摘要： 基于无线网络交叠信道邻频间干扰及802.11 DCF机制，在合理挑选干扰频道、尽量减少网卡跳变次数的基础上，设计并实现一种高效灵活的全频道干扰机。该干扰机配置有2个网卡，网卡a进行信道监测，网卡b根据网卡a返回的信道号差值数据，跳转到预置的干扰频道发送干扰信号，通过调节干扰信号发送速率实现不同的干扰概率。实验结果表明，该干扰机具有灵活、节能，可覆盖全13个频道的特点。

Abstract: Based on wireless network adjacent channel interference, 802.11 DCF model and reasonable interference channel to minimize the wireless card jump times, this paper designs a high efficient and flexible all-channel jammer. This jammer is equipped with two wireless cards. Card “a” monitors network, and card “b” jumps to the proper interference channel and sends radio signals according to the channel number difference from card “a”. Experimental results show that this jammer has the advantages of being flexibility, energy-saving and covering all 13 channels.

Key words: all-channel jammer, efficient interference, interference probability, adjacent channel interference, channel monitoring, network card jump
