Wireless Sensor Networks and Privacy Osman Ceylan Istanbul Technical University

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 Ph. D, 2 Master, 15 Bs. C Students

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

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

Sensors Networks • Wireless communication • Small communication distance • Low power consumption

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

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

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)

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…

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

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

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