    AI-Enabled Digital Twin-Driven Handover and Resource Allocation in Multi-LEO Satellite Networks

    Low-Earth orbit (LEO) satellite constellations are emerging as a core enabler of sixth-generation (6G) wireless systems, providing the global coverage and high-capacity connectivity. However, dense multibeam LEO deployments introduce severe interbeam and intersatellite interferences, while rapid orbital motion results in frequent handovers and highly dynamic channels that challenge the real-time optimization. To address these issues, this article has proposed a digital twin (DT)-driven multi-LEO network architecture that integrates the ray-tracing-based virtual simulations with intelligent on-orbit control. Within this framework, we develop a DT-driven efficient handover and multiagent twin delayed deep deterministic policy gradient (DEMAT) scheme, which jointly optimizes beam training, handover, power allocation, and beamwidth adaptation to maximize the energy efficiency (EE) while satisfying user throughput requirements. DEMAT leverages bidirectional DT-LEO parameter exchange and federated-learning (FL)-enhanced agents for cooperative and low-latency resource management. Extensive simulations validate its convergence and scalability under diverse network configurations, such as various time frame intervals and user densities. Notably, DEMAT achieves up to a 59.6% EE improvement over the deep deterministic policy gradient (DDPG) baseline and more than 40% of EE compared with the other DT-based benchmarks, demonstrating superior adaptability and coordination for the next-generation nonterrestrial networks (NTNs).
