WebApr 29, 2013 · THROUGH ANALYSIS AND CW. To improve the performance of the WLAN, IEEE 802.11e working group has proposed admission control (Achary et al., 2012b).The two entities play a major role in this admission control are; the QSTA that implement the QoS and QAP (Karanam et.al., 2006) that support the QoS.The proposed algorithm provides … Weband maximum contention window (CWmax). When the medium is sensed idle for an AIFS period, a WSTA waits for an additional random period known as a backoff period. This period is computed from the contention window (CW) value. CW is initially set to the CWmin. The backoff period (in multiple of time slots) is determined uniformly from the ...
