Аннотация

The distributed channel access coordination function of 802.11 can be problematic when one desires consistency in the channel access delay, or even bounded delay. PCF, EDCA and HCCA aim to partially remedy this situation, but it is unclear how much of an actual improvement they can provide and how well they work in practical situations. In this work your task would be to first get a good understanding of the state of the art of 802.11 channel access coordination, and using this, create a comparative study of the concrete effects of the individual mechanisms.
