N2 - In this paper, we model and analyze a transmission strategy for Device-to-Device (D2D) terminals with ambient radio-frequency (RF) energy harvesting (EH). The D2D transmitters are powered by the ambient RF energy sources, and reuse the frequency bands with cellular users to communicate with corresponding receivers. Due to the duplex-constrain, D2D transmitters adopt time-switching mode for energy harvesting and data transmission. Stochastic geometry framework is used to model the distributions of D2D users and RF energy sources, and the expression for coverage probability of D2D link and cellular uplink are derived. Then we design the optimal harvestratio by maximizing the average coverage probability of D2D link under the constrain of guaranteeing the communication quality of the cellular link. Based on numerical results, the tradeoff between energy harvesting and data transmission is discussed under different system parameters, such as energy source density and D2D user density.
