임의의 공간에 쉽게 설치하여 활용할 수 있는 센서 기술이 발달함에 따라 ITS (Intelligent Transport System) 분야에서도 여러 형태의 센서를 활용하여 차량을 검지하기 위한 연구가 진행되고 있다. 그러한 센서의 대표적인 예는 차량의 이동에 의해 발생되는 지구 자기장의 변화를 파악하여 차량을 검지하는 자기 센서라 할 수 있다. 본 논문에서는 차량 검지를 위해 구축되는 자기 센서 기반 무선 센서 네트워크 시스템에서 정의될 수 있는 응용 서비스 프로토콜을 제안 및 설계 한다. 이러한 응용 서비스 프로토콜에 포함되는 정보들은 크게 차량 검지 정보의 전달, 자기 센서 및 센서 네트워크의 상태정보 전달 및 이들에 대한 관리와 관련된 정보들로써 나뉘어 질 수 있다. 본 논문에서 설명되는 자기 센서 네트워크의 응용 프로토콜은 차량 검지 시스템에 구현되어 실제 테스트베드에 적용되었다.
