The field of low-altitude wireless networks is moving towards integrating unmanned aerial vehicles (UAVs) with reconfigurable intelligent surfaces (RIS) and other technologies to enhance security, efficiency, and coverage. Researchers are exploring collaborative beamforming, secure communication frameworks, and joint optimization of UAV and RIS parameters to address critical issues such as signal attenuation and security vulnerabilities. Noteworthy papers include: STAR-RIS-assisted Collaborative Beamforming for Low-altitude Wireless Networks, which proposes a heterogeneous multi-agent collaborative dynamic optimization framework to maximize transmission rate and minimize energy consumption. When UAV Swarm Meets IRS: Collaborative Secure Communications in Low-altitude Wireless Networks, which presents a novel secure communication framework using a virtual antenna array and IRS to create a robust defense against eavesdropping attacks. Low-Altitude UAV-Carried Movable Antenna for Joint Wireless Power Transfer and Covert Communications, which proposes a mixture-of-experts-augmented soft actor-critic algorithm to jointly maximize harvested energy and sum achievable rate while minimizing propulsion energy consumption.
