Energy Accumulating Based Wireless Information and Power Transfer
2018 IEEE 23rd International Conference on Digital Signal Processing (DSP), 2018In this paper, a bidirectional wireless information and power transmission model with an energy accumulating relay is studied. To implement wireless information and power transmission simultaneously, a time-switching (TS) protocol is adopted. In addition, two energy harvesting (EH) protocols are proposed, named bidirectional continuous time EH (BI-CT ...

Cooperative bidding of data transmission and wireless energy transfer
2014 IEEE Wireless Communications and Networking Conference (WCNC), 2014This paper proposes a model and a mechanism for cooperative bidding of wireless data transmission and energy transfer in a decentralized wireless communication system. We aim to minimize the total number of packets waiting at wireless nodes and the total bid prices from the nodes.

Incentive Mechanism Design for Wireless Energy Transfer in IoT
2018 IEEE 29th Annual International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC), 2018Wireless energy transfer has been recently viewed as a promising solution to extend the operation time of wireless devices (e.g., sensors) for Internet of Things (IoT) system. In this paper, we formulate a business model and use the contract approach to study the energy transfer and pricing issue in IoT system, where the energy access point (EAP) gains

Wireless information and energy transfer under temperature constraints
2017 IEEE International Conference on Communications Workshops (ICC Workshops), 2017Wireless energy transfer causes heating in the surrounding tissue due to radiation. We address this issue in a joint wireless information and energy transfer setting. We consider the optimal joint wireless information and energy transfer subject to a peak temperature constraint at the receiver side in a deadline constrained frequency selective additive

Power transfer optimization of wireless energy harvesting system
6th IET International Conference on Power Electronics, Machines and Drives (PEMD 2012), 2012This paper will present a novel approach to the design of wireless energy transfer devices, by means of a recently developed evolutionary optimization method. This approach is well suited in order to increase the transfer efficiency and the robustness of the coupling, with the aim of minimizing the average power loss. (5 pages)

Wireless Transfer of Energy Alongside Information in Wireless Sensor Networks
2019Despite steady improvements over the last few decades, wireless communication networks are still severely constrained by the availability of an energy source. The problem manifests itself in many applications, in particular, wireless sensor networks enabling a plethora of Internet of Things devices, where communications are infrequent and the nodes are

Enhancing the Reliability of WSN Through Wireless Energy Transfer
2016Communication reliability is the ability of the network to last long enough without breaking communication between neighbouring nodes that relay information to the final destination. The transfer of energy from the base station to largely spatially distributed sensor nodes in a network with concurrent data transmission is studied.
