| Abstract: | Based on the distributed system, how to realize the clock synchronization among different processors in distributed traffic network is carried out in this paper by applying the newest achievements in parallel simulation area. The fixed-time scanning optimistic synchronization is put forward to insure the consistency among the event logical relationships. Finally a network with 9 nodes is simulated as an example by applying the algorithm mentioned above. The significance of distributed simulation is embodied enough through comparing the sequential benefits with the parallel benefits. |
