Mobile ad-hoc networks (MANETs) are fast growing methods of efficient wireless communications in highly mobile environment. Such networks can be designed using software simulators, that allow users to design, test and analyze new solutions at a low cost. These tools enable also an analysis of network configuration and protocol used for optimizing radio resources and performing the best Quality of Service (throughput, delays, etc.). However the simulators cause approximations of results due to simplification of EM compatibility issues and propagation phenomena in the electromagnetic environment. Furthermore the most common simulators do not allow the simulation in a real time, that causes long simulation. This problem can be solved using real time test beds, containing SDR (Software Defined Radio) base solutions. The most popular device based on this technology is USRP (Universal Soft-ware Radio Peripheral), that is widely used by researchers to study various transmission protocols or create real-time applications like OpenBTS or MIMO links.
