5G ISAC-Based UAV Detection and 3-D Tracking Using Uplink Sounding Reference Signals on an End-to-End O-RAN Simulation Testbed
Arun K. Gurung, Satha K. Sathananthan, Shiva R. Pokhrel
Integrated Sensing and Communication (ISAC) lets cellular infrastructure serve communication users and sense on the same waveform. We present an end-to-end O-RAN simulation testbed…
Three-Pronged Spectral Control for Federated Parameter Efficient Fine Tuning
Shiva Raj Pokhrel, Dipsan Bhattarai, Anwar Walid
Federated parameter-efficient fine-tuning (PEFT) enables communication-efficient adaptation of large pretrained models on decentralized edge data, but it remains fragile under non-…
A Drift Stable Quantum Federated Learning for Intelligent Services
Shanika Iroshi Nanayakkara, Shiva Raj Pokhrel
Quantum federated learning enables distributed clients to train quantum neural networks without sharing local data, making it promising for privacy-aware intelligent services. Inte…
Small Language Model-based Control for BBR over Low Earth Orbit Satellite Internet
Rakshitha De Silva, Shiva Raj Pokhrel, Jonathan Kua
Low Earth Orbit (LEO) satellite Internet introduces rapid path variability, intermittent capacity shifts, and non-terrestrial delay dynamics that challenge transport-layer congesti…
Unveiling TCP BBR Dominance in Starlink Internet: Experimental Insights and Analysis
Rakshitha De Silva, Shiva Raj Pokhrel, Jonathan Kua
This experimental study delivers a global assessment of Google's Bottleneck Bandwidth and Round-trip propagation time-version 3 (BBR-v3) Congestion Control Algorithm (CCA) over Spa…
HantaWatch: Federated Learning for Hantavirus Genomic Surveillance
Shanika Iroshi Nanayakkara, Shiva Raj Pokhrel
Hantavirus genomic surveillance is limited by the distribution of sequence data, non-IID source heterogeneity, and constrained expert-review capacity. We propose HantaWatch, a fede…
