Abstract |
Non-orthogonal multiple access (NOMA) has convincing potential to replace the conventional orthogonal frequency division multiple access (OFDMA) and single-carrier orthogonal division multiple access (SC-OFDMA). NOMA would therefore increase the spectrum efficiency and capacity of 3G and 4G/LTE networks either to 5G. Power allocation band multiple access amongst subscribers is the core concept behind NOMA. This article discusses numerous Ad hoc networks employing a variety of communication tools. We briefly go over Micrometers (MM) waves, Li-Fi communication (also known as visible light communication or VLC), and NOMA. Furthermore, NOMA adopting Successive Interference Cancellation (SIC) subsequent interference cancellation and power allocation principle are analyzed. Additionally, a detailed comparison of NOMA with OFDMA and NOMA is provided. The prospective areas for NOMA's future work in terms of Wireless Sensors Network (WSN) and the Internet of Things (IoT) are presented in the conclusion. |
