Abstract

A wireless ship area network is required to configure and control various sensors and electrical instruments embedded or boarded in a ship. In such environment, wireless communication protocol adopting relaying function is needed because direct link or communication between two nodes is hardly guaranteed due to spatial constraints in a ship. In this study, we introduce and analyze a WiMedia Distributed MAC (D-MAC) based approach considering throughput and energy constraint of wireless communication module. Performance evaluation results demonstrate that the relay-based wireless communication protocol improves reliability of wireless communication network in a ship.

선박 안의 각종 센서와 전기전자장비를 구성하고 원격제어를 수행하기 위해 선내 무선 네트워크의 구성이 필요하다. 선내에서는 공간적 제약으로 인해 직접 통신이 어려운 상황이 발생하기 쉬운 환경이므로 무선통신 모듈 간 원활한 연결을 위해 릴레이 기능을 포함하는 무선통신 프로토콜이 적합하다. 이 논문에서는 선내 무선통신 시스템의 데이터 전송률을 높이기 위한 릴레이 기반 선내 무선통신 프로토콜을 적용하여 성능 분석을 수행한다. 제안된 방식은 전송효율의 향상뿐만 아니라 릴레이 기능 수행을 위한 각 단말의 에너지 소모를 함께 고려하여 단말의 배터리 소모로 인한 통신단절을 최소화할 수 있도록 하였다. 성능 분석 결과 릴레이 기반 선내 무선통신을 통해 선내 무선 네트워크의 신뢰성이 향상됨을 확인하였다.
