[Tinyos-help] Intercept interface one question

[Funofnet funofnet]

Hi all !

I will be very thankful if someone explain to me intercept interface.

As it is mentioned:

The intercept interface signals that a message has been received, which is
supposed to be forwarded to another destination.

It returns TRUE if the packet should be forwarded, FALSE else.

What I understood is : Intercept.forward returns FLASE if a node snoops a
packet being transmitted.

 

******

To an additional clarification

"A" sends a message to "B" (which can be a root or "A"'s parent)

"C" is in the proximity of B or let's say in Tx range of the node A.

"C" can probably hear the packet being transmitted by "A" and can also snoop
it.

"C" is not qualified to forward "A" msg, then its Intercept.forward returns
FLASE consequently.

 

It is true???????

 

Thanks
