Abstract

A gateway buoy system connects a underwater network to a terrestrial network, which enables to efficiently monitor the underwater network on a land station. In this paper, we introduce an implemented gateway buoy system which relays gathered data from multiple underwater nodes to a land station in a real time. The gateway buoy hardware system is composed of a underwater acoustic modem system, a radio frequency modem system, and a gateway operating system. in additional, we have implemented a land operating program and a land monitoring program for gateway system and states of underwater network, respectively. We also perform real-sea experiments to verify the performance of the gateway buoy system which real-time monitors underwater network states and gateway system states.

게이트웨이 부이시스템은 수중 어플리케이션 구현 시 수중-육상 간 네트워크 연계를 위한 시스템으로 수중노드와 육상국간 통신 연계, 수중 네트워크 모니터링 등을 수행한다. 본 논문에서는 다수의 수중노드로 수중 네트워크를 구현 시 취득된 데이터들을 육상국과 연계하여 실시간으로 모니터링이 가능한 게이트웨이 부이시스템 개발에 대해 소개한다. 개발된 게이트웨이 부이시스템은 수중음향통신모뎀, RF 통신시스템, 게이트웨이 운용시스템으로 구성되며, 게이트웨이 운용과 수중 네트워크 상태모니터링을 위한 육상국용 관제 프로그램을 구현하였다. 또한 실 해역 시험을 통해 실시간 수중 네트워크 모니터링, 게이트웨이 상태모니터링 등의 성능 검증을 수행하였다.
