Abstract: This report focuses on the technological challenges of integrated air-space-ground systems for the low-altitude economy, conducting research around UAV networking and management, computing power optimization, collaborative deployment, and hybrid heterogeneous scenarios. In terms of networking and management, a secure routing scheme based on an improved artificial bee colony algorithm combined with blockchain is proposed, constructing a five-layer flying social network architecture and ensuring transmission and computing reliability through software-defined networking (SDN). For computing power optimization, an SDN-assisted computation offloading architecture and UVCO algorithm are designed, alongside the development of a DDPG-based adaptive emergency deployment scheme, integrating digital twins for dynamic trajectory planning. At the collaborative deployment level, wireless power transfer strategies are established, a GREEN energy efficiency maximization scheme is proposed, and energy-saving data collection and RIS-assisted coverage mechanisms are developed. Addressing hybrid heterogeneous scenarios, core challenges such as airspace planning are identified, and decentralized federated learning based on low-earth orbit satellites and region-partition adaptive offloading algorithms are proposed. Related outcomes support the low-altitude control platform in achieving device compatibility and digital twin interaction, laying a foundation for the large-scale application of the low-altitude economy.
