Research on Tactical Internet Real-Time Simulation for Training

Simulative training should include network simulation in information age, and network simulation needs to meet the real-time requirements. For the real-time implementation of Tactical Internet (TI) simulation, the paper proposed a "water-wave type" topology updating method for simulation, which solved the real-time problem of tactical radio network topology updating simulation. Secondly, the paper proposed a data packet transmission method based on characteristic information, which solved the large data problem of TI simulation, and then the real-time of simulation was improved. Finally, the paper proposed a transmission success-rate calculating method based on prediction, which solved the real-time simulation problem of transmission. The practical application proved that the paper’s methods had good effect.

Research on Appraising of Tactical Internet Simulative Training

Appraising is an important work of Tactical Internet (TI) simulative training. As a new type of network, the appraising of TI training needs to be solved by new method. Therefore, the paper set up a new index system firstly, laid the foundation for the appraising of Tactical Internet simulative training. Secondly, the paper used a Petri net method, which solved the acquisition problem for those indexes that are dynamic changed and not easy to be directly calculated. Thirdly, the paper used a BP neural network method, which solved the calculation of index weights. Finally, based on the method of satisfaction degree, the paper set up an appraising model which realized the appraising of trainees’ training level。The paper’s work has been applied in practice and achieved good results.
