With the expansion of distributed interactive simulation, the efficient dissemination and filtering of simulated information become important problems. Considering the fixed type of simulated data and the broad span of attribute number in distributed interactive simulation field, and based on the study and analysis of current event matching algorithm, a new structure of schema covering set (SCS) was proposed. A Simulated Data Matching algorithm based on the schema covering was then designed in this paper. By considering the relationship among predicates and the covering relation among subscriptions' schemas synthetically, the algorithm accelerates the matching performance by reducing redundant predicates matching and organizing subscriptions efficiently. Finally, experiments show that compared with counting method, the algorithm has considerable improvement in matching performance.
