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 compare the handover latency
of SIGMA and recent MIPv6 enhancements, namely, FMIPv6,
HMIPv6, and FHMIPv6. Various parameters are considered
such as layer 2 handover/setup latency, IP address resolution
latency, layer 2 beacon period, and mobile host moving speed.
Our results show that SIGMA handover latency is insensitive to
layer 2 setup latency, IP address resolution latency and beacon
periods. Moreover, SIGMA is able to seamlessly handle relatively
high speed movement of mobile host.
