While RF energy harvesting enables energy efficient wireless communication, device-to-device (D2D) communication is an enabler for spectrum efficient wireless communication. In this paper, we aim to analyze the performance of RF energy harvesting based D2D communication in a point to point downlink simultaneous wireless information and power transfer (SWIPT) system with ambient RF transmitters. By using the stochastic geometry approach, the ambient RF transmitters are distributed as Ginibre a-determinantal point process (DPP) and Poisson point process (PPP). The D2D transmitters harvest energy from RF signals and use one of the channels assigned to cellular users, which is attributed to as D2D channel. This model investigated by using the prioritize spectrum access policy (PSA). In PSA, only D2D channels are used when all the other channels are occupied during transmission. The performance of this model is analyzed by simulating it in MATLAB and the results are averaged over 10,000 iterations. The simulation results are analyzed on the basis of different parameters by using both DPP and PPP. The results show that the DPP distribution is more effective in D2D communication with SWIPT transmission and energy harvesting than PPP.
