  • Many existent methods emphasize on constructing absolute consistency models, but without analyze the movement rules of virtual environment (VE), their practical values were limited. Beginning from the rules of VE, a realistic-based consistency model was proposed. Based on the human perception, a mathematical model for temporal and spatial consistency were built, which can be used in distributed virtual environment (DVE), to determine and verify whether nodes in VE were temporal and spatial consistent. By using one way data transmission, it reduced the number of rollback nodes after time distortion, and increased the sense of immersive; a time delay neural network was used to predict node status which was greater than the maximum propagation delay. Therefore, the temporal and spatial consistency is guaranteed by these strategies. The experimental results demonstrated the effectiveness of this method and a conclusion had been drawn.
