Multi-Satellite Collaborative Scheduling Method for Beam Resources with Interference Control
低轨卫星星座的密集部署加剧了波束同频干扰和资源管理挑战.针对非均匀业务分布与有限星载资源的矛盾,提出多星协同波束资源优化方法,通过星群协同调度与功率智能再分配,有效抑制干扰并实现了空闲资源的高效利用,提升了系统容量与业务满意度.首先,建立多星波束间干扰模型;然后,构建波束资源分层协同调度架构,通过星间信息共享、空间隔离约束及负载均衡策略,综合优化波束调度,从而有效抑制干扰并提升系统容量与负载均衡性;最后,针对高纬度波束过饱和问题,提出基于波束关停的功率再分配优化模型,并基于融合改进粒子群与模拟退火的混合算法进行求解,仿真结果验证了所提算法的有效性和高效性.
Resource management has become more difficult due to the increased co-frequency interference between beams caused by the dense deployment of low earth orbit(LEO)satellite constellations.This work presents a multi-satellite collaborative beam resource optimization method to resolve the conflict between limited onboard satellite resources and uneven traffic distribution.The technique successfully suppresses interference and achieves efficient utilization of idle resources through intelligent power reallocation and coordi-nated satellite scheduling,enhancing system capacity and service satisfaction.First,a model of inter-beam interference between mul-tiple satellites is developed.Additionally,a hierarchical collaborative beam resource scheduling architecture is built.The beam schedul-ing problem is thoroughly optimized by utilizing intersatellite information sharing,geographic isolation limitations,and load balancing techniques.This efficiently suppresses interference and improves system capacity and load balance.Lastly,a power reallocation model based on beam shutdown is proposed to address the beam oversaturation problem in high-latitude regions.A hybrid technique that com-bines simulated annealing and improved particle swarm optimization is employed to solve the problem.The usefulness and efficiency of the proposed method are confirmed by the simulation results.
