초록

연구목적: 본 논문에서는 상설 네트워크가 없는 장소에 Internet of things (IoT) 기기를 활용하여 이를 부착하는 것만으로도 실내 위치를 추적할 수 있는 측위기법을 제안한다. 연구방법: 본 논문의 제안기법은 단순한 계산을 통해 대상의 위치를 추정할 수 있는 weighted centroid localization을 활용한다. 연구결과: 일반 건물의 상설 네트워크가 없는 지하 주차장에서 제안하는 기법을 활용하여 실험을 진행하였고, 실험한 결과로 $82.5m{\times}56.4m$ 지하 공간에서 약 10m 이내의 위치 정확도를 확인하였다. 결론: 본 논문의 제안기법은 주차장, 창고, 공장 등과 같이 상설 네트워크 인프라가 없는 장소에서도 재난, 응급, 군사 작전 등과 같이 신속한 위치 추적을 필요로 하는 상황에 적용 가능하다.

Purpose: This paper propose a temporary indoor positioning scheme with devices of internet of things (IoT) for disastrous situations in places without the infrastructure of networks. Method: The proposed scheme is based on the weighted centroid localization scheme that can estimate the position of a target with simple computation. Results: It also is implemented with the IoT devices at the underground parking lot, where the network is not installed, of general office building. According to the experiment results, the positioning error was around 10m without a priori calibration process at $82.5m{\times}56.4m$ underground space. Conclusion: The proposed scheme can be deployed many places without the infrastructure of networks, such as parking lots, warehouses, factory, etc.
