Abstract: Many traditional security technologies such as intrusion prevention and intrusion detection are subject to restrictions in the network environment of mobile ad hoc networks can not achieve the desired results. This paper introduces mobile agents in wireless ad hoc network security model, designs a distributed intrusion detection and respond system. Through a variety of functions of mobile agent the system implements the functions of intrusion detection intrusion, and uses mobile agents to track, isolate invasion node to make a timely response. Experimental results show that this method can save the resources of node and avoid the collapse of the network, effective in detecting and preventing intrusions.

摘要： 传统网络中的入侵阻止和检测等防护方法在网络结构脆弱、节点移动的移动自组网络中无法达到预期效果。将移动代理引入无线自组网络中，设计分布式入侵检测响应系统，通过多种功能的移动代理实现入侵检测功能，并在入侵检测的基础上利用移动代理跟踪、隔离入侵节点，对入侵节点做出及时响应。实验结果表明此方法节省网络节点资源、避免网络的崩溃且达到主动响应隔离入侵节点的效果，有效地检测并阻止了入侵行为。
