In wireless communication networks, caching and delivering popular content via the device to device (D2D) communication has recently been proposed as an exciting and innovative technology in order to offload network data traffic. In this paper, a novel method of content delivery using multiple devices to the single device (MDSD) communication via D2D links is presented. An expression of the outage probability (Pout) is analytically derived and validated by simulation to determine the success of the content delivery to the user equipment (UE). Zipf distribution with exponent shape parameter p is adopted to model the UE requests and content caching popularity which affects the achievable link data rate (Ra). The results show that Pout decreases as the popularity of the content increases. Meanwhile, MDSD improves the UE experience in terms of Pout substantially compared to the single D2D link based method.
