Robust and reliable wireless communication is one of the most important requirements in many application domains. This includes industrial networks, health care applications, as well as Vehicular Ad Hoc Networks where safety applications are seen as a main driver for their introduction. However, due to highly dynamic network structures and rapidly varying channels these networks are particularly challenging from a communications perspective.
In the context of the Wime Project, we work on Open Source tools that help in gaining a deeper understanding of wireless networks. The tools are based on GNU Radio, a well-know real-time signal processing framework for use in Software Defined Radio (SDR) systems. Using SDR we are able inspect, change, and experiment with every aspect of the communication system. By implementing everything on a normal PC, our system lends itself well for rapid prototyping and allows using the same code for simulations as well as over-the-air experiments, offering a seamless switch from theory to practice.
WiFi networks, which are already ubiquitous today, will soon spread even further by providing the base for inter-vehicular communication systems. To study these networks, we provide a complete physical layer implementation, including a tool chain for simulation and experimentation.

Energy-efficient wireless networks have many important applications in health care, industrial automation, and form the base for an Internet of Things. We provide a complete IEEE 802.15.4 stack that is interoperable with the ContikiOS up to the network layer.
