Abstract: Medium Access Control(MAC) protocol has a decisive influence on the overall performance of tactical data links, and how to evaluate the performance of MAC protocol is an important part of the life cycle of tactical data links.TDMA is the most widely used access method in tactical data links, so, the evaluation indexes of slot assignment protocol were proposed,and a simulation evaluation method of slot assignment protocol for tactical data links was proposed.Then, the simulation evaluation framework was designed, the simulation models and the process of the framework were discussed. Finally, the validity of the method was verified by a simulation evaluation example.

Key words: Tactical data link, Medium access control(MAC) , Slot assignment protocol, Simulation evaluation, Link 16
