초록

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 센서네트워크를 위한 그리드 기반 WPAN을 제안한다. 제안한 그리드 기반 WPAN은 그리드 기반의 네트워크 구조로서 다중 경로 통신을 지원하고 에너지 효율적이며 강인성을 갖는다. 제안한 방식을 시뮬레이션한 결과, 제안한 그리드 기반 WPAN은 IEEE 802.15.4 기반 망 보다 수율 및 전력소비 면에서 우수한 성능을 나타내었다.

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 In-ship sensor networks using a Grid-based WPAN is proposed. The proposed scheme is based on a novel grid network which allows a multi-path communication, and is robust, energy efficient. The results demonstrate that the proposed Grid-based WPAN outperforms the IEEE 802.15.4 based network in terms of success ratio and power efficiency.
