Abstract

Currently, the importance of location-based services and location awareness has been grown due to the advancement of wireless communication technologies. Among several localization techniques, the trilateration localization is one of major localization techniques. However, distance estimation errors caused by obstacles and indoor environment changes lead to inaccurate localization. Although there are existing trilateration localization methods, they have focused on addressing a few problems of trilateration location approaches without detailed analysis. This paper analyzes existing trilateration location methods and evaluate their performance.

현재 무선 통신기술의 발전으로 위치기반 서비스 및 위치 인식의 중요성이 증가하는 추세이다. 여러 위치 인식 기법 중에서 삼변측량 기법이 대표적이다. 그러나 삼변측량 기법에서는 장애물이나 실내 주변 환경의 변화로 인하여 거리 오차가 발생하면 정확한 위치 인식을 할 수 없다. 위치 인식을 향상시키는 기존 삼변 측량 인식 기법에 대한 연구가 많이 있었지만, 삼변측량 위치인식 기법에 대한 체계적인 분석을 하지 않았다. 본 논문에서는 기존의 삼변측량 위치인식 기법들을 분석하고, 거리오차로 인해 위치 인식의 오차를 줄이는 기법들을 평가하였다.
