A dynamic epoch time synchronisation method for distributed simulation federates is presented. The proposed approach allows federates to advance their local times at full speed to the global safe point, which is dynamically estimated using the look-ahead function for each federate. The simulation then slows for an interaction between federates. This approach aims to reduce the number of time synchronisation occurrences and duration of the conservative phase. The distributed simulation is implemented using the web services technology. The experimental results reveal that the proposed approach reduces simulation execution time significantly while maintaining complete accuracy as compared with two existing methods.
