An adaptive testbed of energy harvesting active networked tags (EnHANTS) prototypes

EnHANTs will be small, flexible, and self-powered devices that will be attached to objects that are traditionally not networked (books, furniture, clothing), thereby enabling various tracking applications (more details are available at enhants.ee.columbia.edu). We demonstrate a small testbed of En- HANTs prototypes. The prototypes communicate using in-house-developed ultra-wide-band impulse radio (UWB-IR) transceivers. They create a multihop network and adapt the topology and communication patterns to the light energy harvested by the solar cells. The testbed includes a unique software-based light control system which enables controlled experiments. This demonstration accompanies [3].
