In this paper, using the stochastic geometry theory, we present a frameworkfor analyzing the performance of device-to-device (D2D) communicationsunderlaid uplink (UL) cellular networks. In our analysis, we consider a D2Dmode selection criterion based on an energy threshold for each user equipment(UE). Specifically, a UE will operate in a cellular mode, if its receivedsignal strength from the strongest base station (BS) is large than a threshold\beta. Otherwise, it will operate in a D2D mode. Furthermore, we consider ageneralized log-normal shadowing in our analysis. The coverage probability andthe area spectral efficiency (ASE) are derived for both the cellular networkand the D2D one. Through our theoretical and numerical analyses, we quantifythe performance gains brought by D2D communications and provide guidelines ofselecting the parameters for network operations.
