Category: Modelling and Analysis

Large scale distributed defence systems have specific environmental considerations that must be taken into account in their design, for example restrictions on space, weight and power (SWaP), real-time performance constraints, and the need for long life spans. In this work, we explore the development of performance modelling, prediction and evaluation environments that support the analysis of the performance considerations of distributed systems in relation to their environment.

We have constructed a performance modelling environment, MEDEA, which supports modelling of complex software system performance above realistic deployment scenarios, including defence standard hardware, middleware and OS environments. In our research, we develop performance analysis frameworks and tools that support interactive performance analysis in relation to environmental concerns, such as assessing the impact of a potential deployment change (I.e. change to hardware, component location, etc) on SWaP, or real-time performance.

Research Grant: Drones for Good: Airborne spatial tracking for saving endangered species. D. Ranasinghe, L. P. Koh, K. Falkner, B. Ostendorf, G. Puddy, ARC Linkage Project ($181,194) (2016-2018)

This project aims to develop an automated and distributed spatial tracking approach using low cost Unmanned Aerial Vehicles (UAVs) to locate and study endangered wildlife. Understanding animal behaviour and habits with granular spatial data is essential to develop effective monitoring and conservation strategies. Spatial tracking of radio collared wildlife using radio telemetry is a critical […]
