Device-to-device (D2D) communication can effectively meet the demands of high data rate by providing a direct link between two mobile users in cellular networks. In this paper, we analyze the optimal power control for energy efficiency of D2D communication underlaying cellular networks. Based on the stochastic geometry, we firstly use the homogeneous Poisson point process (PPP) to characterize the...
Device-to-device (D2D) communication is a promising technology for 5G wireless communication system. Since D2D communication usually reuses the resource of cellular users, interference management and resource allocation of D2D are the mainly research directions in D2D communication underlay cellular networks. The physical-layer security problem of D2D link is rarely under studied. In this paper, we...
This letter introduces a centralized joint power and admission control algorithm for cognitive radio networks. Its novelty lies in the proposed admission metric. Unlike those in existing algorithms, our metric predetermines the admission order of N secondary users which intend to access the network. This allows us to search a group of admitted secondary users with the bisection method. The proposed...
