Abstract In this paper, a novel fairness-aware harvested energy efficiency-based green transmission scheme for wireless
information and power transfer (SWIPT) aided sensor networks is developed for active beamforming of multiantenna transmitter and passive beamforming at intelligent reflecting surfaces (IRS). By optimizing the active
beamformer assignment at the transmitter in conjunction with the passive beamformer assignment at the IRS, we
aim to maximize the minimum harvested energy efficiency among all the energy receivers (ER) where information
receivers (IR) are bound to the signal-interference-noise-ratio (SINR) and the maximum transmitted power of
the transmitter. To handle the non-convex problem, both semi-definite relaxation (SDR) and… More >
