Simulation and analysis of polling multiple access system for tactical data link by Matlab Stateflow modeling

By utilizing the MATLAB Stateflow tool, which is developed by finite-state machine theory, this paper constructed a tactical data link networks model. The model adopted the gated polling scheme with priority control service under the condition of 3, 5 and 10 stations involved in the networks respectively. The station with higher priority can be prior served through interrupting other station's information transmitting. From the simulation experiments, the delay characteristics of the stations and networks under various transfer rate have be shown and analyzed, especially for Link 11 system. As a result, it is concluded that the polling mechanism and modeling method proposed by authors are effective for the tactical data link modeling and analysis.
