Region Matching Algorithm Based on Historical Information Sorting in DDM
The key point of DDM implementation is to match the update region sets with the subscription region sets. The efficiency and performance of the distributed simulation system is determined by the design of matching algorithm. The matching algorithm must maintain the index form and the information form of region intersection. And the problem is that the forms are constantly extended. Firstly,the idea and realization of region aggregation were provided. Secondly, historical information sorting was added to the region matching algorithm. Therefore, the running efficiency of region matching was improved on the base of using historical information. The basic idea and detail process of the algorithm were provided in the paper. The implementation process of algorithm was amply explained by the application example. Finally, the advantage and disadvantage of the algorithm were analyzed by the simulation data.
