이동객체 위치획득시스템은 이동체데이터베이스((MODB : Moving Object Database)에서 위치를 획득하는 서브시스템으로써, 사람 또는 자동차와 같이 이동성을 갖는 객체의 위치를 여러 디바이스를 통해서 획득하는 역할을 한다. 이러한 위치획득시스템은 실시간으로 위치를 획득함에 있어서 통신 부하를 최소화하여야 하며, 획득된 정보의 질을 보장하여야 한다. 또한 다양한 데이터의 집합, 다양한 통신 환경 상황에 대하여 다양한 위치획득 모델을 적용할 수 있어야 하며, 어떠한 상황에서도 통신부하를 최소화하는 것을 목적으로 하고 있다. 정적 위치획득 전략, 거리기반 위치획득 전략, 그룹기반 위치획득 전략, 예측기반 위치획득 전략 등, 다양한 위치획득 전략을 모델링 하여 성능을 보장하여야 한다. 이에 본 논문에서는 이러한 다양한 위치획득 모델을 포함하고 있는 위치획득시스템을 구현하여 그 성능을 평가한다.
