Today's wireless access networks consist of several
overlapping tiers. Provision of real time undisrupted
communication to mobile users, anywhere and anytime
through these heterogeneous overlay networks, is a
challenging task. This paper presents a handoff
technique for mobile devices equipped with dual mode
interfaces. The proposed mobile-controlled handoff
scheme reduces the service disruption time during both
horizontal as well as vertical handoffs. We exploit the IP
diversity created by the dual interfaces in the
overlapping area by simultaneously connecting to
different subnets or networks. Power saving is achieved
by activating both interfaces only during the handoff
period. The analysis shows that with proper network
engineering the service disruption during handoff can be
reduced significantly by exploiting the overlapping area
between subnets. With more powerful network interfaces
our proposal of dual interfaces can be realized.
