Abstract-- IP mobility can be handled at different layers of
the protocol stack. Mobile IP has been developed to handle
mobility of Internet hosts at the network layer. As an alternative
solution, a number of transport layer mobility protocols have
been proposed. However, the location management schemes used
in these transport layer solutions are not suitable for frequent
mobile handovers due to user's high mobility. In this paper, we
propose HiSIGMA, a hierarchical location management scheme
for transport layer mobility schemes. We used an analytical
model to evaluate HiSIGMA using signaling cost as the perfor-
