DeuceScan: Deuce-Based Fast Handoff Scheme in IEEE 802.11 Wireless Networks

An Improved Inter-Domain Handover Scheme Based on a Bidirectional Cooperative Relay

“…As shown in Fig. 2, when MH reaches the edge of BS1, the received signal strength of MH continues to drop, and execute ( , ) S D α β algorithm [8] to determine the target access base station.…”

Opportunistic scanning: Interruption-free network topology discovery for wireless mesh networks

“…Their work, however, does not affect the delay associated with the handover process. While the original SyncScan algorithm only knows when a [3,4] combines neighborhood graphs with SyncScan hence reducing the scan attempts to channels where the probability to receive a beacon is high. Additionally, they use (geographic) position information of APs to estimate mobile's movement based on the radio signal strength indicator (RSSI) received from APs.…”

Empirical Evaluation of Overlap Requirements of Adjacent Radio Cells for Zero Delay Handover

“…in combination with Equations (7), (13), (15) to obtain the minimal required overlap ratio p min for zero delay handover…”

“…The underlying system model assumes that the decision when to switch from one AP to the other is based on a radio-signal-strength-based [10], [11] [12], [13] 0 ms n/a 0 ms n/a [14] [15], [16] 3.5 ms (plus 10 ms for channel switch) [17] 10 ms n/a (only single frequency networks; low user mobility) (RSM-based) algorithm. The latter employs a low-pass filter to equalized short term fading as well as an hysteresis margin to avoid oscillation of the station between two APs.…”
