Title: Assessing dependability of mobile computing systems
Mobile application offloading moves compute intensive jobs from energy-constrained mobile devices to powerful servers or the Cloud. The decision when and what to offload depends on many factors. Next to the obvious ones, the application and network connectivity, it also depends on the metrics of interest. I will show how to balance energy concerns with response time requirements. Even with the same attributes the formulation of the trade-off between them has an impact on the decisions taken based on the metric. I will talk about how to investigate trade-offs in the setting of mobile offloading.
Prof Wolter is Professor at Freie Universität Berlin. She is the head of the Dependable Systems Group. Their field of research is adaptive and resilient distributed computing systems using stochastic models and online versions of machine learning techniques. She is interested in measuring and evaluating dependability, performance, and security of complex computing systems, with a particular focus on timing behaviour. Within their group they employ a broad range of assessment and evaluation techniques for computing systems and networks, ranging from fault-injection test-beds to simulation and analytical techniques. They develop efficient and accurate modelling and evaluation techniques, applying e.g. Phase-Type distributions in fault-modelling for fault-injection experiments and hybrid discrete-event simulation. They study a large variety of systems, including wireless networks, mobile telephony networks, service-oriented systems, and Computing Clouds.
