Abstract

This work introduces an alternative WLAN protocol which could be adapted in the HCF scheme defined by IEEE 802.11, in place of the HCCA mechanism. POAC-QG (priority oriented adaptive control with QoS guarantee) is a complete centralized channel access mechanism, it is able to guarantee QoS for all types of multimedia network applications, it enhances the parameterized traffic with priorities, and it supports time division access using slots. It instantly negotiates the quality levels of the traffic streams trying to support multiple streams with best possible quality. POAC-QG, compared with HCCA, exhibits generally superior performance
