Özet

The integration of slotted Aloha with power domain non-orthogonal multiple access (NOMA), dubbed slotted Aloha-NOMA (SAN) can emerge as an appealing MAC protocol to be used for Internet-of-Things (IoT) applications over 5G networks. In this paper, SAN is discussed, and its performance is evaluated in detail. The simulation results demonstrate that the maximum normalized throughput can be increased from 0.37, which is the case for slotted Aloha, to 1 by means of SAN. Specifically, this full throughput efficiency can be obtained at all low, medium and high network traffics. Besides that, the average delay can be significantly reduced compared to the slotted Aloha.
