Title: Efficient wireless power transfer for Internet of Things devices

Abstract: The Internet of Things (IoT) is an emerging computing paradigm that consists of devices coupled with internet connectivity without human interaction. It is projected that in the near future, common industrial, personal, office and household devices, machines and objects will hold the ability to sense, communicate and process information ubiquitously. The ever-growing increase in modern and ubiquitous applications of IoT are causing energy scarcity, which is a serious threat to the lifetime of the network. Wireless power transfer emerges as a promising solution to replenish the IoT devices. In wireless power transfer, energy is transferred to sensor nodes through dedicated energy transmitters. In this talk, we will first give a brief overview of IoT and requirements and challenges of wireless power transfer. We then present a mechanism to place energy transmitters and determine a minimum number of energy transmitters. This talk offers an energy-efficient scheduling scheme for energy transmitters. The focus is to minimize the energy consumption of energy transmitters while keeping sensor nodes sufficiently charged. Finally, we provide simulation results which illustrate the performance of efficient wireless power transfer for IoT devices.
