Classifications in The Literature
Several ways of categorizing multiple-access schemes and protocols have been used in the literature. For example, Daniel Minoli (2009) identifies five principal types of multiple-access schemes: FDMA, TDMA, CDMA, SDMA, and Random access. R. Rom and M. Sidi (1990) categorize the protocols into Conflict-free access protocols, Aloha protocols, and Carrier Sensing protocols.
The Telecommunications Handbook (Terplan and Morreale, 2000) identifies the following MAC categories:
- Fixed assigned: TDMA, FDMA+WDMA, CDMA, SDMA
- Demand assigned (DA)
- Reservation: DA/TDMA, DA/FDMA+DA/WDMA, DA/CDMA, DA/SDMA
- Polling: Generalized polling, Distributed polling, Token Passing, Implicit polling, Slotted access
- Random access (RA): Pure RA (ALOHA, GRA), Adaptive RA (TRA), CSMA, CSMA/CD, CSMA/CA

Famous quotes containing the word literature:
“Our leading men are not of much account and never have been, but the average of the people is immense, beyond all history. Sometimes I think in all departments, literature and art included, that will be the way our superiority will exhibit itself. We will not have great individuals or great leaders, but a great average bulk, unprecedentedly great.”
—Walt Whitman (1819–1892)
