Project Duration

01.01.2024 – 31.12.2025

Located at



An overwhelming need for data transmission in a globalised world calls for massive innovations in the design of future networks. The project aims to contribute to this via the rigorous analysis of detection and contact times in complex networks featuring
realistic mobility and multifaceted sources of randomness.
