Abstract

Since the underwater communication environment, which is used mainly in acoustic channel, is different from terestrial communication, it needs to analyze the appropriate transmission performance in underwater environment to implement the communication services. Appropriate traffic process method for a communication service is required through transmission performance of object traffic for the communication service. In this paper, transmission performance of video traffic on underwater MANET(Mobile Ad-hoc Network) is analyzed and video traffic configuration scheme on underwater MANET with results of performance analysis is suggested, This study is done with computer simulation based on NS(Network Simulator)-3. throughput, transmission delay, packet loss rate is used for transmission performance.

음향채널을 주로 사용하는 수중통신환경은 지상통신환경과 달라 통신 서비스를 구축함에 있어 수중환경에 적합하게 전송성능을 분석하는 것이 필요하며, 통신망의 일반적 성능 뿐 아니라 통신 서비스별 전송 대상 트래픽의 전송성능을 분석하여 통신서비스에 적절한 트래픽처리 방안의 강구가 요구된다. 본 연구에서는 수중 MANET(Mobile Ad-hoc Network)에서 비디오 트래픽의 전송 성능을 분석하고 이 결과를 토대로 비디오 트래픽 전송 방안을 제시한다. 본 연구는 NS(Network Simulator)-3에 기반한 컴퓨터 시뮬레이션을 이용하여 수행하며, 전송 성능으로는 처리율, 전송지연, 패킷손실율을 사용한다.
