[Tinyos-help] [Broadcast and tree graph]

[Bernardo Avila Pires]

I suggest you look the tinyos tutorial, I think there might be
something useful about the IntToArfm (1.x) and BlinkToRadio (2.x). You
should define a sink component and a node component but most
importantly a message struct for this application. Once you get the
point about the BlinkToRadio you'll do it.
