SkyTrust: Blockchain-Enhanced UAV Security for NTNs with Dynamic Trust and Energy-Aware Consensus
Afan Ali, Irfanullah Khan
Non-Terrestrial Networks (NTNs) based on Unmanned Aerial Vehicles (UAVs) as base stations are extremely susceptible to security attacks due to their distributed and dynamic nature,…
TinyML-Based Adaptive Pulse Shaping for Edge Intelligence in IoT/IIoT
Afan Ali
Edge intelligence in IoT and IIoT demands lightweight algorithms for data processing on resource-constrained devices. This paper introduces a novel adaptive pulse shape filter base…
Spreading the Wave: Low-Complexity PAPR Reduction for AFDM and OCDM in 6G Networks
Afan Ali, Abdelali Arous, Huseyin Arslan
High Peak-to-Average Power Ratio (PAPR) is still a common issue in multicarrier signal modulation systems such as Orthogonal Chirp Division Multiplexing (OCDM) and Affine Frequency…
Stealth Signals: Multi-Discriminator GANs for Covert Communications Against Diverse Wardens
Afan Ali, Md. Jalil Piran, Huseyin Arslan
Covert wireless communications are critical for concealing the existence of any transmission from adversarial wardens, particularly in complex environments with multiple heterogene…
