BTnodes- Applications and Architecture Compared (2009)
Jan Beutel, Oliver Kasten, Matthias Ringwald
We motivate a prototyping platform for ad-hoc networking research showing some requirements and constraints. The architecture of the BTnodes, each of which can store information, compute and...
Poster Abstract: Next-Generation Prototyping of Sensor Networks (2009)
Jan Beutel, Matthias Dyer, Martin Hinz, Lennart Meier, Matthias Ringwald
Large-scale deployment of sensor networks is more and more becoming an issue to researchers and industry alike. The recently revised BTnode architecture provides two wireless radios and facilitates...

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...

We motivate a prototyping platform for ad-hoc networking research showing some requirements and constraints. The architecture of the BTnodes, each of which can store information, compute and...
Abstract. This paper describes a way for using a PDA to easily control everyday devices found in our environment. By attaching a laser pointer to the PDA, the user can simply point to a device in...
Demo abstract: Passive inspection of deployed sensor networks with snif (2007)
Matthias Ringwald, Marc Cortesi, Kay Römer
Abstract — We demonstrate a tool that allows inspection and debugging of deployed wireless sensor networks (WSN) by analyzing overheard radio messages. This tool can identify common problems such...
SNIF: Sensor Network Inspection Framework (2006)
Abstract — Recent experience with the deployment of sensor networks demonstrates that it is far from trivial to setup a working larger-scale sensor network in the field. Even though simulations and...
Monitoring and Debugging of Deployed Sensor Networks (2005)
this paper was supported (in part) by the National Competence Center in Research on Mobile Information and Communication Systems (NCCR-MICS), a center supported by the Swiss National Science...
Intrusion Detection and Failure Recovery in Sensor Nodes (2005)
Harald Vogt, Matthias Ringwald, Mario Strasser
this paper, we sketch a system for detecting intrusions and recovering sensor nodes. We plan to come up with an approach for application-based anomaly specification and detection and node recovery,...
