초록

라우팅 정보에 대하여 악성침해를 일으켜 네트워크의 전송성능을 저하시키는 블랙홀 공격에 대한 대응수단으로 IDS(Intrusion Detection System)가 사용되고 있다. 본 논문에서는 IDS가 전송성능에 미치는 영향을 MANET(Mobile Ad-hoc Network)에서 노드의 이동패턴에 기반하여 분석하고, 블랙홀 공격에 대한 효과적인 대응방안을 살펴본다. 성능분석에는 NS-2를 기반으로 한 컴퓨터 시뮬레이션을 사용하며, 응용 서비스로 사용되는 VoIP(Voice over Internet Protocol) 서비스를 대상으로 성능을 측정한다. MOS(Mean Opinion Score)와 호연결율, 종단간 지연을 성능측정 및 분석 파라미터로 사용한다.

IDS(Intrusion Detection System) can be used as a countermeasure for blackhole attacks which cause degrade of transmission performance by causing of malicious intrusion to routing function of networks. In this paper, effects of IDS for transmission performance based on mobility patterns is analyzed for MANET(Mobile Ad-hoc Networks), a suggestion for effective countermeasure is considered. Computer simulation based on NS-2 is used in performance analysis, VoIP(Voice over Internet Protocol) as an application service is chosen for performance measure. MOS(Mean Opinion Score), call connection ratio and end-to-end delay is used as performance parameter.
