The Ministry of Maritime Affairs ＆ Fisheries have plaining the advancing fishery information integrated system for the fishing present condition, marine resource administration and applicability considering. The fishery information communication system is build up to the raw data ＆ process-network-content. The communication system must be small size, low cost and adapted SSB transceiver, that is using fishery shipping. In this paper We present digital data communication network to exchange information for fishery and safety between fishing ship and coast station in cheeper communication fee using SSB in HF band.

In recent years, many mobile wireless communication devices and applications have been deployed on the planet. The mobile multi-hop wireless network models appeared to provide means to access to networks where few infrastructure exists. However, the mobile multi-hop wireless networks have weaker points in attacks and intrusions than the wired and one-hop wireless networks. In this paper, the secure routing issues in most mobile multi-hop wireless network models are surveyed in depth. The state-of-the-art technologies and research activities are explained. Finally, the issues and technologies for the secure routing specific to a maritime network model are sufficiently discussed as conclusions.

KORDI(Korea Ocean Research & Development Institute) built a research vessel JANG-MOK with 40 G/T for a survey and observation of oceanographic environmental characteristics at coastal region in September 2005. This paper introduced the implementation for hardware and software of an integrated information network that loaded in JANG-MOK, and depicted the function of an integrated information network, such as an installation of ga-bit based network, RS232C serial & UDP network interface of instruments, a data logging software of measured data, Hawkeye II software for supporting the efficient survey works, and a real-time navigation viewer. In addition, we presents the another implementation method for an integrated information network of oceanographic research vessels.

The current maritime data communications mainly depend on radio and satellite which have restrictions on data rate and cost. That leads to needs of novel relatively-high-speed data communication systems at sea just like on land. This paper proposes a routing protocol (MWR) for newly designed model of ship-to-ship communication networks at sea. The MWR protocol finds out an optimal route by selecting an optimal network for each specific application from overlapped networks of available wireless media at sea.

우리나라에서 발생한 해양사고는 80%이상이 소형선박이며 이러한 소형선박들은 해상에서 안전을 위한 규정에 근거한 통신 설비를 구비하지 못하고 있는 실정이다. 이는 현재 이용하고 있는 해상안전 통신망의 체제가 1999년 이후 GMDSS체제로 바뀌게 되면서 소형선박의 해양사고는 더욱 두드러지고 있으며 IMO에서도 이를 위한 대책을 강구하고있다. 이렇게 된 까닭에는 여러 이유가 있을 수 있으나 대표적으로 소형선박의 운영자가 영세하기 때문에 고가의 통신장비의 도입이 어려운데 있다. 그리고 이미 이러한 소형선박들의 거의 대부분이 육상의 이동통신시스템을 이용하는 빈도가 늘고있으므로 이를 합리적으로 이용하기 위한 방편을 마련하는 것이 타당하다. 이 논문에서는 육상의 소형선박을 위한 해상조난 통신을 위한 통신망을 우리나라의 현실에 맞추어 설계 하고자 한다.

Those days, not only many peoples are killed and the wounded by effective of disaster sea wave in Indonesia, but also our country effected by disaster in adjoining sea to japan. At this point, preparation to disaster and the point of quickly communication by happened disaster. For this reason perceptible observation post are making so quickly communication system to zone by effective range of disaster, acd develope than more quality observation tool, contribute to keep citizens property acd life to a minimum by disaster damaged.

초고속해상무선통신망(LTE-maritime)은 '21년 1월 31일부터 해안으로부터 최대 100km 까지 해역을 집중관리구역과 관심구역으로 구분하여 통신서비스를 제공하고 있다. 현재 3톤 이상 선박을 LTE-Maritime 전용 송수신기 장착 의무 선박과 보조사업 대상 선박으로 지정하여 보급하고 있어 레저선박 제외한 전체 선박 중 약 55%에 해당하는 3톤 미만 소형선박을 위한 송수신기 개발 및 보급이 필요하다. 이에 따라 소형선박의 설치 환경을 고려한 소형화, 그에 따른 통신 가능 적정 거리 설정 등을 시험을 통해 고찰하고 향후 3톤 미만의 소형선을 위한 LTE-Maritime 송수신기 확대 보급 방안을 제안하였다.
