Abstract

This paper describes an extension of the mobility support for the IPv6 protocol, which
is currently an Internet Draft. We argue that by processing geographical data information a
mobile node can efficiently switch between different LANs without disturbance to ongoing data
sessions. Furthermore the number of location update messages diminishes as the mobile node
transmits them only when switching to a new LAN. This extension requires that each router of
the foreign networks the mobile node visits, advertises the GPS coordinates of x points that
describe its region. It also requires that the mobile node is capable of receiving GPS signals.
Once having collected this information the mobile node can safely figure whether it will continue
to be served by the same LAN or it has to switch to a different one because soon it will be out of
the old LAN’s range. Furthermore using this information the mobile node can also decide to
which LAN it is preferable to switch. Lower-layer information, when it is available, such as
signal strength or signal quality can be used as auxiliary indications for the switch decision.
