Due to the openness of the physical layer, the physical layer security has been widely discussed. It is considered as an effective way to improve the secrecy rate that we add artificial noise to D2D communications underlaying cellular networks. Compared to previous studies, in this paper we not only think of the situation where artificial noise is added to the original communication signal between...
With the combination of device-to-device (D2D) communication and millimeter wave (mmWave) technology, the density of communication devices increases greatly and the communication environment becomes more complicated. A key challenge in such networks is interference, which is not only from main lobe, but also from the sidelobe power accumulation. However, the approaches for resource allocation in traditional...
Device-to-device (D2D) communication has been widely studied to improve network performance and been considered as a potential technological component for the next generation communication. As Quality of Experience (QoE) is the major determining factor for the media service, we aim at promoting user's QoE Mean of Score (MOS) value for dynamic cellular networks. In this paper, we focus on the problem...
In cellular networks, the proximity devices may share files directly without going through the eNBs, which is called Device-to-Device communications (D2D). It has been considered as a potential technological component for the next generation of communication. In this paper, we investigate a novel framework to distribute video files from some other proximity devices through users' media cloud assisted...
