A Novel Prioritization Scheme to Improve QoS in IEEE 802.11e Networks

Figure 9

Total throughput and total delay for five different scenarios with the same Gamma PDF mean but different variances ($n=24$). With variance increment, Intra-class contention takes place of Inter-class contention. (right): Total delay firstly decreases (gets better) and after a limit increases (gets worse). (left), Total throughput firstly increases (gets better) and after a limit decreases (gets worse).
