Our research interests are pursued within a number of projects, highlighted below. Each project is described in detail on a separate page.
Further we are strongly committed to the exchange of research results, tools and environments. Information is available on the pertaining project pages.
Wireless traffic demand is currently growing exponentially. This growing demand can only be satisfied by increasing the density of points of access and combining different wireless technologies. In this context, CROWD promotes a paradigm shift in the future Internet architecture towards global network cooperation, dynamic network functionality configuration and fine, on demand, capacity tuning. The project targets very dense heterogeneous wireless access networks and integrated wireless-wired backhaul networks.
This is a DFG funded project on reactive construction and reactive routing in euclidean and topological netowrk spanners in wireless ad-hoc and sensor networks.
This is a research project funded by the DFG collaborative research center SFB 901 "On-The-Fly-Computing". The research center investigates individually and automatically configured IT services which are composed from and executed on a marked of world wide traded combinalbe services and execution platforms. Within this research center our research group investigates the the communication network as one important ingredient for such market platform. Our research covers the realization and optimization of overlays over real networks.
The need for structural changes in the Internet is becoming increasingly evident.The SAIL project is taking an evolutionary approach and builds on results of previous projects such as 4WARD to develop the next generation Internet architecture that can better cope with the new challanges such as mobility, heterogenity, and increased information dissemination.
This is a European Union Research Project consisting of 24 project partners.
August 2010 - January 2013.
Communicate Green - IT2Green, BMWi Project. This project, which is carried out together with Deutsche Telekom Laboratories, Ericsson GmbH, Fraunhofer Gesellschaft zur Förderung der angewandten Forschung e.V. and Technische Universität Berlin, focuses on saving energy in modern mobile networks.
Our research group is mainly interested in saving energy in the mobile core network, i.e. all devices that are needed to transport user and signalling data from the radio basestation to its destination.
The goal of the MIKOA project is to develop small and energy self-sufficient sensor nodes for reliable wireless communication in an automation environment. The unique challenges and requirements of the inherently unreliable wireless medium, coupled with delay constraints and error bounds, demand for custom hardware and communication protocols.
Ein extrem verbrauchsarmes, skalierbares, tandemprozessorbasiertes Funksystem für sensorische, aktuatorische und kennzeichnende Anwendungen
An extremly power-efficient, scalable, Tandem-processor-based radio system for sensing and actuation application
Today's network architectures are stifling innovation, restricting it mostly to the application level while the need for structural change is increasingly evident. The absence of adequate facilities to design, optimize, and interoperate new networks currently forces a convergence to an architecture that is suboptimal for many applications and that cannot support innovations within itself, the Internet. 4WARD overcomes this impasse through a set of radical architectural approaches built on strong mobile and wireless background. This is a European Union Research Project consisting of 37 project partners.
January 2008 - June 2010.
The WASP project aims to narrow the gap between research and actual deployment of wireless sensor networks. This was a European Union Research Project with 19 project partners. September 2006 - October 2010.
The objective of this project is to evaluate the performance of typical Wireless Local Area Network (WLAN) systems, e.g. IEEE802.11a, for using it in Wireless Metropolian or Wide Area Networks (WMAN or WAN). This project is a collaboration with the Eggenet GmbH, Paderborn.
