Research days: Multi-UAV systems

Autonomously flying robots — also called small-scale unmanned aerial vehicles (UAVs) — are more and more exploited in civil and commercial applications for monitoring, surveillance, and disaster response. For some applications, it is beneficial if a team of coordinated UAVs rather than a single UAV is employed. Multiple UAVs can cover a given area faster or take photos from different perspectives at the same time. This emerging technology is still at an early stage and, consequently, profound research and development efforts are needed.

Wirtschaftsblatt: Smart network for factory halls

Metal parts in factory halls disturb wireless communications. ICT researchers from Klagenfurt invented a new transmission technique and are now looking for partners for implementation. Although the need for fast and reliable data transmission via WLAN increases in production halls, the technology is still limited. Mobile machinery, forklifts, and robots disturb the radio link between transmitter and receiver. Wolfgang Rössler reports.

UNIsono interviews Bettstetter

As part of a new series on research excellence, Romy Müller from the university magazine UNIsono recently interviewed Christian Bettstetter. “You have to enjoy research, be diligent and lucky to achieve success in science,” Bettstetter says. Good MSc graduates are recommended to target a PhD to later on have the choice to either stay in academia or find a job in industry. He decided to become a professor as he also enjoys teaching and the academic freedom. Read online or download:

Der Standard: Car 1 to Car 2

Researchers at Klagenfurt’s Lakeside Labs work on self-organizing wireless networks which should eventually allow communication between vehicles. Günther Brandner was interviewed by Markus Böhm from the Austrian daily newspaper Der Standard. “Cars are already computers on wheels. We just need to make them talk to teach other,” he says. The team is currently testing the performance of protocols in real-world road traffic which provides new insight on how to optimize them. Read online or download:

Kleine Zeitung: “Jam after accident!”, one car warns the other

Freezing rain causes an accident on a highway. Sensors attached to cars detect this event and communicate it via WLAN to other cars to inform oncoming drivers. The implementation of new WLAN technologies for car-to-car communication is running at full speed. Bettstetter and his team have also been tackling this problem. Their key ideas lead to filing two patent applications. Esther Farys reports. Download article:

Der Standard: Let’s do it like the ants

Engineers are trying to exploit the behavior of insect swarms for the design of socio-technical systems. Experts from ten countries and various disciplines are currently discussing this field of research during the Research Days hosted by Lakeside Labs in Klagenfurt. Concepts from self-organization should be applied, for example, to future mobile communication networks and energy grids. Peter Illetschko reports. Read online or download: Photo: picturedesk.com

Der Standard interviews Bettstetter

Information and communication systems become increasingly complex. Sascha Aumüller from the daily newspaper Der Standard talked with Christian Bettstetter about this problem. The interview “Nobody likes to call the sysadmin” is about self-organization that can help to overcome the limitations of today’s technological possibilities. Lakeside Labs founder Bettstetter also talks about his current projects and Klagenfurt as a science location. Read online or download:

Joining forces against radio silence

The newspaper Der Standard reports in its weekly science and technology section about cooperative relay communications in wireless systems. Based on an interview with Christian Bettstetter, the article “Gemeinsam gegen die Funkstille” explains that mobile devices could help each other to achieve higher energy efficiency and better radio coverage.
