4 The existing system used 2D tracking system. The 2D location tracking mechanism only supports tracking the mobile unit position in the same level. Enhance into 3D version. The 3D location tracking mechanism is globally supported to track the mobile unit everywhere, even in different level. 4

6 To develop 3D location tracking system for mobile units at several services level 6

8 Location Tracking great importance since World War II, when military planners realized its usefulness for targeting, fleet management, positioning, and navigation. it is the convergence of several technologies that can be merged to create systems that track inventory, livestock or vehicle fleets. Similaril systemscan be created dto deliverlocation based l d services to wireless devices. Current technologies being used to create location tracking and location based systems include Geographic Information Systems (GIS), Global Positioning System (GPS), Radio Frequency Identification (RFID), and Wireless Local Area Network (WLAN). Location tracking or location based service system will use one or a combination of these technologies. 8

9 The system requires that a node or tag be placed on the object, animal or person being tracked. For eamplethe example, GPS receiverer in a cell phone or an RFID tag on a DVD can be used to track those devices with a detection system such as GPS satellites or RFID receivers. Location tracking in an indoor environment is possible with various techniques based on mechanical, acoustical, ultrasonic, optical, infrared, inertial or radio signal measurements. Global Positioning System (GPS) is one of famous tracking system as a feasible and effective outdoor tracking system. location tracking information and visualization of 3D graphics either in outdoor or indoor environment had been presented as one of research issues. 9

10 WLAN A wireless local area network (WLAN) links two or more devices using some wireless distribution method (typically spreadspectrum or OFDM radio), and usually providing a connection through an access point to the wider internet. gives users the mobility to move around within a local coverage area and still be connected to the network. becomepopularinthehomeduetoeaseofinstallation,andthe increasing popularity of laptop computers. Public businesses such as coffee shops and malls have begun to offer wireless access to their customers, sometimes for free. Large wireless network projects are being put up in many major cities: New York City, for instance, has begun a pilot program to cover all five boroughs of the city with wireless Internet access. 10

11 RSSI received signal strength indication (RSSI) is a measurement of the power present in a received radio signal. generic radio receiver technology metric, which is usually invisible to the user of device containing the receiver, but is directly known to users of wireless networking of IEEE protocol lfamily. In an IEEE system, RSSI is the relative received signal strength in a wireless environment, in arbitrary units. Theend user will likely observe an RSSI value when measuring the signal strength of a wireless network through the use of a wireless network monitoring tool like Wireshark, Wildpacket, Kismet or Inssider. 11

12 METHODOLOGY 12

13 Proximity Method 13

14 considered as a robust method to track object against electromagneticnoise, i especially ill id indoors. tracking object will be located once a base station can sense signal from such object which means it has been in an area covered by such base station. Low cost. Vision & Media Computing Lab. of Nara institute is a sample of tracking systems using proximity method by using IR sensors, RF tags, and etc. cannot estimate exact coordination of any objects but the area the object is located. 14

15 Scene Analysis Method 15

16 Scene Analysis Method analysis real area in order to measure signal strength of an object at all coordination of such area and store the data into a database. Once the system tracks any objects, the signal strength received from such object will be compared with ones in the database in order to find n nearest coordination and use them to estimate t location of the tracking object. The number of coordination depends upon a size of area and a size of grid the smaller size of grid, the higher the accuracy. becomes a hard work, especially in a large area and a small size of grid. the signal is measured on real site, the location estimation by scene analysis has high accuracy. 16

17 Triangulation Method 17

18 needs at least three base stations and play a role in sensing the strength of signal received from an interesting object. uses RSSI to get signals from the base stations. Three values of signal strength will be converted to three distance values from the object to all three base stations and will be used to estimate the location of the object by drawing three circles, which have all three base stations as a center point of each circle. The radius of each circle equalsthedistancewehavecalculated from the signal strength. The intersection of all three circles will be an estimated location of the tracking object.

28 CONCLUSIONS 28

29 the development of performance analysis of location tracking system for multiple levels to track the position of the mobile unit. The 3D system has been developed d to replace the traditional 2D standard floor map. The triangulation method had been choosen because of the low cost. the accuracy of the 3D system achieved is about six meters. Our next steps will be integrating the switching device. The device switching is support to switch session from one device to another using mobile node. 29
