Abstract
Device to Device (D2D) communication with content caching has recently been proposed as an exciting and innovative technology for next generation cellular networks. This paper presents a novel content caching and delivery method which allows multiple devices caching the same content and the content being sent via multiple devices to single device (MDSD) communication using D2D links to enhance user experience in terms of outage probability. A closed form expression of the outage probability is derived by considering how the content caching popularity affects achievable signal to interference plus noise ratio (SINR). The simulation and theoretical results show that as the popularity of the video increases, the outage probability of the system decreases substantially. On the other hand, the results show using MDSD enhances the SINR performance and decreases the outage probability of the system significantly.
