摘　　要：通过干扰源与网络双方的交互行为进行建模并结合输出结果,在干扰源能耗受限的假设条件下,给出了理性干扰攻击下的无线网络最优传输控制策略.为了提高网络抗干扰性能,本文还提出了一种通过控制博弈输出结果减轻干扰影响的方法.分析结果表明,本文所提方法对网络影响较小的情况下达到减轻干扰影响的目的.In this paper, the mutual interaction between the network and the jammer was modeled under the fact that the jammer is always energy constrained, and then the optimal transmit policy was presented. To improve the performance of the network in avoidance of the interference of the malicious side, the algorithm based on the argumen- ted game theory for draining the jammer^s energy was proposed. Numerical results show that the energy cost of jam- mer is effectively increased and its influence on the network is minimized. Therefore, the performance of network un- der jamming is improved.
