This small project was done as part of our OpenHouse event during Tech Fest Shaastra2008 atIIT Madras. It's the first application of its kind I have written.
Please read my previous posts to understand basics, if you are not familiar with basic terms
Project : Target tracking using RSSI with TelosB
Types of nodes: Mobile node, Static nodes and base station
Tools: Java serialforwarder and customized extension of listen class
Routing protocol used: Collection
Tracking scenario: 1 Dimensional
The details
Mobile node will send a blank packet with specific interval while moving. The static nodes will catch that signal and measure the RSSI value. It will be transmitted to BaseStation. Base station is the multihoposcilloscope base. The value received by base station node can be read using java serialforwarder and Listen class.
However the Listen class gives only raw information. So the program is modified and customized to get values. RSSI values are scaled to a positive value. Value we have got are between 0 and 89 using telosb motes.
The GUI is having 10 grids with 6 static nodes, but can scale to any number of nodes.
