Channel scanning is an important aspect of seamless handovers since it is required in order
to find a target point of attachment (PoA). In the IEEE 802.11 WLAN, scanning of other
channels causes service disruptions with the current AP so that the provided quality of
service (QoS) will be degraded seriously during the handoff. In this paper, we propose a
QoS supported dynamic channel scanning algorithm. The scanning period is scheduled to
guarantee the user's QoS requirements while the scan progresses. The simulation results …
