Ergodic Rate and Outage Analysis of Enhanced TS-SWIPT with Cooperative Relaying for NOMA Based UASNs

Résumé fourni par la source

A variety of maritime applications are supported by underwater acoustic sensor networks (UASNs), however their transmission bandwidth, dependability, and energy efficiency are constrained. To tackle these challenges, this study introduces an enhanced time-switching simultaneous wireless information and power transfer (ETS-SWIPT) framework incorporating cooperative relaying (CR) designed for non-orthogonal multiple access (NOMA). In UASNs, bandwidth is distance dependent and near user experience higher bandwidth than far user. We propose near user to utilize this additional bandwidth to harvest energy and also acts as a relay to support the far user. Analytical model for evaluating the ergodic rate and outage probability are developed and validated through simulation experiments. Results show that ETS-SWIPT with cooperative relaying improves energy efficiency and link reliability compared to the conventional approach.
