The following topics are currently offered. If you are interested in writing a bachelor’s or master’s thesis at our chair, please reach out. You can also bring your own topic.
- Location Verification in Car2X Communication, Master Thesis
Cars exchange information with other vehicles, roadside units, or pedestrians and incorporate this data in, e.g., the navigation system. 5G enables such communication in a decentralized way where participants exchange information directly, meaning that no network infrastructure is needed. The correctness of exchanged location information is crucial for reasonable decision-making and a manipulation can affect the safety of participants in the traffic. In this thesis, you implement a simulation model that allows for imitating the exchange of information between mobile participants in traffic. As part of the evaluation, wou implement a verification mechanism that validates the location information of vehicles. - Measuring Mobile Network Infrastructure, Bachelor Thesis
Mobile networks consist of radio towers that provide wireless connectivity, and core networks that are the backbone of the infrastructure. Depending on the commercial operator, the distribution of both radio towers and core networks varies. This not only influences the service that users receive, but can also affect the security and privacy capabilities of the connection. In this thesis, you implement a measurement framework that probes the infrastructures of existing mobile networks. Based on the results of the measurement study, you summarize the results and discuss their implications for the users of the networks. - Setting up an SDR-based 5G UE, Master Thesis
Use one of the existing open-source software stacks to deploy a 5G standalone UE. After setting up the UE, the thesis then focuses on implementing a simple feature in the UE and analyzing its performance in a lab setup of a 5G network. - Implementation of a Signal Strength Measurement App, Bachelor Thesis, Internship
Implement an Android app that allows to measure the signal strength of surrounding mobile network base stations. The thesis includes the design and implementation of the app as well as real-world measurements of signal strengths in an example area. - End-to-End Traffic Analysis Attacks in Mobile Networks, Bachelor Thesis
Design and apply end-to-end traffic analysis attacks on 5G mobile traffic. The thesis focuses on the experimental evaluation of statistical attacks and their feasibility. - Remote SIM Implementation, Master Thesis
Integrate a remote SIM setup into SRSRAN that allows to switch between multiple physical SIM cards within the software stack implementation of SRSRAN. Verify the correct behavior and conduct measurements in this setup.
