Aerial drones connected to cellular networks can affect the throughput of common cell phone users. System-level simulation results were presented at an ACM MobiSys workshop earlier this week.
A new project investigates the integration of unmanned aerial vehicles in 5G networks and proposes a hybrid connectivity solution with Wi-Fi. The work is led by Aymen Fakhreddine and advised by Christian Bettstetter. Funding comes from the Austrian Science Fund (FWF). Written by Christian Bettstetter and Aymen Fakhreddine Wireless connectivity is a fundamental component in drone systems with high demands for reliability, security, and performance. Some drone applications need to transmit huge amounts of data or require ultra-low latencies. The wireless technology used in most commercial drones is Wi-Fi, but it only partially meets the high requirements. Therefore, integrating drones into cellular networks is an exciting option, either as a replacement or supplement to Wi-Fi. A new three-year research project at the University of Klagenfurt addresses this issue. Funding was secured from the Austrian Science Fund (FWF) in the amount of about 288,000 € from the ESPRIT postdoctoral program. The work is embedded into many ongoing activities on multi-drone systems in Klagenfurt (uav.aau.at). “The integration of drones into cellular networks has not yet reached the …
Let’s imagine a large region affected by an earthquake that needs to be combed for missing persons. Because buildings remain at risk of collapsing, this is a task that is particularly well-suited to robots. Micha Sende addressed this kind of scenario in his doctoral thesis. Written by Romy Müller for the University of Klagenfurt.

His research focuses on energy autonomy, asking questions such as: How much energy do I have left? How much energy do I still need to complete a specific task? How long can I continue to work, and when do I need to recharge? Which charging station should I head for, and which one is free at the moment? When asked what makes this task rather complex, Micha Sende answers: “A robotic lawnmower or a robotic vacuum cleaner have a comparatively easy job. They know the territory and they usually work alone, not …
The aviation industry is interested in wireless solutions for in-plane connectivity to improve safety and reduce airplane cost and weight. Ultra-wideband (UWB) seems to be a suitable technology for this purpose due to low power consumption, high data rate, and coexistence with other systems.
Commercial drones usually come equipped with modest on-board computing power. Consequently, their speed and agility are somewhat limited when they use their cameras like eyes to navigate in space. Samira Hayat, a researcher at the Department of Information Technology, recently joined forces with colleagues from other departments and Deutsche Telekom to investigate the effects of offloading computation to the edge of the network (edge computing).
The connectivity of ultra-wideband (UWB) devices is studied in an aircraft assembly hangar and a production hall. These measurements are the first ones reported for off-the-shelf UWB devices in industrial settings and shed light on this technology’s potential to support emerging industrial applications.
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 Barciś is developing new technologies.
A boarding solution for a cable car system that limits the number of passengers allowed to enter a transport cabin has been proposed. Our analysis shows that a shorter waiting time at a particular station worsens the stability of other stations.
A multidisciplinary team at the University of Klagenfurt is due to deliver initial insights on the efficient operation of a drone-based delivery network. Doctoral student Pasquale Grippa will present the results at the Robotics: Science and Systems event taking place at MIT this week.
Lakeside Labs is a non-profit organization for scientific research and development of self-organizing networked systems. Our goal is to apply and improve self-organization in the areas of IoT, robotics and transportation. It has been a successful year.
