Master's Thesis :
"Localization and Surveillance using Wireless Sensor Network and Pan/Tilt Camera"
- Studied and tested various wireless sensor motes such as MICA2, MICAz and Cricket for localization algorithms; TinyOs and nesC were used for initial Radio Signal Strength Indicator (RSSI) based experiments.
- Successfully localized an object with centimeters accuracy in indoor environment using Time Difference of Arrival (TDoA) approach, which utilizes combination RF and Ultrasound signal to get distance.
- Developed and implemented algorithm to move pan/tilt camera frame towards the object using the location results obtained from the sensor network; even achieved surveillance results in centimeter accuracy.
- Used Java and Linux as platform to interface wireless sensor network and camera system; calculate the location of the object and the pan/tilt angles for the camera.
- Proposed integration of this research with sensor web for future ware and intelligent Internet. [pdf]
