摘要

This paper investigates a new device-to-device (D2D) paradigm to evaluate system security at physical layer for the D2D link in which the energy harvesting-assisted node can communicate to satisfy quality of service (QoS) and help the conventional system with D2D capability against to eavesdropper. To cope with high security, the D2D deploys the lower layer with using cooperative jamming to eliminate impacts of illegal users. Considering relay node with capability of wireless energy harvesting, this paper attempts to investigate secure performance in case of power splitting fractions is controlled to improve the secrecy capacity. In particular, this work analyzes the secrecy capacities for direct connection, namely D2D links and traditional connections. As an important achievement, simulation results show the performance to deploy our proposed scheme to remain secure requirements in each D2D link in terms of the expected secrecy capacity.
