[Tinyos-help] set distance between motes in tinyviz

[Darren BISHOP]

Hey Nilay,

In TinyViz goto the 'Plugins' menu and enable the 'Radio model' plugin. 
Select the corresponding control panel (on the right) and choose the 
radio range e.g. 'Fixed radius (10.0)'. You can then scale this by 
setting the 'Distance scaling factor'; I believe you must use the 
reciprocal of the factor by which you wish to scale.

Hope this helps.
