Projects
AVS Extrem
The German Federal Criminal Police Office (BKA) declares in 2006 a 50-percent increase of the thefts of construction sites. The financial loss for landlords and other owners of construction site equipment was estimated with approximately 90 million Euro. Therefore a flexible, spontaneously installable, economical and interface-open monitoring network is necessary. In this project the Freie Universität of Berlin investigates the possibility to establish distributed event detection in wireless ...
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. Members Prof. Dr. Katinka Wolter Michael Bode Alexandra Danilkina Tilman Kraus Qiushi Wang Huaming Wu ...
FOES
As the first nationwide project of its kind, the Research Forum of Public Safety and Security, FOES, is being set up at Freie Universität Berlin. Its objective is to facilitate the permanent exchange of needs, ideas, and suggestions between national and international security research and industry, associations, public institutions, public authorities, and organizations. A key objective is to bring together previous work on public safety from different disciplines to obtain inter- and ...

Flow
Flow is a Software Factory for Wireless Sensors Networks (WSNs). Software Factories are model-driven development environments. Flow allows modeling of applications for WSNs with the help of a visual editor. Flow focuses on data-centric programming. The key component is the concept of a data flow that can be used to describe how data should be processed. Domain experts use a visual Domain-Specific Language (DSL) to define data flows and thus specify the behavior of nodes in the network. With ...
G-Mesh-Lab
This one of the projects that has been founded for the second phase of the G-Lab project (http://www.german-lab.de). The focus of the project is on architectures of heterogeneous wireless networks, like wireless mesh networks, wireless sensor networks, and their role in the Future Internet. Project Page.
Geocrowd
"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 ...

HyperStar
HyperStar is a tool for fitting phase-type distributions to data sets.
LS²
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 ...

OPNEX
OPNEX delivers a first principles approach to the design of architectures and protocols for multi-hop wireless networks. Systems and optimization theory is used as the foundation for algorithms that provably achieve full transport capacity of wireless systems. Subsequently a plan for converting the algorithms termed in abstract network models to protocols and architectures in practical wireless systems is given. Finally a validation methodology through experimental protocol evaluation in ...
Peeroskop
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 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
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.
Leitung: Jochen Schiller, Matthias Wählisch
SKIMS
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 ...

VIVE
![vive 2d_2 [Konvertiert]](/inf/groups/ag-tech/projects/VIVE/vive_2d_2__Konvertiert_.png?1346661223)
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 ...

WISEBED
The aim of this project is to provide a multi-level infrastructure of interconnected testbeds of large-scale wireless sensor networks for research purposes, pursuing an interdisciplinary approach that integrates the aspects of hardware, software, algorithms, and data. This will demonstrate how heterogeneous small-scale devices and testbeds can be brought together to form well-organized, large-scale structures, rather than just some large network; it will allow research not only at a much ...
