Abstract
Content caching between multiple devices to single device (MD2SD) using device to device (D2D) link is studied in this paper. A general outage probability for video content delivery using the popularity and storage size of the user equipment (UE) is derived. This outage probability is modelled as a function of popularity of video, storage size, and signal to interference plus noise ratio (SINR). Our main contribution is a closed form expression and a tractable approximation. The simulation results show that as the popularity of the video increases, the outage probability of the system decreases. It is also analysed that increasing the storage space on the UE decreases the outage probability of the system.
