Abstract

With the exponential increase of video traffic and content sharing applications on mobile devices such as smart phones and mobile tablets, Device-to-Device (D2D) technique has become attractive in the application to content delivery since it can effectively improve the resource efficiency of cellular network using proximal transmission. In this paper, we investigate D2D multicast content delivery in cellular networks. We first propose a multicast architecture for D2D content delivery, and then analyze the numbers of UEs caching a content and requesting a content, respectively. With these analyses, we obtain the number of content requests in the network which is served by D2D content delivery, and provides a tool for evaluating the performance of D2D delivery. Besides, we provide the average serving time through D2D multicast content delivery. Finally, we have performed simulation, and the results show delivery performance under different transmission parameters and validate the proposed theory. The work presented in this paper demonstrates that the proposed architecture and methods are the concrete implementation of D2D communication technique for the application to content sharing with the achievement to improve the resource efficiency of cellular networks.
