The DES-Testbed (Distributed Embedded Systems) is a hybrid wireless testbed setup for long-term studies. It consists of a wireless mesh network (WMN) and a wireless sensor network (WSN). Both wireless nodes are assembled into one enclosure which we denote as DES-Node. Currently, the testbed consists of 70 wireless mesh routers equipped with three or more IEEE 802.11a/b/g network adapters and an equal number of wireless sensor nodes (MSB-A2).

The research focus of our working group is on various network architectures, protocols, and applications for next generation wireless networks. The DES-Testbed provides us in the research primarily on the experimental comparison of simulations and real world implementations. The DES-Testbed allows to perform wireless network experiments using non-simplistic topologies. For this reason, frameworks dedicated to various research topics and to support the holistic experimentation process have been developed.

• DES-SERT: Routing framework
• DES-TBMS: Automated experimentation and evaluation
• DES-Cript: A domain specific language to define and describe network experiments
• DES-LOFT: Localization framework
• DES-Vis: Testbed visualization and monitoring

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