摘要
该文总结了高层体系结构(HLA/RTI)中数据分发管理(DDM)目前常用的几种机制,并分析对比了它们各自的优缺点。在此基础上给出了基于网格技术的最优网格的数据过滤机制(Best-G rid-Based F iltering)的实现方法,给出了它的理论模型及其计算公式,并将这种数据过滤机制运用于森林协同灭火子系统中。通过试验验证,最优网格数据过滤机制实现了高层体系结构中数据分发管理在局域网上数据过滤的高效性,有效地减少了网络的冗余负载量提高了带宽的有效利用,进而满足了交互仿真的实时性与逻辑正确性。
In this paper, we discuss several basic data distribution management mechanisms of HLA/RTI, compare their advantages and disadvantages. Then a data distribution strategy is proposed, a DDM model named the Best - Grid Filtering mechanism is developed and the way of how to computer the appropriate size of Grid - Cell is given. Then this filtering mechanism is used for the system of forest fire fighting. Through the test, this mechanism realizes the purpose of the data distribution management in the local network by reducing the quantity of the data, and meets the demands of the real - time and the logic correction in the distribute simulation.
