Well, I have wondered is it's possible to have an addressing scheme that's
split into two components - the "network location" and the "station ID".

The scheme works like this:

For routing purposes, the network ID is used to decide which node to send
packets to.

For applications, they are only interested in communicating with the device,
so they only talk in terms of the station ID.  However, the network sees the
packet address of having an address of network ID + station ID.

For fixed stations, they are configured with a fixed, non zero network ID
(or can be assigned one by a transform from things like GPS coordinates).
Each AP/routing node would have its own network ID, and the mojo system annd
the rest would still work.

Mobile stations would have a network ID of zero, which means "Get my network
ID from the nearest AP").  Their node ID would be non zero and unique, just
as in the case of routing nodes.

There might be a bit of broadcasting required when nodes move ("Is Station
xxxxxx out there"?), but once a connection is established, and/or nodes have
cached the location information, the routers would automatically attach the
mobile node's temporary network ID to the station ID for routing purposes...

Make sense?

Clear as mud?
