Spatially Robust Near-Field SWIPT Using Pinching Antennas: Rate-Energy Tradeoff Bounds
Zoran Hadzi-Velkov, Marija Poposka, Slavche Pejoski +1
Pinching Waveguide Antennas (PWAs) offer significant potential for simultaneous wireless information and power transfer (SWIPT) by enabling precise near-field energy focusing. Howe…
Designing Wireless Powered Networks assisted by Intelligent Reflecting Surfaces with Mechanical Tilt
Zoran Hadzi-Velkov, Slavche Pejoski, Nikola Zlatanov +1
In this paper, we propose a fairness-aware rate maximization scheme for a wireless powered communications network (WPCN) assisted by an intelligent reflecting surface (IRS). The pr…
Optimal Power and Time Allocation for WPCNs with Piece-wise Linear EH Model
Slavche Pejoski, Zoran Hadzi-Velkov, Robert Schober
We propose a novel transmission protocol for harvest-then-transmit wireless powered communication networks, which takes into account the non-linearity of the energy harvesting (EH)…
Wireless Powered Communication Networks with Non-Ideal Circuit Power Consumption
Slavche Pejoski, Zoran Hadzi-Velkov, Trung Q. Duong +1
Assuming non-ideal circuit power consumption at the energy harvesting (EH) nodes, we propose two practical protocols that optimize the performance of the harvest-then-transmit wire…
Proportional Fairness in ALOHA Networks with RF Energy Harvesting
Zoran Hadzi-Velkov, Slavche Pejoski, Nikola Zlatanov +1
In this paper, we study wireless powered communication networks that employ the slotted ALOHA protocol, which is the preferred protocol for simple and uncoordinated networks. In th…
