Abstract�� Simulation grid is a networked simulation platform by combining modeling and simulation (M&S) technology and grid technology. Node selection is an important method to increase the performance of simulation execution in simulation grid. Based on the feature of resource heterogeneousness in simulation grid, a formula appraising criterion for node selection was proposed, a mathematic model for node selection was built on the appraising criterion, and finally a node selection algorithm was designed. Experiment result shows that the algorithm puts emphasis on selecting nodes with good computation capacity, communication performance among nodes is considered at the same time, and the situation where good communication performance overlaps poor communication performance is avoided in this algorithm. So the node selection method is able to achieve the purpose of raising simulation execution efficiency.
Keywords�� simulation grid   high level architecture (HLA)   node selection
