Abstract
We present Koala, a reliable data retrieval system de-
signed to operate at permille (.1%) duty cycles, essential
for long term environmental monitoring networks. Koala
achieves these low duty cycles by letting the network's
nodes sleep most of the time and reviving them through an
efficient wake-up strategy whenever the gateway performs a
