모바일 Ad-hoc 네트워크에서 효율적인 멀티캐스트 서비스를 지원하기 위한 메쉬구조

국문 초록 (Abstract)

본 논문에서는 모바일 Ad-hoc 네트워크에서 효율적인 멀티캐스트 서비스를 지원하기 위한 메쉬구조를 제안한다. 제안된 메쉬구조를 위한 두 개의 전략, 포워딩 노드들을 위한 어답티브 업그레이딩 및 포워딩 노드들을 위한 어답티브 다운그레이딩, 이 소개된다. 제안된 메쉬구조는 모바일 Ad-hoc 네트워크에서 노드들의 이동성과 데이터 전송률이 높을 때 심각한 혼잡문제를 해결할 수 있을 뿐만 아니라, 낮은 중복데이터를 가지고 높은 페킷 전송률을 지원할 수 있는 멀티캐스트 서비스를 지원할 수 있다. 본 논문의 성능평가는 OPNET을 사용한 시뮬레이션을 통해서 이루어진다.

다국어 초록 (Multilingual Abstract)

In this paper, we propose an evenly distributed mesh scheme to support services in mobile ad-hoc networks. Two strategies, the adaptive upgrading of forwarding nodes and the adaptive downgrading of forwarding nodes. are presented in the scheme. Our proposed scheme can support construction of better multicast mesh that can give higher packet delivery ratio with lower duplicate data as well as solve the problem of serious congestion especially when node mobility and data transmission rate are high in mobile ad-hoc networks. The performance evaluation is performed via simulation using OPNET.
