If you are interested in writing a diploma or do a research under my supervision, then please check here what in general are the topics that we cover in my lab. Lately, we especially focus on the Internet of Things topics. See [here] for details.
You are also welcome to propose your own ideas. For the diploma work most important think is to show your ability to apply the knowledge from your studies to resolve particular problems.
For more details, please come to my office during contact hours or make an appointment.
