Goodbye, Batteries! Networking Ambient Backscatter Tags
The goal of this project is to network backscatter tags. The key motivation is that backscatter communication decreases the amount of energy required for communication with several orders of magnitude which greatly facilitates the design of battery-free embedded devices (since they then only need very limited energy which in most cases can easily be harvested from the surrounding environment).
We have integrated backscatter tags into existing networks. Towards this end, we have selected the IEEE 802.15.4 standard since it is widely used in the realm of standard-based Internet of Things.
