Performance Analysis of Wireless Local Area Network for a High-/Low-Priority Traffic Ratio at Different Numbers of Access Categories

The performance of Wireless Local Area Network (WLAN) is highly dependent on the processes that are implemented in Medium Access Control (MAC) sublayer regulated by IEEE 802.11 standard. In turn, various parameters affect MAC sublayer, most important which number stations network and offered load. With massive growth multimedia traffic, research depending traffic types relevant. this paper, we present impact a high-/low-priority ratio WLAN with different numbers access categories. simulation results show wireless LANs network-sizes conditions. Performance large two categories prevalent high-priority significantly higher than case using four sublayer. This allows us to conclude improvement can be achieved an adaptive adjustment
