Wireless powered sensor networks are composed of multiple sensor nodes with limited energy supply and storage. In this paper, we consider the wireless powered sensor networks, where an energy gateway can supply energy wirelessly to the sensor nodes. The sensor nodes use the energy to transmit their data. We then propose an opportunistic energy scheduling scheme. In this scheme, the energy gateway...
A wireless powered communication network is a potential application of wireless energy harvesting to improve convenience and flexibility. However, wireless energy transfer from a wireless energy source has to be scheduled to minimize energy usage while meeting quality of service (QoS) requirements of sensor nodes in the network. In this paper, we consider wireless powered sensor network whose sensor...
Radio frequency (RF) energy transfer and harvesting techniques have recently become alternative methods to power the next-generation wireless networks. As this emerging technology enables proactive energy replenishment of wireless devices, it is advantageous in supporting applications with quality-of-service requirements. In this paper, we present a comprehensive literature review on the research...
