N2 - In this paper, we consider a device-to-device (D2D) wireless network, in which the wireless users act as helpers to provide the nearby users requested files through the D2D communication. We study an optimal caching strategy to minimize the outage probability where the co-channel interference among different D2D links is considered. In particular, we model the average file outage probability as a function of the signal-to-interference ratio (SINR), target data rate, capacity of caching storage, and file popularity with the assumption that users are randomly distributed by a Poisson point process (PPP). Simulation results show that our optimal caching strategy outperforms the existing ones in terms of average file outage probability.
