摘要
利用媒介访问控制层(Media Access Control,MAC)协议的知识对无线网络关键帧进行智能干扰,具有较高的干扰效率和较低的检测概率。定义了在智能干扰条件下无线网络信道的5种状态,建立了无线网络在受到智能干扰时的无线信道状态转换模型。根据这些状态的组合情况,提出了基于对状态转换模式进行统计的对智能干扰检测模型,并给出了对智能干扰概率进行估计的方法。通过NS2网络模拟的手段验证了模型的准确性。
By using of the knowledge about MAC protocol, a jammer can disrupt the key frame to achieve intelligent jamming, which has higher jamming efficiency and lower detection probability. Five states of the wireless channel under intelligent jamming are defined, and a state transition model is established ; based on the combination of various states, an intelligent jamming detection model is proposed, and the jamming probability is estimated ; validation of the model is performed by making use of NS2 network simulator.
