随着Internet网络的发展,恶意用户对一些大型的Internet站点进行毁灭性的攻击,于是在有线网络中出现了入侵检测相关技术的研究。无线Ad-Hoc网络可以在任意时间,任意地点访问IP网络,由于其具有开放性、拓扑结构动态改变及缺乏中心检测/管理点和中心的防御能力等特点,它更加容易受到毁灭性的攻击。可是有线网络的入侵检测技术在Ad-Hoc网中无法充分地发挥作用。给出了针对Ad-Hoc网络的冲突检测和响应结构。 With the development of Internet, malicious users destructive to some large-scale Internet sites, so in the wired network appeared intrusion detection technology research. Wireless Ad-Hoc networks can access IP networks anytime, anywhere, and are more susceptible to devastating attacks due to their openness, dynamic topology changes, and the lack of defensive capabilities of central detection / management points and hubs. However, the intrusion detection technology of the wired network can not fully play its role in the Ad-Hoc network. The structure of collision detection and response for Ad-Hoc networks is given.
