Abstract

Data communications networks at sea in the future can be modelled by overlapped MANET networks with Broadband Wireless Access carriers. A novel routing scheme (CPLR) is proposed in this paper, which finds out an optimal route by selecting an optimal carrier for each hop in routes based on carrier preferences of each application, and locations of ships as well. As distances between each ships and destination ships are considered in this scheme, routing can be done much faster. Performance is compared with that of the CPR (only Carrier Preference-based Routing Scheme), and it shows some improvements.

미래 해상데이터통신망은 광대역무선접속(BWA) 캐리어들이 중첩된 자율망(MANET)으로 모델링될 수 있다. 이러한 망 모델에서 응용 서비스별 캐리어 선호도와 선박의 위치를 함께 이용하고 경로의 홉단위 최적 캐리어를 선택하여 최적경로를 찾는 라우팅방식(CPLR)을 새롭게 제안한다. 이 방식에서는 경로의 각 선박과 목적지 선박간 거리를 고려하기 때문에 최적경로를 찾아가는 수렴성이 개선되어 라우팅 시간을 더 줄였다. 캐리어 선호도만을 고려하여 최적경로를 탐색하는 (CPR)방식과 성능을 비교하여 개선결과를 보였다.
