Abstract

Recently, indoor location detection has become an important area in the IoT (Internet of Things) environment for various indoor location-based services. In this paper, our proposed method shows that a virtual region can be divided electromagnetically according to specific facilities or services in various IoT application areas called zones. The MLP (Multi-Layer Perceptron) method is applied to recognize the service zone at the current position. The MLP utilized an RSSI (Received Signal Strength Indicator) signal of the BLE (Bluetooth Low Energy) Beacon as input data and made decisions to affiliate the zone of the current region as output. In order to verify the proposed method, we constructed an experimental environment similar in size to an actual rail station using four of the beacon and two zones.

최근 IoT환경에서 다양한 위치기반의 서비스의 확산으로 인해 실내측위는 중요한 영역으로 자리잡고 있다. 이에 본 논문에서는 특정 공간에 시설물, 서비스 등을 고려한 가상의 영역을 Zone으로 설정하였고, 다층퍼셉트론(MLP: Multi-Layer Perceptron)을 사용하여 Zone을 인식하는 방법을 제안하였다. 제안방법의 다층퍼셉트론은 입력으로 BLE(Bluetooth Low Energy) Beacon의 RSSI(Received Signal Strength Indicator)신호를 입력으로 활용하였고 현재 위치의 소속된 Zone을 출력하였다. 제안방법의 검증을 위해서 실제 역사와 유사한 크기의 실험환경을 구축하였으며 4개의 Beacon을 설치하였고 2개의 Zone영역을 설정하였다.
