Increasing the visibility of sensor networks with passive distributed assertions (2010)
When deployed in a real-world setting, many sensor networks fail to meet application requirements even though they have been tested in the lab prior to deployment. Hence, concepts and tools for...
Deployment Techniques for Sensor Networks ⋆ (2010)
Jan Beutel, Kay Römer, Matthias Ringwald, Matthias Woehrle
Abstract. The prominent visions of wireless sensor networks that appeared about a decade ago have spurred enormous efforts in research and development of this new class of wireless networked embedded...
BTnodes- Applications and Architecture Compared (2009)
Jan Beutel, Oliver Kasten, Matthias Ringwald

Passive Inspection of Sensor Networks (2008)
Matthias Ringwald, Kay Römer, Andrea Vitaletti
Abstract. Deployment of sensor networks in real-world settings is a labor-intensive and cumbersome task: environmental influences often trigger problems that are difficult to track down due to...
Abstract — Many sensor network applications feature bursty traffic patterns: after long periods of idle time with almost no network traffic, large amounts of data have to be transmitted reliably...
We demonstrate a tool to inspect nodes of a deployed wireless sensor network (WSN) in the field. While an operational WSN can be remotely monitored via multi-hop routing, a newly deployed network...
