- W2395944993 abstract "본 논문에서는 블루투스 4.0에서부터 지원하는 BLE(BlueTooth Low Energy) 프로토콜 장치인 iBeacon을 활용하여 사용자의 위치를 측정하는 시스템에서 추정 결과를 개선하는 기법을 연구하였다. iBeacon의 상황별 신호를 시스템을 통해 측정한 뒤 수집된 데이터 분석을 통하여 간섭 요인을 분석하고 보정을 위해 EKF(Extended Kalman Filter)를 적용하였다. 필터 적용 후 데이터와 기존 데이터와 비교하고, 추정 결과의 개선을 확인하였다. 제안하는 위치추정기법은 실제 구현에 복잡성이 적고, iBeacon 기본 환경의 취약한 위치 서비스 개선에 효과적이다. In this paper, by utilizing the iBeacon is BLE (BlueTooth Low Energy) protocol devices that are supported by over the Bluetooth 4.0, and have implemented a system to improve the accuracy in the system for measuring the position of the user. After measuring through the system according to the state of the iBeacon, the interference factors are analyzed through analysis of the collected data, and applying the extended Kalman filter for calibration. Compared with the data after applying a filter with existing data, it was confirmed an increase in accuracy. Improvement techniques for providing the less complexity to the actual implementation, is effective in improving the accuracy of vulnerable services basic iBeacon." @default.
