Abstract

A wireless bridge is essential to transmit control and managing information to sensors or instruments from a central integrated ship area network station. In this paper, a WPAN protocol is adopted for development of a seamless N-screen wireless service in Indoor and Ship Area Networks. Furthermore, to provide the OSMU (One Source Multi Use) N-screen service through P2P streaming in the seamless WPAN protocol, a Grid-based WPAN networking technology is proposed and analyzed. The proposed Grid-based WPAN networking technology supports multi-path and fast path-setup functions for N-screen communications. The simulation results demonstrate that the proposed Grid-based WPAN networking technology outperforms the IEEE 802.15.4 based network in terms of N-screen transmission delay.

센서장비에 장착되는 무선통신 모듈은 선내 통합유무선 네트워크와의 원활한 연결을 위하여 무선 게이트웨이 기능을 수행하는 브릿지(bridge)를 통한 데이터 전송방식이 필요하다. 본 논문에서는 선박 및 실내 Seamless N-스크린 서비스를 위한 무선 통신 MAC 구조로서, WPAN 프로토콜을 적용하고, P2P 스트리밍이 가능한 OSMU(One Source Multi Use) N-스크린 서비스를 제공하기 위해, 그리드 기반 WPAN 네트워킹 기술을 제안하고 성능을 분석하였다. 제안한 그리드 기반 WPAN 네트워킹 기술은 다중 경로 및 신속한 경로 설정이 가능한 N-스크린 통신을 지원한다. 제안한 방식을 시뮬레이션한 결과, 그리드 기반 WPAN 네트워킹 기술은 IEEE 802.15.4 기반망 보다 전송지연시간 측면에서 우수한 성능을 나타내었다.
