Since channel scanning time in IEEE 802.11 handoff is dominant in total handoff delay time, attention has to be paid to the reduction of channel scanning time for effectively supporting delay sensitive applications such as voice over IP (VoIP). Therefore, this paper proposes a new channel scanning scheme that adaptively adopts full channel scanning before, and first satisfaction first reservation...
When a Mobile Host (MH) moves out of the range of its current Basic Service Set (BSS), a request for handoff procedure will occur and then some delay associated with the handoff procedure, handoff delay, takes place. However, for the emerging multimedia streaming applications, delay sensitive applications, attention should be paid to the amount of this delay. In order to a fuller understanding of...
