Abstract

There are lots of studies on application systems using wireless sensor networks. As the application systems are adapted to industrial field, the reliability of these systems becomes new key feature. The lack of reliability is an obstacle to extension of wireless sensor networks. In this paper, we propose the monitoring system framework that can offer the reliability of wireless sensor networks using a micro camera module and wireless sensor network nodes. And also we propose the efficient transfer method for image information over low rate wireless networks. Using these system framework and transfer method, we implement WiSN(Wireless image Sensor Network) based fire monitoring system.

무선 센서네트워크를 이용한 많은 응용 시스템이 연구되고 있는 가운데 무선 센서네트워크 시스템의 신뢰성 확보에 대한 문제점이 대두되고 있다. 이러한 문제점은 센서네트워크의 활용범위를 확장하는데 장애 요인으로 작용하고 있다. 본 연구에서는 초소형 카메라 모듈과 무선 센서네트워크 노드를 이용하여 무선 센서네트워크의 신뢰성 확보를 위한 시스템과 저속의 무선 센서네트워크 상에서 효율적으로 영상정보를 전송하는 방법을 제안하였다. 또한 이러한 기술을 이용하여 무선 이미지 센서네트워크 기반 화재 감시 모니터링 시스템을 구현하였다.
