Abstract

An integrated ship area network has functionality of remote control and autonomous management of various sensors and instruments embedded or boarded in a ship. For such environment, a wireless bridge is essential to transmit control and/or managing information to sensors or instruments from a central integrated ship area network station. In this paper, one of reliable schemes of wireless bridge using WiMedia distributed MAC (D-MAC) protocol is proposed to increase a communication reliability. Simulation results show that the proposed wireless bridge using WiMedia D-MAC protocol guarantees reliable communications between 2-hop devices.

선내 통합유무선 네트워크에서는 선내의 각종 센서와 제어기를 자율적으로 구성관리하고 원격제어를 제공하는 기능을 수행한다. 특히 센서장비에 장착되는 무선통신 모듈은 선내 통합유무선 네트워크와의 원활한 연결을 위하여 무선 게이트웨이 기능을 수행하는 브릿지(bridge)를 통한 데이터 전송방식이 필요하다. 본 논문에서는 이러한 선내 통합유무선 네트워크를 위한 무선 브릿지로 와이미디어기반 통신방식구조를 제안한다. 제안한 무선 브릿지구조에서 선내 제어 유선네트워크의 정보를 효과적으로 전송할 수 있는 방안으로 분산적인 MAC 기반의 와이미디어 통신 방안을 적용하여 성능을 분석한다. 제안한 방식을 시뮬레이션한 결과, 선내 디바이스의 2홉 이동성에서는 신뢰성 있는 통신 성능이 보장됨을 나타내었다.
