Incremental Hybrid Decode-Amplify-Forward Source Retransmission Protocol for Outage Analysis of Relay-Assisted NOMA in PLC

Power line communication (PLC) is a desirable technology that has gained prominence with the help of present wired infrastructure. With the ability to decrease interference and improve device propagation performance, non-orthogonal multiple access (NOMA) has been developed as a novel multiple access system. This study proposes a hybrid protocol performed in NOMA based PLC with relay assistance. The relay aided NOMA for PLC system models are initially created using a source, relay, and destination. The proposed hybrid relaying strategy using Incremental Hybrid Decode-Amplify-Forward Source Retransmission (IHDAF-SR) for NOMA system to improve signal transmission rage. Moreover, the power allocation of proposed method is minimize the outage probability by using Adaptive Honey Badger Optimization (AHBO) algorithm. The results of simulation demonstrate that the proposed method improves performance in terms of power allocation of outage probability (0.0094), average complexity (0.145) and spectrum efficiency (0.845).
