Mohammed,

it's very good that you point to related work that you did.

Still, I refer to the discussion that Thomas and I had yesterday on the 
differences between network-assisted mobility (which is what you have 
experimented with) and end-to-end mobility (which is what our analysis 
is about).

To be brief:  Our work is truly orthogonal.

Further, I should mention that our analysis assumes the use of DNA 
mechanisms (DNA protocol, CPL, FastRA) to eliminate router-discovery and 
movement-detection delays during reactive handoffs, Optimistic DAD to 
get rid of the address-configuration latency, and Media Independent 
Handover Services (including Information Services) to facilitate 
proactive handoffs.

Hope this makes things more clear.

Regards,
- Christian
