The Project:

The project goal conforms to the goal of SenSAR group founded in July 2003.

Develop underlying software/networking infrastructure for enabling sensor network applications

In particular, the project is to

Develop a locations tracking application for a small size wireless sensors network.

The project involves in a number of activities including:

• Get familiar with hardware components such as programming board, mica2, stargate, lego robot.
• Get familiar with tinyOS and developing applications under tinyOS using NesC
• Measure RSSI (Radio Signal Strength Indication)
• Implement localization algorithm (REKF) in Java.
• Make GUI in Java
• Carry out experiments

System Design

Plot graph estimation of all sensors positions

Estimation of sensors positions

Estimation of mobile robot path

Future works

• Improve the localization algorithm to
  Provide better estimation
• Develop further application using this
  Project results such as robot path planning
  And shadow tracking
