Figure 4From: Providing quality-of-service for frequency-aware Wi-Fi using OFDM-based variable-length Bloom filtersFalse positive probability of QoS-Fi. Under the evenly distributed traffic (ρ1:ρ2:ρ3:ρ4=0.25:0.25:0.25:0.25), with spectral leakage Pleak=0.1, number of subcarrier m=64. (a) The lengths of signatures (l i ) are l1:l2:l3:l4=16:8:6:4. (b) The lengths of signatures (l i ) are l1:l2:l3:l4=16:12:8:4.Back to article page
