摘　　要：本文研究了针对WLAN的拒绝服务攻击,总结了当前危害最为严重的几种攻击方式,分别为假冒合法MAC地址的攻击和向无线接入点AP发送大的延迟包的攻击。这几种攻击实现容易,防范困难,研究其攻击机制和防御方法具有重大的现实意义。文章还利用OPNET仿真软件对攻击手段和攻击效果进行了仿真。最后,根据攻击原理提出了自己的防御方法。This paper study the denial-of-service attacks to WLAN, and summed up the current several ways of the most serious attacks, that were camouflage MAC address attack and sent a long packet delay to the AP the attack. These attacks were easy to achieve and difficulty to prevent, Research to these attacks on their defense mechanisms and methods is of great practical signifi- cance. The article also uses OPNET simulation software Simulates the attacks and analysis the effect of the simulation. Finally,the authors statement some defense methods.
