For the application scenarios of the simulation of access strategy based on CRN,access strategy based on CRN is simulated by event scheduling and factually simulation of the behavior of the primary users and CR users is given in this paper.This simulation method takes the event as the basic unit,schedules the time of the event and executes each event in the order of time.This simulation method is also applicable to the simulation achievement of the multiusers chance shared multichannel communications access strategy with different priority.The simulation result shows that:as the error of the numeric calculation result is within 1%,between simulation and theoretical analysis,so the simulation method is feasible.
