Improved quality of service utilising high priority traffic in HCF in a dynamically changing wireless networks
Amanda Peart, Mo Adda · 2008
The demands of the end users has changed in correlation to the advancement of technology, no longer will the end user accept long delays or a poor quality of service. Couple these requirements with the ever increasing demand for greater bandwidth to support such applications as streamed video and VoIP. Adequate Quality of Service (QoS) is now paramount within the dynamically changing nature of wireless networks that experience many issues, specifically in providing good and maintainable levels of QoS for high demand multimedia applications. This paper investigates how a finite bandwidth can be extended to accommodate additional users by utilising a proposed mechanism for the block-frame acknowledgement that exploits the IEEE 802.11 standard. This method takes advantage of the access categories encompassed in the Hybrid Coordination Function to prioritise traffic ensuring adequate quality of service, with no major upheaval
