Mobile IP is a standard for handling routing for hosts that have moved from
their home network. This paper studies the costs of the Mobile IP handoff
that occurs when a mobile host moves between networks. Experiments were car
ried out with Mobile IP and TCP over varying network conditions to observe
the effect of handoffs on the transmission. This paper shows that although
Mobile IP may be appropriate for current applications, its long handoff per
iods make it unsuitable for the future.
