Improving TCP handoff performance in Mobile IP based networks

Mobile IP has been designed to support host mobility over the Internet. In this paper, we show that in most cases the smooth handoff by the route optimization of the Mobile IP standard cannot prevent degradation of TCP performance in events of handoffs, although it was originally intended to reduce the number of packets dropped during a handoff. We also show that in utilizing the route optimization extension, the TCP performance sometimes becomes worse even than the case of the base Mobile IP, if its smooth handoff fails to avoid losses of four or more packets during a handoff. To resolve such problems without sacri
