DIFF-TRO: A Self-Supervised Diffusion Framework for IoT Topology Robustness Optimization

The robustness of Internet of Things (IoT) topologies, which measures a network’s tolerance to node removals, is critical to maintaining stable network connectivity. Existing robustness optimization methods mainly rely on search-based heuristics, which suffer from path dependence and often converge to suboptimal topolo...

RoVi: Robust Vital Sign Reconstruction With Generative AI Under Irregular Body Motions

Wireless vital sign sensing extracts respiratory features from signal phase variations induced by chest movements. However, motions of other body parts produce superimposed signals, resulting in indistinguishable anomalous segments that obscure respiratory extraction. Existing approaches primarily rely on regular motio...
