Research Topics

  • Algorithms - Optimium signal processing with low computational requirements: High precision synchronization and localization computed in real-time on low-cost low-power nodes with very limited computational capabilities is still an open task. We investigate efficient computation approaches based on probabilistic models, machine learning strategies for complexity reduction in indoor environments, and alternative sampling approaches.
  • Security - Making the network robust against node failures and external attacks: Cooperation in networks (as needed for decentralized synchronization and localization) requires trustful network members. Exchanging wrong data, which can occur due to node failure or malicious attacks, can disturb the results obtained on each node in the network. We are working on methods that detect disturbing influences and circumvent unwanted effects on the network operation.
  • Implementation - Validation and proof of concept: To fully understand the real-world difficulties of our approaches we provide proof-of-concept solutions in wireless networks. This provides more insight in the problem formulation and enables us to adapt our investigations with limitations observed in operation.
