Poster-Abstract: Programming Wireless Sensor Networks using UML2 Activity Diagrams

I. SUMMARY Wireless Sensor Networks (WSNs) consist of a large amount of sensor nodes (spots). We address the problem of how theses spots can be programmed so that they collaborate to fulfil a common task. The novelty of our work is that we assay how UML2 Activity Diagrams (UADs) can be used and adapted for this purpose. To gain insights, we develop a framework for Sun SPOTs. We design activities with Papyrus UML and transform the resulting XMI output to a data format that can be interpreted by the execution environment we have programmed for our Sun SPOTs. We have extended the expressiveness of UADs by an <>-stereotype. This allows us to describe to which Sun SPOT an activity should be allocated. So we can not only program the behaviour of one Sun SPOT locally, but also the behaviour of the whole network. With this poster we introduce our attempt, the framework, a detailed experiment showing all supported UAD-elements and our preliminary results. Additionally, we give a brief insight in our further work.
