Open theses and practical projects on mobile networked systems topics.

In case of interest, feel free to contact me at karin_anna.hummel@jku.at (in the initial meeting/information exchange, we will discuss details about the topics).

Crowd devices Disrupted and degraded connectivity: For many services, high-quality Internet access is assumed to be available 24/7. Yet, in areas where (mobile) access networks are not available or provide only limited quality such as in remote regions (mountains, at sea, rural areas), after a disaster, or in space, connectivity cannot be taken for granted. To provide services nevertheless, ad-hoc wireless connectivity is needed. Communication technologies targeted are optical communications, Bluetooth/BLE or Wi-Fi (smartphones, connected vehicles, etc.) and, e.g., pre-fetching of data and caching may be leveraged. In this frame, we will work on advancing mobile apps, distributed algorithms, and network protocols.
UAV Timing and performance aspects of unmanned aerial vehicles (UAVs) aka drones: UAVs operate in 3D with a certain level of autonomy. To form multi-drone and human-drone teams, it is necessary to understand the timing aspects (delays) in these cyber-physical distributed systems in order to provide proper control rules. One aspect of particular interest is the anticipated drone movement in the near future.
Network Performance Mobile network performance measurement, prediction, and use for optimization: this topic focuses on providing tools to measure, log, process, visualize wireless networking conditions on the move (5G, Wi-Fi, LoRaWAN, etc.) and to apply prediction to network protocols and networked services.
