Demo: The acoowee-framework

Abstract

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.

Configuration and operation of networked control systems over heterogeneous WSANs

“…Another recent proposal, the acoowee-project [Fuchs et al 2011], applies UML2 activity diagrams (UADs) for specifying the behavior of the WSN, in order to simplify programming those systems. Acoowee deals with individual WSN nodes, it does not deal with uniform configuration and processing over the NCS that includes WSN subnetworks.…”
