Cooperative Localization in Wireless Powered Communication Network
ICC 2021 - IEEE International Conference on Communications, 2021Large scale location management in wireless powered communication networks (WPCNs) can benefit the network performance, and it can also provide location based services for IoT applications without maintaining the batteries. However, it is difficult to attain accurate node positions only based on ranging information from anchors.

Power–Delay Tradeoff in Wireless Powered Communication Networks
IEEE Transactions on Vehicular Technology, 2017In this paper, we investigate the power–delay tradeoff for the newly emerging wireless powered communication networks, in which wireless powered devices (WPDs) harvest energy from a power station via wireless energy transfer in the downlink and then communicate with an information receiving station in the uplink.

Backscatter radio communication for wireless powered communication networks
2015 21st Asia-Pacific Conference on Communications (APCC), 2015Backscatter radio communication has become a newly emerging technique for low-rate, low-power and large-scale wireless sensor networks. As this promising technology enables a long-range communication for sensors with low power in a distributed area, it is desirable to support wireless powered communication networks (WPCNs) that experience doubly near ...

Hybrid backscatter communication for wireless powered communication networks
2016 International Symposium on Wireless Communication Systems (ISWCS), 2016We propose hybrid backscatter communication for wireless powered communication networks (WPCNs) to increase transmission range and provide uniform rate distribution in heterogeneous network (HetNet) environment. In such HetNet where the TV tower or high-power base station (macrocell) coexists with densely deployed small-power access points (e.g., small-

Stability Analysis of Wireless Powered Communication Networks
2020 Asia-Pacific International Symposium on Advanced Reliability and Maintenance Modeling (APARM), 2020In RF-based wireless powered communication networks (WPCNs), wireless devices can receive energy from electromagnetic waves radiated by dedicated energy transmitters or hybrid access points for operation. However, the energy charging rate at a wireless device is usually unstable or low because of time-varying characteristics of wireless channels or ...

Wireless Powered Communication Networks with Backscatter Communication
2018By exploiting the advantages of the harvest-then-transmit (HTT) mode and the BackCom mode, two schemes that integrating the HTT mode and the BackCom mode are proposed for the WPCN in this chapter, i.e., the hybrid user scheme and the hybrid mode scheme.
