Today I will introduce Flow. With Flow you can model the behavior of nodes in a wireless sensor network (WSN) in a data driven and event driven manor. I developed Flow as part of my diploma thesis.

Flow is build as a Visual Studio Addon (a VS Package) on top of the DSL-Tools containing three different domain specific languages to describe different parts of the software running on a sensor node. These different DSLs are working together and using most of the techniques I described earlier in this blog. E.g. my library JaDAL was initially build to support this diploma thesis.

You will find screenshots, more explanations and Flow itself on http://flow.irgendwie.net. While the webpage and the software are available in English the thesis itself is a pdf-document and can only be downloaded in a German version.

The software is fully working and if no wireless sensor network is available you can use a node simulator to evaluate Flow. The code is released under the new BSD license and also available for download.

Dataflows modeled with Flow looks like that:

The simulated sensor nodes are represented as Windows forms programmed by such dataflows:
