Researchers have developed a novel approach to enhance secrecy energy efficiency in low-altitude wireless communications by integrating unmanned aerial vehicles (UAVs) with intelligent reflecting surfaces (IRS). The proposed method formulates a complex optimization problem to maximize secrecy energy efficiency, involving beamforming, IRS phase shifts, and UAV trajectory. To solve the UAV trajectory optimization, a Dueling Double Deep Q-Network with Prioritized Experience Replay (D3QN-PER) algorithm was introduced, which reportedly offers improved convergence and stability over traditional Deep Q-Networks.
