Abstract

This paper analyzes the synchronization mechanism of distributed simulation model SDAG and obtains the sufficient conditions for events synchronization.Then MATW and GDSM algorithms have been proposed which can adjust the synchronization delay by predicting the runtime difference of simulation and the arriving time difference of input messages of all simulation entities.The test result has showed the good performance of the new algorithms in improving system synchronization.
