[Tinyos-devel] Fwd: Request for Comments: TEP 123 - Collection Tree Protocol

[Omprakash Gnawali]

Yes, we thought about this scenario. You see a few of these proposals
in the literature and TinyDB also did something similar - I am not
sure how well it worked. Our focus is on a practical protocol so we
could not say if hop-count based duty-cycling is feasible for the
protocols that can change parents at a given rate. If there is
evidence otherwise, we are open to putting the hop-count in the
routing frame.
