针对HLA数据分发,提出了基于关联规则的动态数据分发策略,主要工作有:(1)提出基于关联规刖的动态数据分发思想.(2)设计了描述仿真系统成且之间数据交互情况的发布订购树(PS-Tree).(3)基于PS-Tree挖掘关联规则,实现动态数据分发策略.(4)给出动态数据分发策略性能的量化分析。实验结果说明动态数据分发策略通过提高组播资源利用率,有效实现了基于值的数据过滤,减少了冗余数据的发送与接收,从而提高仿真系统的实时性、稳定性。
To ensure the efficiency of data exchange between simulation members via multicast groups in the simulation system based on HLA, the method of dynamic data distribution strategy was proposed based on association rule. The main contributions include: (1) Proposing the concept of dynamic data distribution strategy of HLA based on association rule. (2) Proposing the structure of Publishing & Subscription Tree(PS-Tree), which can manifest the relationship of data exchange between simulation members. (3) Giving the method to mine association rules of the publishing & subscription records set via PS-Tree and forming the forwarding table which realizes the strategy and (4) Analyzing the performance of dynamic data distribution strategy. Experiment shows that the strategy improves the efficiency of data exchange because of the more efficient use of multicast groups resource.
