Simulation model of WLAN. We used QualNet 4.5.1; TCP SACK with delay-ACKs, Nagale algorithm, RFC1323, and Keepalive probes; maximum segment size was 1,500, bytes; send buffer size was 65,000 bytes; receive buffer size was 65,000, bytes; Access network is IEEE 802.11a WLAN with physical transmission rate of 24 Mbps; other links' bandwidth were 100 Mbps; RTT P was 10 ms while RTT o varied from 10 to 500 ms.
