Wireless Powered Communication Networks with Backscatter Communication

2018
By 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.

Introduction to Wireless Powered Communication Network

2018
Wireless power transfer (WPT) plays a critical role in relaxing concerns related to limited operational lifetime of wireless networks. Different from traditional network devices, which rely on batteries for their energy need, devices in wireless powered communication networks (WPCNs) are able to scavenge energy from radio-frequency (RF) signals.

Optimization of Wireless Powered Communication Networks with Heterogeneous Nodes

2015 IEEE Global Communications Conference (GLOBECOM), 2014
This paper studies optimal resource allocation in a wireless powered communication network with two groups of users; one is assumed to have radio frequency (RF) energy harvesting capability and no other energy sources, while the other group has legacy nodes that are assumed not to have RF energy harvesting capability and are equipped with dedicated ...

Stochastic Optimal Control for Wireless Powered Communication Networks

IEEE Transactions on Wireless Communications, 2016
In this paper, we propose a stochastic optimal control algorithm for the wireless powered communication networks (WPCNs), in which the access point (AP) supplies energy to wireless nodes by means of the RF energy transfer technology. The energy beamforming is used to enhance the RF energy transfer efficiency by concentrating the radiated power on ...

Resource allocation techniques for wireless powered communication networks

2016 IEEE International Conference on Communications (ICC), 2016
This paper studies multi-user wireless powered communication networks, where energy constrained users scavenge energy of the radio frequency signals radiated from a hybrid access point (H-AP). The energy is then utilized for the users' uplink information transmission to the H-AP in time division multiple access mode.
