Projects
G-Mesh-Lab
This project is funded by the German Federal Ministry of Education and Research (BMBF) and runs for three years. It is one of the projects that has been funded for the second phase of the G-Lab project (http://www.german-lab.de/) for the Real-World G-Lab (http://www.rwglab.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.

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 real network test-beds is proposed.

WiSEBED
The aim of this project is to provide a multi-level infrastracture 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 larger scale, but also in different quality, due to heterogeneous structure and the ability to deal with dynamic scenarios, both in membership and location.

TCP-Proxy
Wireless networks deviate from wired ones in many properties. The bit-error rate is a magnitude higher, the medium is shared by many entities, and the data rate is lower, to name a few. The Transmission Control Protocol (TCP) has been designed with fast, low bit-error rate networks in mind. Many of the TCP variants, often called "flavors", adapted TCP to networks with a high bandwidth-delay product. These modifications try to keep the virtual channel filled at all times with the maximum number of segments in flight. Coping with the high delays is the focus of research. In contrast, wireless networks exhibit much higher error rates and often times mobile network entities.
