摘　　要：充分利用协议的信息,如控制包的大小、内容、包间间隔等制定干扰策略,有可能实现对网络的智能干扰。IEEE802.11MAC协议是基于竞争模式的链路层协议,广泛应用于Ad Hoc等无线网络。利用该协议的信息进行干扰,可以使得攻击能够更精细,提高了干扰效率并降低被检测概率。讨论了根据MAC协议的信息对Ad Hoc网络进行智能阻塞攻击和欺骗干扰的单节点工作方式和多节点协同工作方式,比较了不同方式能够达到的干扰效果。Intelligent jamming of network may be achieved through jamming policy made by utilizing the protocol information about the size and contents of the control pocket as well as the interval between packets. IEEE802.11 MAC protocol is the link layer protocol based on competition, and is widely used in Ad Hoc network. Making use of the protocol information may lead to a refined attack, obtaining jamming efficiency and lower detection probability. Operation modes of intelligent blocking jamming and deceptive jamming of single node and multiple nodes are discussed, the effect of different methods are compared.
