Securing the Skies: An IRS-Assisted AoI-Aware Secure Multi-UAV System with Efficient Task Offloading
This addresses security and efficiency problems for UAV systems in sectors like agriculture and surveillance, but it appears incremental as it builds on existing DRL methods with transformer enhancements.
The paper tackles data freshness and security issues like eavesdropping and jamming in UAV networks by developing a framework with exponential AoI metrics and secrecy rate, using a transformer-enhanced DRL approach for task offloading optimization, and shows superiority over existing algorithms.
Unmanned Aerial Vehicles (UAVs) are integral in various sectors like agriculture, surveillance, and logistics, driven by advancements in 5G. However, existing research lacks a comprehensive approach addressing both data freshness and security concerns. In this paper, we address the intricate challenges of data freshness, and security, especially in the context of eavesdropping and jamming in modern UAV networks. Our framework incorporates exponential AoI metrics and emphasizes secrecy rate to tackle eavesdropping and jamming threats. We introduce a transformer-enhanced Deep Reinforcement Learning (DRL) approach to optimize task offloading processes. Comparative analysis with existing algorithms showcases the superiority of our scheme, indicating its promising advancements in UAV network management.
