A Novel Interference-aided RF Energy Harvesting scheme for Cooperative NOMA Network

This paper presents a novel scheme of Interference-aided RF Energy Harvesting in Cooperative NOMA system in presence of an Eavesdropper. Basic objective of this paper is to investigate the secrecy performance under the influence of a cluster of interferers under jamming cancellation scheme. The influence of various network parameters such as the Transmit Source Power, Nakagami-m parameter, Jamming Signal Power and the number of co-channel interferers on the system secrecy performance has been evaluated. Additionally, the impact of Power allocation Factor for varying Transmit Power of Source on the Ergodic Secrecy Rate has been found. The results of this paper illustrate how the jamming and interference power affect the secrecy performance. Furthermore, an optimal value of Source Signal-to-Interference-Noise Ratio at which the Secrecy Outage Probability is minimized has been found out for variation of Jamming and Interference Power Levels. This study can serve as a constraint on the optimal number of interfering nodes that can be utilized for energy harvesting to achieve a desired level of secrecy.
