[ns] Hand-off option source code for ns

[Diepchi T Tran <Diepchi.T.Tran@lerc.nasa.gov>]

Hi,
I use ns to simulate a network including Mobile-IP. But ns does not support
the hand-off option yet. Do you have the handoff source code for ns or do
you know where I can get one?. Please help.
Thank you very much,
Cindy
