What node provides the authenticator function?
Do you have that part in Contiki?  Your document says you run that on a Linux
system using hostapd.

How do you establish the radius shared secret for node A or B,
so that it can help enroll some future node E.  Or must it always go through
pre-established controller C?

If that's an intended limitation, then it can't work for enrolling nodes
in a route-over mesh, only for single-hop networks.
