Island-Ready Communication Networks: Connectivity Monitoring and State Synchronization for 5G Crisis Connectivity at the Edge
Leon Janzen, Maria Koch, Matthias Hollick
Island-ready 5G deployments provide edge connectivity for isolated regions in crisis scenarios by switching to island operation when they are cut off from the global Internet. This…
Extended Version: Measuring the End-to-End Resilience of Application Deployments in Real-World Communication Networks with DRACO
Leon Janzen, Matthias Hollick
Billions of users take Internet connectivity for granted and use it daily to access applications deployed anywhere around the globe. What users perceive as a seamless connection be…
Fault-Aware Design for Reconfigurable Holographic Surface-Aided ISAC Systems
Lu Wang, Mohamadreza Delbari, Gui Zhou +3
Reconfigurable holographic surface (RHS)-aided integrated sensing and communication (ISAC) systems hold great promise for achieving both sensing and communication with low hardware…
Transparent and Resilient Activity Recognition via Attention-Based Distributed Radar Sensing
Mina Shahbazifar, Zolfa Zeinalpour-Yazdi, Matthias Hollick +2
Distributed radar sensors enable robust human activity recognition. However, scaling the number of coordinated nodes introduces challenges in feature extraction from large datasets…
Making Cellular Networks Crisis-Proof: Towards Island-Ready, Resilient-By-Design 6G Communication Network
Leon Janzen, Matthias Hollick
5G and 5G-Advanced cellular networks are vulnerable to regional outages resulting from disasters or targeted attacks. This fragility stems from the reliance on the central core net…
