摘要
针对无人飞行器Ad Hoc网络仿真研究中的不足,提出了一种基于多分辨率建模的分布交互式仿真方法,利用元建模技术拟合高分辨率模型的输入/输出关系,对得到的元模型族进行适当裁剪和组合构造低分辨率模型,满足了多分辨率模型间的行为层次一致性。采用HLA高层体系结构,以KD-RTI为运行支撑环境实现了仿真原型系统。在想定场景下进行了无人飞行器Ad Hoc网络性能优化,实验结果表明,多分辨率建模提高了仿真效率,满足仿真优化应用的需求。
To deal with the disadvantage in the UAVs Ad Hoc network simulation, a distributed interactive simulation framework based on multi-resolution modeling was proposed. The I/O relationship of high-resolution model was fitted with metamodeling technique, and the low-resolution model wasbuilt with tailoring and combining of the metamodel family. The metamodeling technique maintained the behavior layer consistency among the models in different resolutions. Prototype system was developed based on the High Level Architecture and KD-RTI, the network performance was optimized in the predefined scenario. The experiment result shows that the simulation efficiency is improved with multi-resolution modeling which can meet the requirement of UAVs Ad Hoc network simulation.
