Can you tell me what you mean by the continuity of this process and how that
relates to the while loop?

This is pretty basic.  Have you read the TinyOS programming manual?  Have
you read the Timer TEP?

We don't mind helping but do like it much better when the homework has been
done.

That said.  Try using a periodic or restart the one shot from the .fired
event.
