본 논문에서는 센서노드들을 관리 대상이 되는 지상시설물에 부착하여 다양한 사건 및 상황 감지 기능을 가지고 수집한 데이터를 특정 메시지 형식으로 정의하여 IP(Internet Protocol) 네트워크에 연결된 운용자 시스템에 전달하는 센싱 데이터 수집 및 전달 서비스 개발에 관한 사항들을 기술한다. 센싱 데이터 수집 및 전달 서비스는 게이트웨이 시스템에 설치되는 순수 소프트웨어이며, 센서네트워크의 싱크노드로 부터 센싱 데이터를 수집하여 XML 형식으로 구성되어 IP 네트워크에 연결된 운용자 시스템에 전달된다. 또한, 센싱 데이터 수집 및 전달 서비스는 운용자가 요구하는 센서네트워크 제어 서비스 컴포넌트, 센싱 데이터 수집에 관한 특성 변경 서비스 컴포넌트, 센싱 데이터 보고 서비스 컴포넌트, XML 파서/인코더, C-구조체 메시지 파서/인코더 컴포넌트 등의 추가 및 변경이 용이한 유연한 소프트웨어 구조를 갖도록 서비스 로직 개념을 도입하였다.
