Alocação Espacial de Power Beacons em Sistemas WET

This article investigates the joint optimization of \textit{Power Beacon} (PB) placement and energy \textit{beamforming} in Wireless Energy Transfer (WET) systems for IoT networks, aiming to minimize the total charging time and the devices' \textit{outage} probability. A scenario with multi-antenna PBs, analog \textit{beamforming}, statistical channel state information (SCSI), and a nonlinear energy harvesting model is considered. To this end, different clustering techniques are employed for PB placement. The results show that intelligent PB placement significantly improves system efficiency and reliability when compared with random strategies.
