移动/便携设备大多支持无线接口,主要通过无线介质进行通信。无线通信是很容易受到干扰的,因此他们很容易受到干扰攻击,包括非常受欢迎的基于IEEE 802.11的无线局域网络(WLAN)。检测干扰攻击通常是开发一种抗干扰对策的第一步。该论文主要描述了存在干扰机的标准WLAN站的数学模型到行为模型。各站的MAC协议采用马尔可夫链建模,并导出流量表达式,通过建立在实验室的干扰机进行干扰测试实验,理论和实验结果进行了比较,验证了马尔可夫模型是准确的。为进一步提出抗干扰激励方案、抗干扰对策研究提供了可借鉴的技术方法。
Most mobile / portable devices support wireless interfaces and communicate primarily through wireless media. Wireless communication is very susceptible to interference, so they are vulnerable to interference attacks, including the very popular IEEE 802.11-based wireless local area network (WLAN). Detecting Interference Attacks are usually the first step in developing an anti-interference countermeasure. This paper mainly describes the mathematical model to behavior model of a standard WLAN station with jammer. The MAC protocol of each station uses Markov chain modeling and derives the traffic expression. The disturbance experiment is carried out by a jammer in the laboratory. The comparison between the theoretical and experimental results shows that the Markov model is accurate. In order to further propose anti-jamming incentive scheme and anti-jamming countermeasure research, it provides a technical method that can be used for reference.
