The PHY layer complies with the IEEE 802.11a standard in the 5 GHz band [11].
This standard is based on the orthogonal frequency division multiplexing (OFDM) modulation scheme.
The maximum MAC payload size is assumed to be 1,500 bytes, and the PHY transmission rate is selected from the range 6–54 Mb/s, according to the wireless channel condition.
It is assumed that the offered traffic of STAs A and B is saturated (i.e., the transmission queues of STAs A and B are always nonempty) and that the size of the transmission queues of both STAs is infinite.
Moreover, it is assumed that any STA in the receiver mode can sense frames transmitted from the other STA and the capture effect does not occur (i.e., all STAs cannot obtain any information at the instant a frame collision occurs).
The frame error probability caused by thermal noise and interference signals is assumed to be negligible.
