| 摘要: |
| 在分布式仿真系统中，网上流动的大量冗余数据严重影响了系统的可伸缩性。基于均匀网格的相关过滤法减少了冗余数据，但具有匹配不精确，格子尺寸单一，难以适应所有实体的缺点。提出了一种基于多层次网格的相关过滤方法，克服了均匀网格法的上述缺点，并继承了均匀网格法处理速度快的特点，具有快速灵活的特点。 |

| Abstract: |
| In the distributed simulation system, lots of redundant data flowing on the net seriously restricts the system scalability. The relevance filtering base on even-grid reduces the redundant data while it is inaccurate in region matching. Because the sizes of all cells in even-grid are identical, it is difficult to fit all entities in the simulation. A relevance filtering method based on a multi-level grid is put forward which overcomes the above shortcomings and is characterized by agility and speediness. |
