Tim,
  What do you mean by saying most of the nodes are sleeping most of the
time.

Ian's question is much more insightful.  There is a big difference
between networks that have all of the routers awake all of the time and
a network where the routers sleep.

I have no idea which you mean.  I understand what Ian means.
