With the DES testbed (Distributed Embedded Systems) we aspire to create a hybrid wireless testbed setup for long-term observations. In a first setup phase at least 50 wireless mesh routers equipped with three or more IEEE 802.11b/g NICs and an equal amount of wireless sensor nodes will be deployed. 100 nodes are planned in the final setup phase. This will enable us do experiments using non-simplistic topologies. The continuous runtime of single experiments is targeted at up to several months. The DES testbed is an essential part of further ongoing projects at Freie Universität Berlin such as OPNEX and WISEBED. A website for the DES testbed is available here .
Welcome at the Dependable Systems Group We work on the measurement, modelling and evaluation of dependable systems. Particular focus areas are service-oriented architectures and Cloud Computing, wireless networks, and mobile telephony. We employ measurement techniques as well as discrete-event ...
Forschungsforum Öffentliche Sicherheit
The Research Forum on Public Safety and Security started in October 2009. It aims at merging research projects and work of different disciplines and institutions that deal with “Public safety and security”. Inter- and transdisciplinary evaluations of the subject will be developed, which will generate recommended procedures for policy, economy and science . Further information.

Unter Indoorlokalisierung versteht man die Ortung von Personen und Objekten innerhalb von Gebäuden. Während außerhalb geschlossener Räume GNS Systeme wie GPS bereits fest in den Alltag integriert sind, stellt die Ortung in geschlossenen Räumen eine Vielzahl neuer technischer und logistischer Herausforderungen dar. Im Fokus unserer Arbeit steht die distanzbasierte Lokalisierung in drahtlosen Netzwerken.
We introduce a simulation engine to visually evaluate and compare distance based lateration algorithms and deployments called the FU Berlin Parallel Lateration-Algorithm Simulation and Visualization Engine (LS²}. Our engine simulates a scenario which consists of given anchor positions and ...

The objective of the Peeroskop project is the design and development of a system for the observational analysis of the Internet part's relevant for Germany, as well as the proactive and reactive protection of the backbone routing. Core components of the project are mechanisms for information fusion and information classification based on passive and active measurements which discover vulnerabilities in the Internet peering beforehand and bypass emerging disruptions.

RIOT is a microkernel based architecture for distributed embedded systems with a strong focus on the Internet of Things and Wireless Sensor Networks. The kernel is real-time capable and supports full multi-threading. Furthermore, it provides mutexes as well as synchronous and asynchronous message passing for interprocess communication. The scheduler is priorty-based and uses a tickless timer system.
