chance for all the devices.
When each priority queue waits for sending packets, it has to wait a fixed time AIFSN
and a random time CW. They define time values by multiple time slots. For 802.11b,
its time slot is 20ms. The time slot of 802.11a and 802.11g is 9 ms. CW insures the
random delay time of DCF, so that the packets collision among the devices with the
same access category can be avoided. If collision occurs, CW is doubled until it
exceeds its maximum value. After every successful transmission, CW returns to the
minimum value.
The priority queue that succeeds in the competition of sending packets will acquire
Txop time to send packets. If the txop value is 0, it is limited to be a MSDC (MAC
Service Data Unit).
