1. Wireless Sensor Networks and Privacy Osman Ceylan Istanbul Technical University

2. ITU RF Electronics Laboratory Istanbul Technical University Faculty of Electrics – Electronics Department of Electronics and Communication RF System and Circuit Designs Radars Sensor Networks Mini-Satellites Ultra Wideband RF Power Amplifiers 2 PhD, 2 Master, 15 BsC Students

3. Node Works with battery Communicates by Wireless Includes sensors Cheap and flexible

4. Sensors on a Node Temperature Sound Vibration Acceleration Magnetic Field Pressure Humidity Light RF Power Ultrasonic TX/RX

5. Sensors Networks Wireless communication Small communication distance Low power consumption

6. Sensor Networks for Automation Building Automation Building or Area Security Border Security Monitoring Machine Health Agriculture

7. Security Problems Communication is wireless! Common communication protocols Less encryption COST SECURITY SIZE OF NODES COMMUNICATION SPEED

8. Building Automation with Sensor Networks Production Automation Device Control Temperature/Humidity Control Worker and Device Tracking Quality Control Production Counting Sensors Temperature/Humidity/Pressure Sound Camera Motion RISKS Taking Photos from Building (Privacy Problem) Determine the Number of People Inside (Security Problem)

9. Machine Automation with Sensor Networks Home Automation Light Control Temperature Control Security Baby or Animal Tracking Sensors Temperature Humidity Sound Camera Motion RISKS Company Data can be stolen! Photos from inside…

10. Security Problem Determination is very difficult. More encyrption is necessary More bandwitdh More operating cost

11. What is the solution? We need automation! We need security! We want low cost!

12. There is no unique solution! COST Determine requirements Sensor types Number of nodes Decide security level Choose your nodes Find optimum
