[ns] Mobile IP blues

[Nauman Afzal]

Hi,
    I ran the script in Mar Gries' tutorial wireless3.tcl which deals with
Mobile IP, the question is how are the base station (i.e HA and FA in this
case) boundaries specified? I mean at what point does the  MH get FA's
beacon signals? Moreover, if I create another FA and make the node move
towards it will the handover take place itself or will I have to write a
script for it? Many thanks in advance,
Best,
Nauman
