Demo: The acoowee-framework

Within the framework of the acoowee-project we want to improve the programming of Wireless Sensor Networks (WSNs) by using and adapting the expressiveness of UML2 Activity Diagrams (UADs) to specify the behavior of the WSN. We expect that our proposal can simplify the way of programming the functional behavior of a WSN and so bring the programming closer to domain experts. We develop the acoowee-framework for Sun SPOTs (spots). The user of the acoowee-framework visually programs UADs and saves them. Afterwards, these UADs are converted into scripts and deployed to the spots e.g. over the air. Finally, the interpreter that runs on the spots executes the scripts. In this demo we present the usage of the acoowee-framework by means of a network consisting of 5 spots and a host with a connected base station. We present all steps listed above. Additionally, we show a rule based manipulation of already deployed scripts and give the attendees the possibilities to try this kind of programming by themselves.
