Interactive Wireless Charging for Weighted Energy Balance

Abstract

We study how to efficiently transfer energy wirelessly in ad hoc networks of battery-limited devices, towards prolonging their lifetime. We assume a weak population of distributed devices which are exchanging energy in a "peer-topeer", manner with each other. 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. We present three protocols that achieve different performance trade-offs between energy balance quality, convergence time and energy efficiency.
