分级的Ad Hoc网络入侵检测系统改进

随着无线网络的快速发展和移动计算应用的快速增加,移动无线网络安全问题愈加突出.入侵检测作为保证网络安全的一种有效手段已经从保护固定有线网络扩展到移动无线网络.作为无线移动网络众多实现方式之一的移动Ad Hoc网络分为平面和分级两种结构.由于其与有线网络存在很大差别,现有针对有线网络开发的入侵检测系统很难适用于移动Ad Hoc网络.本文在描述入侵检测相关技术的基础上改进了分级的AdHoc网络入侵检测系统体系结构,并给出了该系统的分簇算法,使之更好地应用于分级的Ad Hoc网络.

Improvement of Hierarchical Wireless Ad Hoc Network Intrusion Detection System

With the rapid increasing of wireless network and mobile computing,the safety of wireless networks becomes more important. As an effective method of protecting networks' safety,the application of Intrusion detection has extended from fixed wired networks to wireless mobile networks. Wireless mobile networks have plane or hierarchical structure. Due to the different network characteristics and transmission media,intrusion detection techniques used in wired networks are not well applied in mobile ad hoc networks. The paper describes intrusion detection techniques,improve the hierarchical wireless ad hoc network intrusion detection system and advance a new algorithm for dividing clusters in details,applying to hierarchical wireless ad hoc network better.
