Multimedia streaming using D2D in 5G ultra dense networks

Device-to-Device (D2D) communication has been proposed as a promising technique to improve resource utilization in fifth generation (5G) cellular networks by offloading the traffic from backhaul to local direct links. The throughput for delivery of multimedia content can be greatly enhanced by D2D communications, where direct links between pairs of user devices are set up without involving a central base station. In this paper, we propose the scheduling algorithms for effectively sharing the multimedia content using D2D communication. The proposed algorithms ensure the liveness for live video streaming while reducing the stall events for on-demand video streaming. Through extensive simulation, the proposed approaches are shown to provide sizeable gains compared with existing solution.
