초록

사물인터넷(Internet of Things, IoT) 패러다임이 대두되며 센서의 개체수가 폭발적으로 증가할 것으로 예상됨에 따라 센서 네트워크 및 센서 플랫폼 기술들이 변화되고 있다. 센서 플랫폼 중 하나인 센서 레지스트리 시스템(Sensor Registry System, SRS)은 이기종 센서 네트워크 환경에서 센서 데이터의 일관성 있는 의미 해석을 위하여 센서 메타데이터를 등록하고 관리하는 시스템이다. 하지만 기존의 SRS는 IoT 환경에 적합한 데이터 구조를 지니고 있지 않다. 따라서 이 논문은 IoT 환경에서 센서 정보들을 관리하고 등록하기 위하여 센서 레지스트리 데이터 모델을 제안한다. 기존의 SRS를 개선하기 위하여 시맨틱 센서 네트워크 온톨로지(Semantic Sensor Network Ontology, SSNO)을 분석하고, 이에 기반한 메타모델을 설계한다. 또한 설계한 메타모델을 이용하여 관계형 데이터베이스의 테이블로 구축하고 SRS를 웹 애플리케이션으로 구현한다. 이 논문은 제안하는 센서 레지스트리 데이터 모델의 적합성을 검증하기 위하여 SSNO 및 센서 온톨로지 예제들을 변환하여 제안 모델에 적용한다. 평가 결과 제안 모델이 기존 연구들보다 더 풍부한 의미 표현이 가능함을 보인다.

With emerging the Internet of Things (IoT) paradigm, the sensor network and sensor platform technologies have been changed according to exploding amount of sensors. Sensor Registry System (SRS) as a sensor platform is a system that registers and manages sensor metadata for consistent semantic interpretation in heterogeneous sensor networks. However, the SRS is unsuitable for the IoT environment. Therefore, this paper proposes sensor registry data model to register and manager sensor information in the IoT environment. We analyze Semantic Sensor Network Ontology (SSNO) for improving the existed SRS, and design metamodel based on the analysis result. We also build tables in a relational database using the designed metamodel, then implement SRS as a web application. This paper applies the SSNO and sensor ontology examples with translating into the proposed model in order to verify the suitability of the proposed sensor registry data model. As the evaluation result, the proposed model shows abundant expression of semantics by comparison with existed models.
