Abstract
본 논문에서는 범용 운영체제에서 제공하는 디바이스 투명성을 센서노드 운영체제에 적용한 센서 투명성 아키텍처를 제안하였다. 센서 투명성을 지원하기 위한 표준 API와 센서 디바이스 추상화를 설계하고 TinyOS 운영체제에서 구현하였다. 본 논문에서 제안한 센서 투명성 지원 센서노드 운영체제를 사용하면 응용 개발자는 운영체제에서 제공되는 표준 API를 통해 센서 디바이스에 독립적으로 응용 프로그램을 개발할 수 있고, 센서 디바이스 공급자 또한 표준화된 하드웨어 인터페이스와 HAL 인터페이스를 통해 센서노드 하드웨어 플랫폼에 독립적으로 센서 디바이스 드라이버를 개발하고 공급할 수 있다. In this paper, we proposed an architecture for supporting sensor transparency in sensor node operating systems, design the standard APIs (Application Programming Interfaces) and sensor device abstraction to provide the sensor transparency and implemented the sensor transparency in the TinyOS, the most well known sensor node operating system. With the proposed sensor node operating system which can support the sensor transparency, application developers can develop the target applications independent to each sensor device by using the standard APIs provided by the sensor node operating system and the sensor device manufacturers also can develop sensor device drivers by using the standard hardware interfaces and HAL (Hardware Adaptation Layer) interfaces independent to the specific hardware platform of sensor nodes.
