Abstract

Pervasive systems enhance our environment with various services under a wide range of contextual conditions. Hence, as a user's context may change over time, pervasive systems shall be able to reconfigure themselves. While such reconfigurations are typically difficult to conceive, a system designer might be interested in their triggers and execution. To this end, we demonstrate Coalaviz, a tool for making adaptation decisions in pervasive communication systems traceable. Our demonstration shows the capabilities of Coalaviz based on the Tasklet system, a distributed computing system for task offloading. The offloading mechanism can be reconfigured in terms of the scheduling strategy. We show the use of Coalaviz and how the Tasklet system behaves in different contextual situations and during reconfigurations based on changing goals.
