EPSRC Energy Harvesting Network

Columbia University (EnHANTs Project )

In this project we are developing Energy-Harvesting Active Networked Tags (EnHANTs). EnHANTs are small, flexible, and self-reliant (in terms of energy) devices that can be attached to objects that are traditionally not networked (e.g., books, clothing, and produce), thereby providing the infrastructure for various novel tracking applications. Examples of these applications include locating misplaced items, continuous monitoring of objects (items in a store, boxes in transit), and determining locations of disaster survivors.

Recent advances in ultra-low-power wireless communications, ultra-wideband (UWB) circuit design, and organic electronic harvesting techniques will enable the realization of EnHANTs in the near future. In order for EnHANTs to rely on harvested energy, they have to spend significantly less energy than Bluetooth, Zigbee, and IEEE 802.15.4a devices. Moreover, the harvesting components and the ultra-low-power physical layer have special characteristics whose implications on the higher layers have yet to be studied (e.g., when using ultra-low-power circuits, the energy required to receive a bit is an order of magnitude higher than the energy required to transmit a bit).

The objective of the project is to design hardware, algorithms, and software to enable the realization of EnHANTs. This interdisciplinary project includes 5 PIs in the departments of Electrical Engineering and Computer Science at Columbia University with expertise in energy-harvesting devices and techniques, ultra-low power integrated circuits, and energy efficient communications and networking protocols.

Biography
I am a second year PhD student at Columbia University. I received my Bachelor and Master degrees in Electrical Engineering from University of Ottawa, Canada. Prior to joining Columbia's PhD program, I worked as a research scientist at Defence Research and Development Canada (DRDC) and at Telcordia Technologies. At DRDC and Telcordia Technologies my research was mainly focused on security of mobile wireless ad hoc networks. In my PhD research, I am working on developing networking, communication, and energy-management protocols for ultra-low-power energy-harvesting devices.
