Due to the development of state-of-the-art fifth-generation (5G) communication and Internet-of-Things (IoT), the demands for capacity and throughput of wireless networks have increased significantly. As a promising solution for this, a radio access technique namely non-orthogonal multiple access (NOMA) has been investigated. Particularly, in this paper, we analyze the system performance of a joint time allocation and power splitting (JTAPS) protocol for NOMA-based energy harvesting (EH) wireless networks over indoor scenarios which we modelled with log normal fading channels. Accordingly, to analyze the performance of such networks, we derive the analytical expression of a metric so-called ergodic outage probability. Then, thanks to Monte Carlo simulations done in Matlab, we are able to see the impact of different EH power splitting (PS) and EH time switching (TS) factors on the system performance indicated in terms of the ergodic outage probability. Last but not least, we plot the simulation results along with the theoretical results for comparison studies.
