Green Emergency Communications in RIS- and MA-Assisted Multi-UAV SAGINs: A Partially Observable Reinforcement Learning Approach

Experimental results show the spatiotemporal A2C policy outperforms IA2C, ConseNet, FPrint, DIAL, and CommNet, achieving faster convergence, higher asymptotic reward, reduced temporal-difference(TD), advantage estimation errors, and a better communication throughput–energy trade-off.
