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…

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…

Modeling protocols in relay networks with Markov chains

Wireless communications often suffers from error bursts — a long sequence of bits is corrupted when being transmitted over the air. A relatively new technique that tries to mitigate this unreliability is cooperative relaying. Its basic idea is simple: When a device transmits data packets to a destination, adjacent devices can overhear these packets. If…

Successful completion of cDrones

The Lakeside Labs project cDrones started in 2008 as an effort of four Klagenfurt professors to work on system-level aspects of small-scale unmanned aerial vehicles for application in disaster management. Using off-the-shelf, low-altitude multicopters equipped with high-quality cameras and GPS, the project team developed a software that enables an autonomous system for aerial reconnaissance. The…

Project kickoff: Decision making in networks with errors

The Lakeside Labs project SOSIE takes an interdisciplinary perspective on decision making in networks suffering from information errors. Human organizations and technical communication systems are compared to identify similarities and differences during decision making processes. Successful techniques may then be transferred from one discipline to the other. Friederike Wall, who initiated the project together with…

Colloquium in honor of Eberspächer

A scientific colloquium in honor of Jörg Eberspächer was held at Technische Universität München on December 7, 2012. Eberspächer founded the Institute of Communication Networks in 1990 and retired as professor emeritus some weeks ago. The responsibilities were handed over to his successor, Wolfgang Kellerer, a PhD graduate of Eberspächer and then senior manager at…

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…

FWF project on interference in wireless networks

Multiple-access interference in wireless networks has significant impact on diversity techniques and protocols. Bettstetter and Schilcher aim at gaining a deeper understanding of interference dynamics and to rigorously analyze its impact on system performance. They secured funding by the Austrian Science Fund (FWF) in the order of 350.000 EUR for their new project INDY. “The…

Synchronization in networks with stochastic interactions

Synchronization emerges in a variety of systems ranging from fireflies and neural networks in biology, to coupled lasers, wireless communication, and Josephson junctions in physics and engineering. Sometimes the goal is to avoid synchrony, e.g., during Parkinson tremor or epileptic seizures, sometimes to achieve synchrony, e.g., in heart pacemakers, lasers, electric power grids and communication…

Aerial imaging with small UAVs

The cDrones team at Lakeside Labs, Klagenfurt, develops a system for multiple unmanned aerial vehicles (UAVs) to provide a high-quality aerial overview image of a given area of interest. Evsen Yanmaz explains: “It only takes a few mouse clicks for operators to define the area to be observed. To provide for autonomous coverage of the…
