In its final year, UnderSec is bringing these strands together into a layered approach to underwater threat detection and decision support. At the outer layer, optimised networks of range‑free sensors...

Over the past year, UnderSec partners have assembled a complete toolbox to detect, track and understand activities around critical and underwater infrastructures. The project started by looking at how...

Many optimisation methods for wireless sensor networks are tested on large scenarios where the true best solution is unknown. In contrast, this article deliberately uses a small‑to‑medium test case...

The study focuses on range‑free, angular‑limited sensors that only measure the direction of incoming signals, not their distance. This is highly relevant for UnderSec scenarios where inertial or...

UnderSec relies on networks of sensors to detect and localise unknown transmitters around areas of interest, including critical and underwater infrastructures. In many cases, not all installed sensors...

Before CMIM can be deployed operationally, its performance needs to be validated under controlled but realistic conditions. The team carried out laboratory experiments in a water basin using simulants...
