Joint resource and power allocation for 5G enabled D2D networking with NOMA

Paramount data transfer among users in social groups and concerts imposes enormous traffic at the base station (BS), depleting the available resources and forcing fifth-generation (5G) researchers to seek communion with alternative technologies. Non-Orthogonal Multiple Access (NOMA) is determined as a potential technology for supporting multiple users on the same sub-channels using power domain multiplexing. Integration of NOMA with a Device-to-Device (D2D) communication technology provides lower latency for supporting proximity commu-nication. Significant research has been carried out till date in device pairing for resource allocation in NOMA and D2D. This paper proposes a joint resource and power allocation in the NOMA (JRPAN) algorithm for resource and power allocation to cellular and D2D users. Resources and power are adaptively assigned to the users depending upon the user's application. A proposal of group formation for resource reuse in NOMA with prior-itized user application is established. The Simulations have been performed to ascertain the fair allocation of resources to the users in conformity to the application. The proposed algorithm helps in conserving power as compared to orthogonal frequency division multiplexing (OFDMA) with the Hidden Markov Model (HMM). The results demonstrate that JRPAN achieves higher system throughput and saves power while ensuring the requirement of Quality of Experience and Quality of service in comparison to OFDMA-HMM and proportional algorithm.
