"A Framework for Connectivity Monitoring in Wireless Sensor Networks";
Report No. TUW-241107,
We present an overview of the features and the architecture of a framework for long-term monitoring of the communication topology of a synchronous wireless sensor network. Our framework, a prototype of which has been implemented for Atmel RZ200 motes running TinyOS, locally records the complete connectivity information for every node
in every round, and disseminates this information to one or more root nodes that act as data sinks for monitoring information. Postprocessing tools allow to query the recorded communication graphs, in order to e.g.\ verify structural properties like the presence of multiple strongly connected components. We demonstrate the utility of our framework by means of an experimental evaluation
of the coverage of a recently introduced adversarial network model
for directed dynamic networks. Our measurement results reveal that it has a very good coverage in several small-scale WSN deployments.
