Daniel,
I think there is one requirement missing, which should state that
"reduced-function devices" are not to be involved in any mobility related
signaling.
Why ? Should RFD be a stationary mode only in 6lowpan area ? Can you
elaborate on your concern again ?
Daniel Park
What I meant is that reduced-function devices should be able to move without
having to involve actively in any mobility protocol. Even though the
separation between RFDs and FFDs is pointed out in the draft, I could not
see whether different mobility-related requirements apply to them or not.
For example the draft makes these two statements:
- "The lowpan nodes must be able to detect its movement from one wireless
LowPan to another correctly."
- "When a lowpan node moves from one personal area network(6lowpan) to
another, it should immediately inform the new PAN co-ordinator about its
presence."
In my opinion, RFD nodes should not have to detect their own movement. Their
movement should *be detected* by more capable devices... what do you think?
Best regards,
Dominik
