The whole point of doing Mobile IP at the network layers is that
nothing above it has to change (from a functionality point of view).
There are cases where the higher layers will want to be aware of the
change in bandwidth, delay, ... - but this is currently outside the
scope of Mobile IP it just gets the packets to the mobile (like any
good network layer should).

Note that there are various proposals for transport layer changes to
avoid performance problems when your links change characteristic, such
as when the error rate of a link (typically the last hop) changes
significantly.
