초록

최근 저성능 컴퓨팅을 통해 적은 양의 정보를 사용하는 소규모 사물 인터넷 서비스들이 확산되고 있다. 이를 위해 통신 반경이 넓고 전력 소모가 상대적으로 낮으며, 가격이 저렴한 저전력 장거리 통신 기술이 필요하다. 본 논문은 LoRa 통신 방식을 기반으로 넓은 지역에 분포되어 소량의 센싱 데이터를 전달하는 소물 인터넷 환경에서 멀티 홉 전송을 지원하는 MAC 계층과 라우팅 프로토콜을 제안한다. 단말 노드는 이동 가능하며, 통신 형태는 단말 노드와 네트워크 응용 서버 간의 양방향 전송을 제공한다. 제안한 프로토콜을 적용하여 스마트 팩토리 생산 설비 모니터링 시스템을 구축하였으며, 기본적인 모니터링 기능은 정상적으로 수행됨을 확인하였다.

Recently, small-scale IoT services using a small amount of information through low-performance computing have been spread. It requires low cost, low-power, and long-distance communication technologies with wide communication radius, relatively low power consumption. This paper proposes a MAC layer and routing protocol that supports multi-hop transmission in small-scale IoT environment distributed over a large area based on LoRa communication and delivering a small amount of sensing data. The terminal node is mobile and the communication type provides bidirectional transmission between the terminal node and the network application server. By applying the proposed protocol, a production line monitoring system for smart factory was implemented. It was confirmed that the basic monitoring functions are normally performed.
