Recent advances in radio and processing technology have fuelled increased interest and adoption of localisation systems for both indoor and outdoor applications. Outdoor localisation applications, such as animal or people tracking, typically rely on GPS technology thanks to its high availability and accuracy. However, GPS modules are energy-hungry, which causes quick depletion of battery energy at resource-limited tracking devices. This project addresses the tradeoff between energy consumption and localization performance in a mobile sensor network application. The focus is on augmenting GPS location with more energy-efficient location sensors to bound position estimate uncertainty while GPS is off.
Cow Tracking — Wireless sensor networks can provide farmers with real-time measurements of parameters such as soil moisture, crop health, and animal movement. This data will help inform practices for sustainable agriculture and help farmers to more accurately and effectively control activities such as irrigation, planting, stock movement, and pesticide application. Networks of nodes with both sensors and actuators will eventually not only monitor the agricultural environment but also control it intelligently.
Flying Fox Tracking — A key motivating application for long term tracking is to understand the behaviour of migratory birds. In particular, flying foxes are major cause for disease spread in both Australia and in Southeast Asia. These animals are highly mobile, traveling tens of kilometres in a single night and covering distances in excess of 1000 km with the migratory season. In Australia, flying foxes are responsible for the spread of the Hendra virus, which is lethal to horses and harmful to humans. the processes and dynamics that underpin disease propagation within a group of flying foxes are not well understood, which is the main driver to monitor their movements. CSIRO ICT and ecology researchers are working together on developing a new generation of energy-efficient ICT technologies that can continuously track the position of flying foxes, by incorporating expert knowledge on their movement patterns.
Listening for Frogs — Frog populations are often used as a bioindicator of the health of waterway ecosystems, providing valuable information to water resource managers. With the support of Seqwater, CSIRO researchers are working to develop networks of acoustic sensors that can recognise, record, and ultimately classify frog vocalisations.
