Quality-Aware Downlink Scalable Video Coding Multicasting using Non-Orthogonal Multiple Access in CRN Network

We suggest a fuzzy logic-based scheduling system that prioritises the transmission to various users by taking into account both the media content and the network's circumstances. Additionally, in order to enhance the quality of experience (QoE) that downstream users receive, an analytical model and statistical approach have been created for the aim of performing a quantitative study of the proposed scheduling algorithm for downlink SVC multicasting over CRN. In terms of the average weighted sum rate and the average quality of experience (QoE) of SUs, extensive simulation demonstrates that our proposed power allocation scheme for NOMA with QoS constraint outperforms the other two conventional schemes, namely NOMA fixed power allocation and NOMA without QoS constraint. Our research of how our suggested system stacks up against the two traditional methods led us to this conclusion.
