Toward Robust IoT Device Authentication: Cross-Day Specific Emitter Identification via Domain Adaptation

Qi Wu, Qun Wan, Guan Gui, Hien Quoc Ngo et autres

Specific emitter identification (SEI) exploits device-dependent RF fingerprints to distinguish individual transmitters and is important for securing large-scale Internet-of-Things (IoT) deployments. While deep SEI can achieve near-perfect accuracy under same-day evaluation, real deployments rarely satisfy this assumption. At scale, per-day labeling is …

QoE-Oriented Streaming Power Allocation in LEO Satellite Networks

Huazhi Feng, Feng Wang, Junyu Lai, Qi Wu et autres

Low Earth Orbit (LEO) satellite networks are expected to support global multimedia services in future sixth-generation (6G) systems, where streaming media constitutes a major traffic type with stringent Quality of Experience (QoE) requirements. However, existing satellite resource allocation schemes mainly optimize Quality …

Joint Optimization of Computation Offloading and Service Caching for Satellite Edge Networks

Qi Wu, Lidong Zhu

The limited onboard caching and computing resources significantly constrain the computational service capabilities of individual satellites in hotspot regions. To address this challenge, this paper proposes a joint optimization scheme for computation offloading and service caching under edge computing satellite service deployment …
