초록
본 논문에서는 해상에서 수집되는 다양한 출처의 정보들을 수집할 수 있는 빅데이터 플랫폼을제안한다. 현재 운영되는 해양 관련 빅데이터 플랫폼들은 만들어진 데이터를 저장 및 공유하는데초점이 맞추어져 있고 데이터 수집과 전처리는 데이터 제공자가 각자 담당한다. 지상 대비 열악한 통신망을 사용하는 해양 환경에서 데이터를 수집 및 통합하는 것은 높은 비용과 비효율성이존재하며, 이로 인해 관련 인프라의 구현이 쉽지 않다. 특히 기상 정보, 레이더 및 센서 데이터등 실시간 데이터 수집 및 분석이 필요한 분야의 경우 통신망 문제와 더불어 데이터 보안, 조직과 선박의 특성, 데이터 수집 비용 문제 등 지상 대비 다수의 문제를 고려해야 한다. 먼저 본 논문에서는 이 문제들을 정의하고 해결방안을 제시한다. 그리고 이를 반영한 빅데이터 플랫폼 설계를 위해 데이터 소스, 계층적 MEC, 데이터 전송 구조를 우선 제안한 후 이를 모두 통합한 전체플랫폼 구조를 제시한다.
Abstract
In this paper, we propose a big data platform that can collect information from various sources collected at ocean. Currently operating ocean-related big data platforms are focused on storing and sharing created data, and each data provider is responsible for data collection and preprocessing. There are high costs and inefficiencies in collecting and integrating data in a marine environment using communication networks that are poor compared to those on land, making it difficult to implement related infrastructure. In particular, in fields that require real-time data collection and analysis, such as weather information, radar and sensor data, a number of issues must be considered compared to land-based systems, such as data security, characteristics of organizations and ships, and data collection costs, in addition to communication network issues. First, this paper defines these problems and presents solutions. In order to design a big data platform that reflects this, we first propose a data source, hierarchical MEC, and data flow structure, and then present an overall platform structure that integrates them all.
