| Abstract: | Deterministic and Stochastic Petri Net(DSPN) is adopted in modeling and simulation of CAN communication process.By changing the system parameters,such as interval of information arrival,blocked rate,access busy and idle rate,while analyzing effects of those parameters to system performance parameters--throughput and collision rate,the real-time performance of CAN is effectively analyzed,and valuable theories and methods for practical applications are provided. |
