Deadlocks in the synchronization of oscillators
Certain oscillator networks suffer from deadlocks that prevent them from synchronizing. We derived the likelihood for such constellations in star graphs and found that they also occur in random graphs.

Multi-drone systems: Embedded wireless sensor networks in the air
Drones that sync and swarm
Scientists of the doctoral school “Networked Autonomous Aerial Vehicles” implemented a self-adaptive swarm of drones and showcased it in Klagenfurt’s new drone hall, one of the largest and most modern facilities of its kind.
Workshop on scientific writing
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.
Using cellular networks for drones
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.
Research days: Communication in swarms
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.
Panel: 5G opportunities and challenges
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.
Unmanned aerial vehicle communications: Opportunities and challenges
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.
“Drones are here to stay. Get used to it.”
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.
Robots that sync and swarm: A proof of concept in ROS 2
The swarmalator model for systems in which synchronization and swarming are coupled is implemented and studied for the first time in a technical system.
