Enhancing Reliability in IoT Communications via UAV-Based Decode-and-Forward Relaying
摘要
The work analyzes a dual-hop UAV-assisted IoT system using the decode-and-forward protocol. The wireless channel is modeled with the Generalized-K distribution to account for multipath fading, shadowing, and atmospheric loss. A closed-form expression for the channel gain PDF enables accurate BER analysis. Results, supported by Monte Carlo simulations, show that higher IoT device density improves communication reliability, offering key insights for robust UAV-IoT network design.
