Abstract

In this paper, End-to-End VoIP(Voice over Internet Protocol) performance over large scale MANET(Mobile Ad-hoc Networks) is evaluated. VoIP implementation model, which can be used for large scale MANET, is suggested through this evaluation. VoIP simulator based on NS-2 network simulator is used for performance measurement. Call connection ratio as a connection performance, MOS and network delay as a transmission performance, packet loss rate as other performance is measured with this simulation. Finally, maximum $10{\sim}15km^2$ as a single MANET, 500 nodes and 100 call connections is suggested for VoIP implementation and operation conditions over large scale MANETs.

본 논문에서는 대규모 MANET을 대상으로 VoIP 트래픽의 종단간 성능을 측정하고 분석하여 보았다. 측정된 결과의 분석을 통하여 대규모 MANET에서 사용 가능한 VoIP 구현조건을 제시하였다. 성능측정은 NS-2 네트워크 시뮬레이터를 기반으로 제작한 VoIP 시뮬레이터를 사용하였다. 시뮬레이션을 통하여 접속품질로서 호연결율, 전송품질로서 MOS, 네트워크지연, 그 이외의 평가척도로서 패킷손실율을 측정하였다. 본 논문의 결과로서 대규모 MANET에서 VoIP 구축과 운영에 적합한 조건이 단일 네트워크 규모로 최대 $10{\sim}15km^2$이내, 노드수 로 500여개, 호연결수로 100여개임을 확인하였다.
