The IEEE-802.11e standard was published withthe goal of ensuring quality of service, especially with mul-timedia data. However, this standard only assigns differentpriorities for different types of data but does not controlthe sharing of bandwidth among different data flows. In thispaper, we will propose a method of sharing bandwidth forproportional data flows and controlling Contention Windowof each priority flow to achieve that ratio.
