Abstract

Marine data communications still look for a novel data communication system at sea because of the restriction of bandwidths and costs of current carriers. In order to make the most efficient use of the broadband land carriers at sea, this paper proposes a routing scheme (MCS-NTC) at a marine MANET model. The routing scheme optimizes the route by choosing optimal nodes and carriers among the traditional and land carriers based on normalized transmission characteristics of applications and carriers. The performance is compared with the max-win method (OMH-MW) scheme considering the specific values of transmission characteristics. The result shows that our scheme derives more efficient routes than the previous one in terms of the transmission characteristics such as bandwidth, cost, delay, the number of hops and carriers.

해상데이터통신은 아직 전송률과 비용의 제약으로 새로운 체계가 요청된다. 육상의 광대역접속기술들을 해상에서 최대한 활용하기 위하여 제안되는 자율망 모델에서 개별 링크별로 최적의 캐리어를 선택하여 전송성능을 최적화하는 경로배정방식을 제안한다. 이 방식은 각 링크별로 응용과 캐리어의 전송특성을 정규화된 값으로 최적 노드와 캐리어를 찾아 최적경로를 선택하는(MCS-NTC) 방식이다. 전송특성의 구체적인 값을 서로 비교하는 최다승방식(OMH-MW)과 성능을 비교하였다. 이를 통해 이 논문에서 제안하는 MCS-NTC 방식이 여러 전송특성(대역폭, 비용, 지연시간, 홉수, 캐리어수)과 경로탐색시간 측면에서 기존 방식에 비해 더 효율적인 경로를 형성함을 확인할 수 있었다.
