摘　　要：移动自组网(MANET)是由移动节点自组织形成的无线网络,由于其动态拓扑的特点,容易遭受各种安全威胁,而入侵检测技术能有效地保障移动自组网的安全.对已有的分级入侵检测技术进行分析,提出一种基于区域分级的入侵检测系统(IDS),避免了对节点的重复监控及尺寸小的簇的形成,减少了节点的运算负荷与通信负荷,提高了簇头的稳定性,避免簇头频繁选举带来更多的资源消耗.A mobile ad hoc network is a wireless network that is formed automatically by a collection of mobile nodes.It is particularly vulnerable due to its characteristics of dynamic changing topology.Intrusion detection technology can effectively protect mobile ad hoc networks from attack.In this paper,the existing hierarchical approach are analyzed and a zone-based hierarchical IDS is proposed.The new approach can prevent duplicate monitoring on nodes and small cluster fragments.Moreover,it can decrease the computional complexity and the bandwidth consumption,The stability of cluster heads is improved and resources consumption of cluster heads election is reduced.
