	abstract = {A complete handoff procedure of a mobile
node in wireless network includes access point
(AP) selection, call admission control (CAC),
and IP address allocation. Most current handoff
schemes only deal with the Layer-3 address
allocation, that is, the IP address re-allocation.
Without the integration with AP selection and
CAC, the mobile node (MN) may be
disconnected before a new IP address is
allocated, which makes seamless handoff
impracticable.
In this paper, an integrated system is
proposed. Firstly, AP selection is accomplished
by choosing the AP with the smallest number of
users associated with. We gather the information
of active users on each AP through the modified
beacon frames. Then, both call admission and a
new IP address pre-fetch are operated through
the DHCP relay simultaneously. Particularly,
Fairness-enhanced Limited Fractional Guard
Channel Policy (FLFGCP) for CAC scheme and
two additional thresholds, Dropping Probability
Threshold (DPT) and Blocking Probability
Threshold (BPT), are explicitly defined. Both
DPT and BPT are applied to balance the
dropping probability of handoff calls and
blocking probability of new calls respectively. An
OMNET++ simulation which demonstrates the
applicability of cooperating the AP selection and
call admission control for seamless handoff is
included.},
