Abstract

AIS is the most important navigation equipment for the identification of other ships, etc. However, the AIS overload problem has been raised recently due to an increase in AIS equipped vessels. The government is planning to introduce the wireless LTE network at 100 km offshore as part of the SMART-Navigation project. Continuous development and dissemination of the services available through such platforms will be necessary to achieve major goals such as marine accident prevention and environmental protection. In this study, we applied a WAVE communication system, which could be the basis for the development of such services. As a result, reliable data transmission was confirmed for a range of communication of approx. 5 miles, although the service was limited to 1 km in road traffic. Therefore, it is expected that WAVE communication technology will be used to prevent marine accidents through such efforts as collision avoidance and the transfer of marine safety information between ships.

AIS는 상대선박의 식별 및 정보 등의 전송을 담당하는 주요 항해통신설비이지만, 최근 AIS 활용도의 증가로 과부하 문제 등 문제점이 대두되고 있다. 정부는 SMART-Navigation 사업 추진의 일환으로 연안 100 km에 무선 LTE망을 도입하는 계획을 수립 중에 있고 해양사고예방 및 환경보호 등 주요 목표를 달성하기 위해서는 이러한 Platform 위에 이용 가능한 서비스의 지속적인 개발 보급이 필요할 것이다. 본 연구에서는 이러한 서비스 개발의 기반이 될 수 있는 차량용 무선통신기술(WAVE)을 해상에 적용하고자 실선 해상실험을 통해 WAVE 환경성능 평가를 실시하였다. 연구 수행 결과, 도로교통에서는 최대 1 km 내로 서비스가 제한되었지만 해상에서는 약 5마일 정도의 통신범위에서 신뢰성 높은 Data 전송이 가능한 것으로 도출되었다. 이러한 실험 결과에 따라 추가적인 연구를 통해 충돌 회피 및 선박간 해양안전정보 전송 등 해양사고 예방에 WAVE 통신기술이 다양하게 활용 될 것으로 기대된다.
