Research paper thumbnail of Protocol design for ultra-low power wake-up systems for tracking bats in the wild

2015 IEEE International Conference on Communications (ICC), 2015

The main application field is monitoring contacts and even tracks of bats in the wild. Our sensor nodes can weigh at most 2 g out of which 1 g remains for the battery. We investigate a novel communication protocol design applicable to these systems and also showing great potentials for other ultralow power sensor networks. In particular, we investigate the bat to ground communication by combining duty cycling with a multistage 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.
