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.
