Interactive Wireless Charging for Energy Balance

Abstract

We study how to efficiently transfer energy wirelessly in ad hoc networks of battery-limited devices, toward prolonging their lifetime. In contrast to the stateof-the-art, we assume a much weaker population of distributed devices which are exchanging energy in a "peer to peer", bi-directional manner with each other, without any special charger nodes. We address a quite general case of diverse energy levels and priorities in the network and study the problem of how the system can efficiently reach a weighted energy balance state distributively, under both loss-less and lossy power transfer assumptions. Three protocols are designed, analyzed, and evaluated, achieving different performance trade-offs between energy balance quality, convergence time, and energy efficiency.

Long Distance Power Transfer Technique: A Review

“…It is gotten by the receiving wire at the rectenna, at which the microwave radiation goes through a low pass channel at that point a coordinating system at that point a rectifier. It is changed over to DC control (Nikoletseas et al, 2016) the subtleties of the pertinent advances are portrayed in the segment to follow. Strategy with higher recurrence transmission and complete example estimations (Bush, 2014).…”

“…It has been modified from site 5 to 8 GHz interpreters redirected control in it (Han et al, 2016). A communication channel is opened in between the wireless power source primary power is used to charge its battery the double frequency printing in it has whimsy been used retina (Nikoletseas et al, 2016). Essentially the dispatching coil is formed from 20 cm to 20 cm in jugate the power distribution system.…”

An algorithmic study in the vector model for Wireless Power Transfer maximization

“…Also, the book [11], is the first systematic exposition on the domain of wireless energy transfer in ad hoc communication networks. Several works study applications in sensor networks [12,13,14] and wireless distributed systems [15,16], UAVs [17,18]. Different to all those works, in this article we investigate a static setting, where transmitter and receiver locations are predefined and stationary, and there are no mobile elements in the system.…”

Wireless charging for weighted energy balance in populations of mobile peers

“…• We continue and extend the model of interactive wireless charging, presented in [8]. We present a problem statement regarding population weighted energy balance.…”

“…For example, the same antenna, designed to exploit its far-field properties for communication purposes, can be suitably configured for simultaneously realizing wireless energy transfer via its near-field properties. The near-field behavior of a pair of closely coupled transmitting and receiving dual-band printed monopole antennas (suitable for mobile phone applications) can make it possible to achieve both far-field performance and near-field power transfer efficiency (from 35% to 10%) for mobile phones located few centimeters A preliminary version of this paper appeared in [8]. * Corresponding author at: Institute for Informatics and Telematics, National Research Council, Via G.
