mSIGMA: An Efficient Handoff Scheme
for Multiclass Networks
Abu (Sayeem) Reaz, Shaojian Fu, Sifat Ferdousi, and Mohammed Atiquzzaman, Senior Member, IEEE
Abstract--Wireless networks are becoming more heterogeneous;
different classes of networks coexist and users want to connect to
any available network, anytime. So, it is important to have a mo-
bility management scheme that can manage handoff for both in-
terclass and intraclass mobility so that the users can connect to
and roam between any network. We propose an end-to-end mo-
bility management scheme, Multiclass SIGMA ( mSIGMA), that
performs soft handoff for interclass and intraclass mobility in wire-
less network and can perform low-loss location management. Our
analysis shows mSIGMA can perform seamless handoff across net-
works with low delay and packet loss with efficient location man-
agement. We have also shown though experimental analysis that
mSIGMA is implementable with existing networking technologies
and can perform handoff efficiently.
Index Terms--Mobility management, multiclass network, ver-
tical handoff.
