments with IEEE 802.15.4-2011 UWB devices were conducted in two industrial scenarios, namely a large-size aircraft assembly hangar and a medium-size production hall. These measurements are the first ones reported for off-the-shelf UWB devices in such setting and shed light on the potential of UWB to support emerging industrial applications. Jorge F. Schmidt, a senior researcher in …
Wherever several clocks tick simultaneously, it is tricky to get them all to display precisely the same time. This can be a challenge for drone swarms that are airborne together. To tackle this problem, young scientist Agata Gniewek is developing new technologies.
