| Summary: | Traditional tracking system with Two Dimensions-image (2D-image) standard presents only few and dull information to users. In addition, 2D localization only supports one level platform (i.e. horizontally). Thus, the Three Dimensions (3D) location tracking system has been developed to support multilevel building. The aim of this research is to develop a positioning based indoor tracking system with 3D locations which are able to provide more useful location tracking information to users using radio signals. In this research, a Wireless Fidelity (Wi-Fi) based indoor location tracking approach is introduced. We used the existing Wireless Local Area Network (WLANs) attached devices called the Access Point (AP) to the edge of the wired network. Mobile Node (MN) communicates with the three APs to receive signals. The Receive Signal Strength Indicator (RSSI) is used to calculate the distance between MN and APs. To determine the location of the MN the trilateration method is used. Finally, the database file is developed to store all the results calculated by the location server. The location tracking system is able to detect positions of MN without using Global Positioning System. |
