Abstract
Currently, the most popular localization technology is global positioning system (GPS), which uses a satellite transmitting signal for localization and navigation. But this type of localization technology cannot localize in the buildings, because the signal is blocked by the structure. In order to address this type of problem, this thesis focuses on developing an indoor localization system. Currently, using RSSI (received signal strength indicator) for localization usually focuses on 2 dimensions (2D), but localization technology in 3 dimensions (3D) is becoming more important.he purpose of this thesis is to develop and construct a 2D and 3D localization system using RSSI as the index which is provided by the ZigBee platform. In this thesis, we use the concept of linear interpolation algorithm. The RSSI (received signal strength indicator) received from reference tags will be used to fill the whole sensing area, Following this, the Centroid method will be performed to calculate the predicted position of the tracking object in 2D and 3D space.
