Overlaid device-to-device communication in cellular networks

Abstract

We present an analytical characterization of the spectral efficiency achievable by D2D communication links overlaid on a cellular network. The analysis relies on a stochastic geometry formulation with a novel approach to the modeling and spatial averaging of interference, which facilitates obtaining compact expressions. These expressions are then applied to gauge the potential of D2D communication, which is found to be very sizeable in situations of strong traffic locality.
