The IEEE 802.11e standard allows for contention-based quality of service (QoS) provisioning using enhanced distributed channel access (EDCA). By tuning the contention parameters for EDCA, the system can adapt to changes in the network scenario. The benefits of this adaptation include the ability to maximise the system capacity while also achieving the service differentiation necessary to provide QoS. The use of fixed sized contention windows is one simple and effective way to improve EDCA… CONTINUE READING
