In IEEE 802.11 Medium Access Control (MAC) the Distributed Co-ordination Function (DCF) makes use of a simple CSMA (Carrier Sense Multiple Access) algorithm. When a station has a MAC frame to transmit, otherwise, the station must wait until the current transmission is complete before transmitting. The DCF does not include a Collision Detection function (i.e., CSMA/CD) since collision detection is not practical on a wireless network. In order to progress the performance of Medium Access Control (MAC) schemes in wireless communication networks, a number of researchers planned to take apart a single shared channel into numerous sub-channels: one as direct sub-channel and the others as data sub-channels.
