Airborne Particle Communication Through Time-varying Diffusion-Advection Channels
Fatih Merdan, Ozgur B. Akan
Particle-based communication using diffusion and advection has emerged as an alternative signaling paradigm recently. While most existing studies assume constant flow conditions, r…
Deadline-Bound Finite-Object Delivery over Intermittent LEO Satellite Contact Plans under Residual-Service Accounting
Houtianfu Wang, O. Tansel Baydas, Hanlin Cai +2
Low-Earth-orbit (LEO) relay networks deliver finite objects -- sensing tiles, telemetry blocks, model updates, and checkpoints -- over intermittent inter-satellite and space-to-gro…
Edge-Side Fingerprints of Service Tiering and Quota Throttling in Starlink
Houtianfu Wang, Hanlin Cai, Haofan Dong +1
We design and evaluate an edge-side measurement procedure for auditing service tiering and quota-based throttling in Starlink. Using a 232.8-hour plan-hopping campaign on a UK resi…
Access Selection for Finite-SNR Modal Recoverability in Sampled-Wave Receivers
Shaojie Zhang, Ozgur B. Akan
Large-aperture wave receivers can contain a large number of candidate sensor locations, antenna ports, or measurement blocks, while hardware and processing constraints allow only a…
Acoustic, VOC, and Multimodal Stress Source Localization in the Internet of Plants
Ahmet B. Kilic, Ozgur B. Akan
The Internet of Plants (IoP) treats distributed plant networks as bio-sensing infrastructure for environmental monitoring, but spatial localization of stress sources within such ne…
A reversed solar illumination dependence of unintended emission from Starlink Direct-to-Cell satellites at 72-234 MHz with the EDA2
Haofan Dong, Houtianfu Wang, Hanlin Cai +1
Second-generation Starlink Direct-to-Cell (DTC) satellites carry an additional payload for direct cellular phone connectivity whose unintended electromagnetic radiation (UEMR) at s…
