초록

임시망으로서 애드-혹 네트워크는 네트워크가 설치된 환경이나 구조에 의하여 많은 영향을 받는다. 본 논문에서는 센서 네트워크나 IoT(Internet of Things)와 같은 특수한 통신 환경에서 사용될 것으로 예상되는 격자구조 애드-혹 네트워크의 전송성능을 정보침해가 발생되는 측면에서 분석하고 대응 방안으로 모색하여 본다. 본 논문은 NS-2를 기반으로 한 컴퓨터 시뮬레이션을 사용하여 수행하였으며, 성능측정은 응용 서비스로 널리 사용되는 VoIP(Voice over Internet Protocol) 서비스를 대상으로 하였다. 성능 파라미터로는 MOS(Mean Opinion Score)와 호연결율을 사용하였다. 성능분석 결과 침해가 발생되는 애드-혹 네트워크에서 MOS의 경우 랜덤구조가 격자구조에 비하여 성능이 다소 높았고, 호연결율의 경우는 격자구조가 랜덤구조에 비하여 우수한 성능을 보였다.

As temporary network, ad-hoc network has been effected by structures and implemented environments of networks. In this paper, transmission performance of lattice structure ad-hoc network, which is expected to use in sensor network and IoT(Internet of Things), is analyzed in point of intrusions and countermeasure for intrusion is suggested. In this paper, computer simulation based on NS-2 is used for performance analysis, VoIP(Voice over Internet Protocol) as a widely used service is chosen for performance measure. MOS(Mean Opinion Score) and call connection rate is used as performance parameter. As results of performance analysis, it is shown that for MOS, random network is better then lattice network at intrusion environments, but for call connection rate, lattice network is better then random network.
