Tactical Wireless Communications Network Interference Method Research

Tactical wireless communication network is the main part of digital land army tactical command system. Based on the analyzing of the composing and link relationship of tactical wireless network, a network model was brought forward.The features of tactical wireless network were studied, and the composing of tactical wireless network was analyzed. The service model and the producing of call stream and the calculating of route and the sorting of critical link were studied. The simulation model of tactical wireless network and the searching method of route and the principle of critical link sorting were provided.Based on the studying of tactical wireless network simulation theory, the simulation software running on Windows XP was written using Visual Basic 6.0. Used software programming to simulate the tactical wireless network, the validity of the jamming methods was confirmed and a reasonable conclusion was given. The result of simulation implied that the tactical wireless network is a weighted netwok and the jamming to its critical link can destroy its connection effectively.The critical link sorting and the network invulnerability and the embedded jamming method were simulated and studied using software. The needed suppress ratio of network node to affect the running of network critically was given. The result of simulation implied that the whole network communication ability can be declined dramatically when above 20 percent of its nodes were destroyed.
