QoE-driven peer discovery for D2D video communication

With the emerging demands for the large-scale services, Device-to-Device (D2D) communication has been viewed as a promising technology to improve the network capacity and user experience. In particular, the peer discovery is the first step to establish a D2D communication. Considering that quality of experience (QoE) is an important metric in video services, We propose a QoE-driven peer discovery strategy for D2D video communication. Extensive simulations demonstrate that the proposed scheme can achieve better discovering efficiency and higher QoE for D2D video communication.
