Abstract :
In this paper, we investigate the simulation time and wall clock time synchronization problem for High Level Architecture (HLA). We first identify and analyze two drawbacks in the traditional HLA-based time synchronization algorithm. A novel time synchronization algorithm based on synchronization events is then proposed to address these two drawbacks. To verify the proposed algorithm, experiment are conducted in the HLA based distributed and hardware-in-the-loop simulation systems. The experimental result shows that our approach significantly outperforms the traditional algorithms.
