DES Testbed

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. ...

Dependable Systems

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 simulation and abstract stochastic modelling formalisms.   Ongoing work is coordinated through our Wiki page.

Forschungsforum Öffentliche Sicherheit

Forschungsforum Öffentliche Sicherheit

Jochen Schiller

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.

Indoorlokalisierung

FU Berlin

Prof. Dr. Katinka Wolter

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.

LS²

FU Berlin

Heiko Will

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 evaluates all positions of a playing field in parallel, instead of only randomly selected positions. At the end of a simulation run, the user is able to judge the strengths and weaknesses of the algorithm in ...

Peeroskop project

Peeroskop

Computer Systems and Telematics

Jochen Schiller, Matthias Wählisch

 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

RIOT

Matthias Wählisch

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.

SAFEST Project Group

SAFEST

Jochen Schiller, Matthias Wählisch

This Franco-German project aims at a comprehensive solution to ensure the safety and security of the general public and critical infrastructures. Specifically, SAFEST addresses the problems of crowd control and area surveillance at airports. More information is available on the project homepage.

The overall goal of X-Check (Cross-Check) is to provide improved security for ICT-systems by leveraging data from Internet Exchange Points (IXP). X-Check designs and implements a system for the large-scale detection of (a) known security incidents and (b) novel, unconventional anomalies at central Internet nodes.

"Geogrowd - Creating a Geospatial Knowledge World" aims at establishing a fertile research environment by means of a training network that will promote the GeoWeb 2.0 vision and advance the state of the art in collecting, storing, analyzing, processing, reconciling, and making large amounts of semantically rich user-generated geospatial information available on the Web. Specifically, activities will focus on (i) exploiting user-contributed geospatial data, (ii) Web-geodata management ...

01.09.2010 — 28.02.2013

The objective of SKIMS lies in the design, development and implementation of a cross-layer security system for mobile devices. Detection mechanisms as well as a proactive and reactive defense of attacks are core components of this project. The vision of a digital immune system will be demonstrated in a proof of concept in terms of an extended security application for mobile phones. Analog to a traffic light system, the mobile signals the current level of risk to the user and relaxes the status ...

01.02.2012 — 31.05.2015

The typical task of Wireless Sensor Networks is to gather environmental data with the aim to detect application-relevant events. Such events cover a range of security relevant events from trespassing of restricted areas via critical frequencies arising on bridges through to a harmful movement during a physical rehabilitation. During observation, sensor nodes are collecting a huge amount of data that need to be transferred to a central processor. This procedure is very energy consuming and ...
