Abstract：Tactical Data Link (TDL) is a system that uses wireless network communication technology and protocols to realize information exchange among combat units, so as to maximize the effectiveness of tactical systems.The typical application of data communication technology in military field is first equipped with ground air defense system and naval ships, and then gradually applied to aircraft.This paper mainly studies LINK11 data link in tactical data link, and puts forward three improved modes on the basis of LINK11 data link.Traditional LINK11 adopts polling networking mode.Although the implementation of this model is simple, it has low flexibility and the opportunity of each node uploading messages is equal, but it can not be adjusted according to the special needs of the current situation.Therefore, based on the traditional polling networking model of LINK11, this paper proposes three improved models, one is priority-based networking improvement model, the other is statistical probability-based networking improvement model, and the other is dynamic networking improvement model based on the idea of ad hoc network.These three improved modes have improved the traditional network-building mode of LINK11 from different ideas and different perspectives, making it more suitable for some scenarios that LINK11 may encounter in practical application.The improved models have different effects and disadvantages. In this paper, the three models are simulated and compared with the simulation results of the traditional polling network model, and the conclusion is drawn that the future research direction is proposed.
