### Abstract

We present a novel concept for a wake-up system based ultra-low power communication protocol for sensor net- works. The main application field is monitoring contacts and even tracks of bats in the wild. Our sensor nodes can weigh at most 2g out of which 1g remains for the battery. We investigate a novel communication protocol design applicable to these systems and also showing great potentials for other ultra- low power sensor networks. In particular, we investigate the bat to ground communication by combining duty cycling with a multi-stage wake-up receiver. We employ Binary Offset Carrier (BOC) modulated signals that allow to accurately localize and track the bats while transmitting data in parallel. In a first step, we evaluated the conceptual design using a software-defined radio system to demonstrate the feasibility of the protocol design.
