BAT: Backscatter Anything-to-Tag Communication
- 1.9k Downloads
Computational RFID prototypes are limited by networking abstractions that impose narrow preconceptions about topologies and applications. These prototypes support programmability and integrate a wide array of sensors, which open the door to more varied applications. Implementing these on constrained platforms will need primitives that seamlessly support communication among tags and also with other devices. While overlays on top of existing protocols are possible, they introduce in ef?ciency because of packet formats designed explicitly for the tag inventory paradigm. This paper presents BAT, a networked system designed from the ground up to enable non-supply-chain RFID applications while carefully considering the unique constraints under which these platforms operate.
