Workshop 19: Battery-Free Internet of Things
Title: Backscatter Communications for the Battery-Free Internet of Things
Keywords: Backscatter communications, low-power communications, battery-free IoT.
Summary: The rapid growth of the Internet of Things (IoT) driven by recent advancements in consumer electronics, the fifth generation (5G) and beyond communications cloud-computing-enabled big data analytics has recently attracted tremendous attention from both the industry and academia. One of the significant open challenges for IoT is the limited network lifetime due to massive IoT devices powered by batteries with finite capacities. Although wireless energy harvesting has been proposed to power the IoT devices, the conventional radio architecture of IoT nodes comprises power-hungry RF chains, e.g., oscillators, mixers, and digital-to-analog converters, which can hardly be supported by the energy from wireless energy harvesting alone. Backscatter communications (BackComs), which rely on passive reflection and modulation of an incident radio-frequency (RF) wave, have emerged as a promising solution for energy-constrained IoT devices. However, the contemporary BackCom has several major limitations, such as short transmission range and low data rate. Although these limitations have been tackled in the recently proposed bistatic BackComs and ambient BackComs, the associated signal modulation, interference cancellation, and resource scheduling aspects have not been sufficiently studied. The observation of the recent surge in relevant research and the emergence of many exciting opportunities motivates us to propose the hot feature topic of “Backscatter Communications for the Battery-Free Internet of Things” for this Workshop. Thereby, we seek to bring together researchers from both academia and industry to introduce to the latest advancements in BackComs and and discuss future research opportunities.
