Dynamic evaluation algorithm for anti-jamming effectiveness of wireless communication equipment based on game theory

The anti-jamming (AJ) effectiveness of the wireless communication equipment is influenced by the jammer and defender, it is necessary to consider the interaction of both sides respectively. To solve the problem of AJ effectiveness evaluation for the wireless communication equipment under different electromagnetic interference, a dynamic evaluation algorithm based game theory is proposed in this paper. Firstly, the evaluation index system is established according to the tactical strategies the equipment taken. Secondly, two kinds of index standardization methods, a combined weight setting method and a payoff calculation method under different strategies are designed to ensure scientific and reasonable evaluation process. Finally, the AJ effectiveness is evaluated by analyzing Nash equilibrium (NE) in the proposed game model. The simulation results show that it is an effective method to evaluate AJ effectiveness exactly due to take the strategies of both sides into consideration, which is more suitable and accurate for the effectiveness evaluation and analysis in the complicated electromagnetic environment.
