초록

센서 레지스트리 시스템은 이기종 센서 네트워크 환경에서 센서 데이터의 즉시적 활용 및 끊김 없는 해석을 위해 개발되었다. 그러나 기존 센서 레지스트리 시스템은 불안정한 네트워크 상황에서 센서 데이터 해석을 위한 정보를 제공하지 못하며, 이로 인해 센서 데이터의 손실, 처리 결과의 부정확성, 서비스 품질 저하 등의 문제를 야기한다. 이 논문에서는 소프트웨어 관점에서 이러한 문제점을 해결할 수 있는 방안을 제시한다. 사용자의 이동 경로를 예측하여 사전에 센서 정보를 이동 단말기에 제공함으로써 불완전한 네트워크 접속 시점에 안정적으로 센서 정보를 활용할 수 있는 확장된 센서 레지스트리 시스템을 제안하고 실험 및 평가 결과를 보인다. 이 논문에서 제안한 확장된 센서 레지스트리 시스템은 센서 정보의 안정적 활용성 증가와 더불어 센서 기반 서비스 품질을 향상시킨다.

The sensor registry system has been developed for instant use and seamless interpretation of sensor data in a heterogeneous sensor network environment. However, the existing sensor registry system cannot provide information for interpretation of the sensor data in situations in which the network is unstable. This limitation causes several problems such as sensor data loss, inaccuracy of processed results, and low service quality. A method to resolve such problems in the aspect of software is presented herein. In other words, an extended sensor registry system is proposed to enable the stable use of sensor information, even under conditions of unstable network connection, by providing sensor information with a mobile device in advance through the user path prediction. The results of experiments and evaluation are also presented. The extended sensor registry system proposed in this paper enhances the stable usability of sensor information as well as improves the quality of sensor-based services.
