The subject is presented by lecturers from the CSIRO ICT Centre who are specialist researchers in this field. It will cover fundamentals of sensor networks as well as advanced topics such as synchronizaton, localization, in-network processing, sensor fusion, security and privacy. A major component of the subject will be an assignment to develop a practical sensor network.

However these control mechanisms incur communication and processing overhead that does not scale well for large or dense networks. Instead, we propose a simple combination of directed broadcast and neighbour message overhearing which is more suitable for such networks. This work is published in the December 2009 issue of the journal ACM Transactions on Sensor Networks.

His paper presents a method for automatically calibrating wireless camera nodes; an ability which is critical to the feasibility of deploying networks consisting of large quantities of these types of devices. The method involves capturing images as the camera is rotated, and computing the homographies between the images in order to determine camera parameters such as the focal length and principal point.

This is the robot's equivalent of you being left blindfolded in an unknown location within a city and looking around to determine where you are so that you can find your way home. The technology can also be used to efficiently determine if a loop has been closed while incrementally building a map, or to merge maps generated at different times or by multiple vehicles.

They also show promise as a computational technique for technical applications such as time series prediction, however they suffer significant variation in performance when applied to different problems and require the development of problem-specific optimisation procedures. We have investigated methods for addressing this issue in collaboration with researchers in Japan and Taiwan, and our findings have recently been published in the Human Frontier Science Program Journal. Our results have both potential for improving engineering applications, as well as implications for understanding how biological neural networks are shaped to be optimally adapted to the requirements of their environment.

This novel animal modelling methodology can successfully recognise and model each individual animal, as well as their herding behaviour. It not only shows that cattle graze pastures in a non-homogeneous way but also begins to identify some of the underlying processes that lead to uneven grazing pressure. Understanding herbivore landscape grazing interactions can lead to improved management intervention strategies such as identifying the optimal location of watering points to prevent localised overgrazing effects.

Flight trials also demonstrated various failsafe modes such as automatic return on loss of communications and in the event that the UAV finds itself "out of bounds" (ie. outside a pre-defined mission boundary). This is a significant milestone in the development of a dependable autonomous helicopter. ARCAA (the Australian Research Centre for Aerospace Automation) is a joint venture of CSIRO and Queensland University of Technology.

This project is a collaboration between CSIRO, Seqwater and the University of Queensland, and involves a deployment of floating sensor nodes, land-based nodes, and an autonomous boat. The system monitors processes that affect water quality and provides this information to operators and modelers to allow early warning of deteriorating water quality.

Whereas most current navigation algorithms in mobile robotics produce 2D maps from data provided by 2D sensors, we have developed a novel algorithm for efficiently constructing 3D maps. Using this technique we mapped a 200 square meter office environment in 3D at 0.02m resolution and demonstrated that a robotic vehicle with only a 2GHz processor and no prior knowledge of its position could locate itself within 5 seconds.
