Abstract

Recently, LBS(Location Based Service) which provides useful service based on the location of objects or human has drawn the attention of the research community. To provide LBS, many researchers have proposed many localization systems such as Cricket or Ubisense, however, these systems have the limit that it is very hard to perform the complicated computation on these systems because these systems consist of sensor nodes which have very limited computing power. In the paper, we propose a new localization system with the gateway node which has very high computing power and resource which is suitable for the complicated computation needed for localization.

최근 언제 어디서나 사람과 사물 같은 객체의 위치를 인식하고, 이를 기반으로 유용한 서비스를 제공하는 LBS(Location Based Service)가 대두되고 있다. LBS를 제공하기 위해 Cricket, Ubisense 등의 많은 연구가 진행되고 있지만, 이들은 노드들로만 구성된 네트워크를 이용하기 때문에 위치추적과 같은 복잡한 연산을 수행하는데 적합하지 않다. 본 연구는 위치 인식이 가능하고, 계산 능력이 높은 게이트웨이 노드를 구현하여 복잡한 연산을 가능하게 하였다.
