一种基于网格的DDM区域匹配算法

A Grid-Based Region Matching Algorithm of DDM

在大规模分布式交互仿真中,数据分发管理(DDM)的重要功能是减少联邦成员接收不相关数据,实现数据过滤。它允许联邦成员在路径空间中通过更新区域或订购区域表达它们要发送或接收数据的范围,通过区域匹配运算确定数据供求关系,实现数据过滤。其关键是如何减少需要匹配的区域,以减少区域匹配运算量,文章以此为目的,提出一种基于网格的区域匹配算法。

In large distributed interactive simulation,the function of DDM is reducing the irrelevant data received by federates to realize data filtering.It allows each federate to declare its publishing regions and subscription regions in a routing space.Through region matching,DDM determine the supply and demand relationship betweem federates.The crux is how to reduce the candidate regions that need to calculate.Based on it,this paper proposes a grid-based region matching algorithm of DDM.
