DES-Testbed

The DES-Testbed

The Distributed Embedded Systems Testbed (DES-Testbed) is a hybrid wireless multi-transceiver testbed for long-term studies. It consists of a wireless mesh network (WMN) and a wireless sensor network (WSN). Our hybrid devices are called DES-Nodes. Currently, the testbed consists of 95 wireless mesh routers equipped with three or more IEEE 802.11a/b/g network adapters and the same number of wireless sensor nodes of type MSB-A2. In addition we have a virtualizer running several virtual machines (VMs) that recreate the testbed's topology and its lossy links. Using a custom kernel module in the VMs and a daemon on the virtualizer we can fully emulate the wireless medium.

The research focus of our group is on network architectures, protocols on ISO/OSI layers 2-7, and applications for next generation wireless networks. The DES-Testbed enables to compare simulation studies with real world experiments. To ease the specification, execution, and evaluation of experiments in complex scenarios, we developed serveral frameworks to support our holistic research projects:

DES-SERT: Framework for underlay routing in user space
DES-TBMS: Automated experimentation and evaluation system
DES-Cript: A domain specific language to specify and run experiments
DES-LOFT: Framework for indoor localization and navigation
DES-Vis: Testbed visualization and monitoring

The DES-Testbed is an essential part of ongoing projects such as OPNEX, WISEBED, G-Mesh-Lab, and WiMeshLab.

Presentation of DES-Framework

Posted August 4th, 2010 by Dipl.-Inf. Oliver Hahm

This week we gave a talk about the DES-Framework, our vision of extending the testbed by virtualization and simulation at the 10th Workshop on IP, the EuroView 2010, in Würzburg. An abstract of our tallk and of all other presentations at the conference is available at the EuroView web page.

Our project partner from Lübeck also presented the entire Real-World G-Lab project at the co-located G-Lab Status Meeting.

libdessert 0.95

Posted July 19th, 2010 by Dipl.-Inf. Bastian Blywis

Application:

libdessert

Version:

0.95

libdessert version 0.95 has been released. Actually, we skipped a public release of 0.94, as the only change is mostly relevant for our testbed. Please have a look in the ChangeLog file for a list of all changes.
