- 1. Automated Location Tracking Using Bluetooth Submitted by UdayAnanthAkhilaAthreshAbhijeetYatgiri
- 2. AbstractLocation Tracking is crucial in providing visibility of mobile nodes.Better Control, higher productivityTraditional Tracking – Global Positioning System(GPS) Alternate Tracking for smaller geography -Bluetooth
- 3. ObjectiveTo track human location in signal sensitive area using Bluetooth. Constantly monitor the locationProvide consistent information regarding user whereabouts.Support duplex communication between mobile nodes and server
- 5. Hardware Requirements(per node basis)Intel Core2Duo e8200 (2.66 GHz) (Lower end processors can be used as well)2GB RAM DDR2 (A minimum of 512 MB required)Intel dp35dp ChipsetLAN (Ethernet) CardSilicon Cambridge Bluetooth Radio (Dongle)Bluetooth Enabled Cellular Phones.

- 14. Bluetooth
- 15. Bluetooth Open Specification, Wireless StandardShort range radio technology(2.4 Ghz) for ad hoc communication of voice and data transferCreation of PANs Range: 10 m for low end, 100 m high end Bluetooth devices
- 16. Bluetooth Stack
- 17. Radio layer : lowest layer, controls transceiver's requirements and signals Baseband : physical RF links b/w devices, channel processing, timing, channel access control.Link Manager: Link control, Baseband packet size, Authentication.
- 18. HCI : command interface for the below layers, can access hardware status, control registersL2CAP : abstracts uppers layers from the lower layersSDP : Protocol for querying, searching services
- 19. RFCOMM : Serial port emulatorOBEX : Similar to HTTP but used in low end devices. Pushing data to mobile nodes.
- 20. Device DiscoveryA Bluetooth device dynamically detects other Bluetooth devices in it’s vicinity –Device Discovery (Inquiry)It should also be able to detect services that are running on these detected devices –Service DiscoveryDevices can be set to ‘general’ mode , ‘non- discoverable’ mode or ‘limited’ mode.When issued an inquiry only discoverable devices respond back to the initiator with a 6 byte address
- 22. A Bluetooth Server is one that’s running JABWT application and can provide services to Client via BluetoothThe Bluetooth Stack provides Services Discovery Database (SDDB) : Contains all the services provided by server and accessible by client via Service Discovery Protocol (SDP) query
- 23. List of all the services provided are stored as Services Records and are indexed using unique identifiers.Server has to register all the services it can provide.
- 24. JAVA
- 25. Java provides a standardized and portable interface.Maintains a clean memory with automatic garbage collection.Capable of providing a simplistic User Interface.Scalable by including external upgrades and packages.
- 26. FRONT ENDJava Swings has been used to design the User Interface(UI) for this applicationSwing is a set of classes that provides more powerful and flexible components than those provided by traditional AWT .Several additional components like tabbed panes, trees ,tables etc are provided in Swings.
- 29. JSR 82Provides an interface to the Bluetooth host controller.Interfaces the Bluetooth Stack and Application Program.Supports the use of custom built stacks following the JSR-82 specifications
- 30. BACK END
- 32. J2EEProvides access to Database Backend of the Application.Provides Connectors to link up with specific vendors.Simplifies connectivity by using a Type 4 Connector.Provides a substantial Stack Trace to diagnose errors.

- 38. Future Aspects
- 39. Provide an option of Scalability with high powered Bluetooth Radios.Integration of Real time and IP Traffic.Triangulation facilities through an isometric layout of the network.Integration with security and automation services.
- 40. Limitations
- 41. The range of low powered Bluetooth radios are limited to 10 meters.Overlapping of Radio coverage can lead to ambiguity.Latency and overhead involved using Bluetooth is higher than traditional networks.Tight coupling of the Bluetooth protocol stack with the governing application prevents optimization.
