Abstract

Performance analysis results are limited to of network level, because network level transmission parameters are used for performance measure and analysis of network design, construction and operation on underwater MANET, With this way of performance analysis based on network level, it is not easy to analyze transmission performance related with user level transmission quality. In this paper, transmission performance focused on application traffic be required by user is investigated to supplement weakness of performance analysis based on network level. Voice traffic, which is expected to be increasingly used on underwater MANET, is considered as application service, Some conditions for underwater MANET will be proposed to support transmission quality, MOS, CCR and EED, etc.. A computer simulation based on NS-2 is used for performance measure, voice traffic is generated as VoIP specification.

수중 MANET의 설계, 구축 및 운용에서 전송성능의 측정 및 분석은 네트워크 차원의 전송 파라미터를 중심으로 수행됨에 따라 성능 분석 결과가 네트워크 수준의 성능에 국한되고 있어 사용자 수준의 전송품질과 관련한 전송성능을 분석 고찰하기에는 미흡한 점이 있다. 본 논문에서는 수중 MANET에서 네트워크 수준의 전송성능 분석의 단점을 보완하고자 사용자 수준에서 요구되는 응용트래픽 관점에서 전송성능을 분석한다. 수중 MANET에서 활용도가 증가할 것으로 예상되는 음성트래픽을 대상으로 전송성능을 분석하고, MOS, CCR 및 EED 등의 음성 전송품질 요구조건에 적합한 수중 MANET 조건을 제시한다. 본 연구는 NS-2를 기반으로 구축된 컴퓨터 시뮬레이션을 사용하여 수행하며, 음성 트래픽으로는 VoIP 규격을 사용한다.
