PERFORMANCE ANALYSIS OF ENERGY HARVESTING NON-ORTHOGONAL MULTI-ACCESS NETWORKS WITH JAMMER

Abstract

Energy harvesting non-orthogonal multiple access (NOMA) networks effectively meet the demands for energy efficiency, spectral efficiency, and information reliability in modern communications. To enhance security performance, this paper studies an energy harvesting non-orthogonal multiple access model with eavesdropping devices (EHNOMAwJ). The paper employs a Monte Carlo simulation method to analyze the connection/security outage probability and the operational outage probability for both far and near receivers. The results indicate a trade-off between reliability and security. The paper further demonstrates that with an appropriate selection of the time/power splitting factor, this model achieves optimal security/reliability performance. Additionally, the results reveal that there are limits on the required transmission rate/security capacity to avoid complete disconnection and achieve full security. Furthermore, the impact of non-linear energy harvesting on communication reliability/information security is significant/small.
