An information filtering method for Link16 system based on fresh-keeping degree

In view of the characteristic of TDMA slot resource allocation in Link16 system used by U.S. military and the application characteristics of battlefield situation information, the concept of information fresh-keeping degree has been proposed, and the delay performance of information transmission based on uniform flow, Poisson flow and burst flow under different time slot allocation is analyzed. Based on OPNET network simulation software, the simulation scenario of Link16 communication network based on planning is designed and constructed, and the correctness of the analysis results is verified. On this basis, a battlefield information filtering mechanism based on fresh-keeping degree is proposed. The theoretical analysis and simulation results show that the mechanism can effectively guarantee the effectiveness of receiving data under the strong service load scenario.
