针对用户星数据中继接入请求超额定购问题,分析了用户星业务种类,研究了中继卫星接入控制所受多类约束的特点,建立了约束满足模型;以接入业务总优先级权值最高为原则,根据业务的类型、时间有效性和业务优先级设置链路接入灵活度和业务冲突集,以业务的接入顺序和选择接入的中继星链路为优化对象,提出了一种基于业务类型和自适应小窗口蚁群算法双层优化的中继卫星混合链路接入控制算法。仿真实验表明,所建模型可实现多类型业务与多种类天线的接入控制,提出的双层优化算法较单层寻优效果更佳,且具有较快的收敛速度和较强的全局优化能力,因而所提算法可有效解决多约束条件下多业务类型、多种类天线和多中继星的接入控制问题。
Aiming at the over subscription problem of subscriber star data relay access requests, the types of subscriber star services are analyzed, and the characteristics of many kinds of constraints imposed by relay satellite access control are studied. The constraint satisfaction model is established. According to the principle of the highest value, the link access flexibility and service conflict set are set according to the service type, time validity and service priority, and the service access sequence and the selected access star link are optimized. A Hybrid Optimal Access Control Algorithm for Trunked Satellite Based on Service Type and Adaptive Small-window Ant Colony Algorithm. Simulation results show that the proposed model can achieve access control for multiple types of services and multiple types of antennas. The proposed two-layer optimization algorithm is better than single-layer optimization and has faster convergence rate and better global optimization ability , The proposed algorithm can effectively solve the access control problem of multi-service type, multi-types of antennas and multi-relay star under multi-constraint conditions.
