Networked systems: Wireless connectivity and self-organization.
Interconnected devices and the emergence of autonomous cyberphysical systems are increasingly shaping our lives. It is this rapid technological-societal change that drives the work of Bettstetter and his team. Their research encompasses the design, modeling, and analysis of novel techniques for wireless connectivity and distributed control in networked systems with application to telecommunications, IoT, robotics, and transportation.
The portfolio covers a broad spectrum of expertise, including stochastic modeling and analysis, distributed algorithms and protocols, simulation and performance analysis, prototyping on programmable hardware, and wireless and robotic experiments. Theoretical work uses methods from stochastic geometry, queuing theory, and random graphs. A special emphasis is given to applying principles of self-organization from nature to technical systems.
Current activities focus on interference in wireless systems, network synchronization, reliability of sensor networks in industrial environments, design and experimental evaluation of autonomous networked drones, and optimization of autonomous transport systems. The group is part of the university’s doctoral school on networked autonomous aerial vehicles and its interdisciplinary cluster on self-organizing systems. Several projects are funded by highly competitive grants.
