Abstract
This thesis presents an 802.11-based positioning system developed and demonstrated in the Taipei Children's Museum of Transportation and Communication. The proposed positioning system partitions the service area into several regions, and the goal of the proposed positioning system is to correctly locate the locations of the visitors. The proposed system would use signal strength signature which contains a sequence of access point IDs with the average power strength measured in each direction of each reference point, so signal strength signatures will be collected in each reference point in the proposed positioning system. In the positioning, the proposed positioning system will locate visitors via the collection of power strengths of the visitors’ positions, and then applies the proposed positioning method called region score comparison (RSC) positioning method to determine the regions which the visitors are located in. A location database called the region database (RDB) is applied to store and maintain the signal strength signatures in each reference point. The experimental results validate that the location information provided by the proposed positioning system assures high correctness of region classification.
