Content caching between multiple devices to single device (MD2SD) using device to device (D2D) link is studied for mobile communications 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 the closed form expression and a very close tractable approximation. From the simulation results, it can be observed that as the popularity of the video increases, the outage probability of the system can be decreased substantially. Furthermore, it is analysed that improving the storage space on the UE decreases the outage probability of the system.
