Ad Hoc网络中的入侵检测

随着Ad Hoc网络研究的深入,安全问题已引起广泛的关注。Ad Hoc网络由于其传输媒介开放、网络拓扑变化快、带宽资源有限、节点间仅靠合作而缺乏集中监控点等特性,容易遭受攻击。然而有线网络中的大部分入侵检测技术在Ad Hoc网络中并不适用,目前已有新的体系及算法提出,以适应新的环境。本文分析比较了已有的入侵检测技术,并指出了一些待解决的问题,作为未来研究工作的基础。

Intrusion Detection in Wireless Ad Hoc Network

Security of the Ad Hoe network is becoming more concerned as the research of this field carry on.Ad Hoc network is generally more vulnerable to threats due to its features of open medium,dynamic network topology,limited bandwidth and resources,cooperation algorithms,and lack of centralized monitoring point.But most techniques devel- oped in the wired network are not applicable in Ad Hoc network,new models and algorithms have been proposed in this new environment.In this paper we analyze and compare the existing intrusion detection techniques and also address the research trends in this area.
