Achieving service differentiation in IEEE 802.11e enhanced distributed channel access systems
The breakthrough reported in output-1 is applied to an IEEE 802.11e WiFi network using differentiated QoS. Three significant outcomes are achieved: the accurate modelling of 802.11e by p-CSMA; the optimization of 802.11e throughput performance; and a firmware implementation of 802.11e based on p-CSMA is proven. A major contribution of the research is the capability of the analysis to model collectively the EDCA features of transmission opportunities, internal collision resolution, AIFS differentiation and retry limits leading to more effective real-time optimization of throughput in a WiFi network. The method was applied in the FP7 project QoSMOS by BT (richard.mackenzie@bt.com).
