A kind of media access control (MAC) protocol for data link based on dynamic priority polling mechanism is Proposed,Using OPNET,this article constructs the simulating model of a time division multiple access (TDMA) data link based on dynamic priority polling mechanism,describes modeling process,and provides and analyses simulated results of a TDMA data link’s capability from four aspects: common ground station’s login time,network throughput,channel using efficiency,and media access delay. Simulation results show that TDMA data link’s throughput with dynamic priority polling mechanism is high,and it has excellent network access efficiency and controllability.
