1 Wireless Tracking System Midcourse Design Review Team Members Ying W. Moy Mohammed A. Dastigir Hassan Malik Advisors Prof. Moritz Prof. Krishna Prof. Koren

2 12 December 2003ECE Senior Design Project2 Outline ► Introduction ► System Background ► Project Specifications ► Design Process ► Challenges & Solutions ► Progress  Demo ► Future Outlook

3 12 December 2003ECE Senior Design Project3 Introduction ► Question:  How can we establish an intelligent intrusion detection system that can monitor the movement of an object? ► Project Applications:  Intrusion Detection ► Building Security  Surveillance ► Environment Monitoring  Theft Deterrence ► For home, business, etc.

4 12 December 2003ECE Senior Design Project4 Introduction (…cont’d) ► Current Technology  Standard Motion Detectors ► simply detect motion ► no tracking  Infrared Heat Sensors ► affected by heat ► expensive  Global Positioning System ► not for practical application ► too expensive

5 12 December 2003ECE Senior Design Project5 Introduction (…cont’d) ► System Characteristics  Wireless  Small  Expandable  Reliable  Durable  Cost Effective  MICA Wireless Sensor Network

6 12 December 2003ECE Senior Design Project6 System Background ► What is a Mote?  Wireless communication device  Useful in many applications  “Smart Dust” ► How to interact with Mote  ► Wireless Motes equipped with MICA sensor board

7 12 December 2003ECE Senior Design Project7 MICA Sensorboard Isolate Magnetometer

8 12 December 2003ECE Senior Design Project8 Mote Specifications Processor/Radio Board MICA Mote (MPR300CB) Speed 4 MHz Flash 128 Kbytes SRAM 4K bytes EEPROM Serial Communication UART A/D 10 bit ADC Serial Flash 4 Mbit Radio Range 100 feet (more like 3.5) Radio Frequency 916 MHz Data Rate 40 Kbits/sec Power 0.75 mW

9 12 December 2003ECE Senior Design Project9 Project Specifications ► Configure Mote system to acquire magnetic field readings ► Transfer data from wireless sensor to base station ► Process data and create “tracking” application

10 12 December 2003ECE Senior Design Project10 Environment Mote magnet Data GUI Software Visual Representatio n Process Data TinyOS Application System Overview Diagram

11 12 December 2003ECE Senior Design Project11 Mote Configuration Magnetic Sensors Decode RF Module Magnet Base Station Block Diagram of Mote Process Mote Features: Honeywell HMC1002 Magnetic Field Range 30 Micro Gauss Programmed using TinyOS (NesC) to take in magnetic readings at time intervals Base Station: Take data from motes and hold data

12 12 December 2003ECE Senior Design Project12 GUI Application ► Serial forwarder retrieves data from serial port ► Socket Connection established between serial forwarder and Tracking Application ► Process data readings and visually track magnet motion

13 12 December 2003ECE Senior Design Project13 Challenges & Solutions ► Programming control of magnetometer sensor ► Wireless data packet transfer: Mote  Base Station ► Socket Communication between processes ► Interpreting data  Solution in progress

14 12 December 2003ECE Senior Design Project14 Current Status ► Mote configured to detect magnetic field and transmit data to Base Station via RF Module ► Connection established between Tracking Application and Base Station Process ► Tracking magnet in 1 dimension  Demo  Demo

15 12 December 2003ECE Senior Design Project15 Future Outlook ► Integrating and Controlling Multiple motes  Ad-hoc Network ► Modifications to Tracking Software  More accurate representation of magnet path  2 dimensional tracking  Revision of current features ► Investigate/consider other sensors
