Hide and Seek in Embedding Space: Geometry-based Steganography and Detection in Large Language Models
Charles Westphal, Keivan Navaie, Fernando E. Rosas
Fine-tuned LLMs can covertly encode prompt secrets into outputs via steganographic channels. Prior work demonstrated this threat but relied on trivially recoverable encodings. We f…
Power Efficient IRS-Assisted NOMA
Jianyue Zhu, Yongming Huang, Jiaheng Wang +2
In this paper, we propose a downlink multiple-input single-output (MISO) transmission scheme, which is assisted by an intelligent reflecting surface (IRS) consisting of a large num…
Provisioning Energy-Efficiency and QoS for Multi-Carrier CoMP with Limited Feedback
Mohammad G. Khoshkholgh, Victor C. M. Leung, Kang G. Shin +1
We consider resource allocation (RA) in multi-carrier coordinated multi-point (CoMP) systems with limited feedback, in which a cluster of base stations (BSs), each equipped with mu…
Coverage Performance of Aerial-Terrestrial HetNets
M. G. Khoshkholgh, Keivan Navaie, Halim Yanikomerogluy +2
Providing seamless coverage under current cellular network technologies is surmountable only through gross overengineering. Alternatively, as an economically effective solution, th…
Randomized Caching in Cooperative UAV-Enabled Fog-RAN
M. G. Khoshkholgh, Keivan Navaie, Halim Yanikomerogluy +2
We consider an unmanned aerial vehicle enabled (UAV-enabled) fog-radio access network (F-RAN) in which UAVs are considered as flying remote radio heads (RRH) equipped with caching…
How Do Non-Ideal UAV Antennas Affect Air-to-Ground Communications?
M. G. Khoshkholgh, Keivan Navaie, Halim Yanikomeroglu +2
Analysis of the performance of Unmanned Aerial Vehicle (UAV)-enabled communications systems often relies upon idealized antenna characteristic, where the side-lobe gain of UAVs' an…
Caching or No Caching in Dense HetNets?
M. G. Khoshkholgh, Keivan Navaie, Kang G. Shin +2
Caching the content closer to the user equipments (UEs) in heterogenous cellular networks (HetNets) improves user-perceived Quality-of-Service (QoS) while lowering the operators ba…
MR-BART: Multi-Rate Available Bandwidth Estimation in Real-Time
Mahboobeh Sedighizad, Babak Seyfe, Keivan Navaie
In this paper, we propose Multi-Rate Bandwidth Available in Real Time (MR-BART) to estimate the end-to-end Available Bandwidth (AB) of a network path. The proposed scheme is an ext…
