This paper focuses on energy efficiency of device-to-device (D2D) underlay massive multiple-input multiple-output (MIMO) hybrid networks with power beacons (PBs). The D2D transmitters harvest the energy from the signals of dedicated power beacons, but also the ambient radio frequency (RF) interference of cellular users (CUs). The inverse power control schemes are employed at D2D transmitters. For...
This paper focuses on a secrecy constrained massive multiple-input multiple-output (MIMO) relaying system in terms of the optimal design of system parameters such as the optimal total number of antennas at relay, where a more practical mixed analog-to-digital converters (ADCs) scheme, double-resolution ADCs scheme, is proposed. In the proposed double-resolution ADCs scheme, the total $M$ antennas...
Localized topology control is attractive for generating reduced topologies with desirable features such as sparser connectivity and reduced transmit powers. In this paper, we propose an energy efficient localized topology control algorithm called X-LMST in order to achieve prolonged network lifetime. In X-LMST, each node is required to keep its one-hop neighborhood topology. Moreover, in X-LMST, a...
