wnPUT Testbed Experimentation Framework

In this paper, we present a MANET experimentation framework developed at Poznan University of Technology within the EU FP7 OPNEX project including its main part called the wnPUT testbed. The presentation is complemented by description of the state-of-the art in research on wireless testbed development and experimentation methodology. The main goal of the wnPUT testbed environment is to support the first stage of experimental research on backpressure-based wireless networks. From this perspective, wnPUT is a small-scale testbed with the aim of ‘preliminary' experimentation supporting target activities realized subsequently in large-scale testbed environments. The paper contributes with a description of the testbed development process, tested functionalities, as well as hardware and software characteristics. In particular, we analyze experiment execution phases such as network configuration, node monitoring and results evaluation, as well as a set of methods used to gather and visualize statistics.
