无限传感器网络需要一种有效的、灵活的入侵检测方法来抵御入侵。根据无限传感器网络的特征,我们设计了一种基于移动Agent的动态入侵检测系统。该系统包括四种Agent,监控Agent、检测Agent、响应Agent和管理Agent。多个Agent分部合作,并采用异常检测算法进行检测,从而提高了无限传感器网络的安全性和可靠性,同时也降低了入侵检测时的能耗。
Wireless sensor network (WSN) requires an efficient, lightweight and flexible intrusion detection to defend attackers. According to the characteristics of wireless sensor networks, we proposed a dynamic intrusion detection system based on mobile agents. It contains four agents - monitor agent, detection agent, response agent, and management agent, which work together to accomplish detection by anomaly detection. It improves the security and reliability of wireless sensor networks, and lowers the power consumption of intrusion detection at the same time.
