Abstract-- In our earlier study, we proposed SIGMA, a
Seamless IP diversity based Generalized Mobility Architecture.
SIGMA utilizes IP diversity to achieve a seamless handover of a
mobile host, and is designed to solve many of the drawbacks of
Mobile IP. In this paper, we evaluate the signaling cost of SIGMA
by using an analytical model. The signaling cost of SIGMA is also
compared with Hierarchical Mobile IPv6 (HMIPv6) by using the
proposed model. Various aspects that affect signaling cost, such
as mobile host moving speed, number of mobile host, number
