Introduction
The most commonly used technique to evaluate novel solutions is to leverage on simulation studies which are largely based on a simplified model of the system behavior. Such an approach provides an approximate evaluation of the system’s performances, which can be potentially far away from the behavior on a real deployment. Another solution is to exploit real world prototypes and testbeds. Such testbeds are generally based on a limited number of nodes and, due to their experimental purposes, they only partially present the challenges of a real operational environment with hundred or thousand users. Furthermore, the limited number of nodes limits the possibility to study scalability issues.
In this paper a novel architectural framework and its implementation are proposed in order to provide a realistic environment where innovative techniques for multi-hop wireless networks can be tested in a controlled environment. The objective of the proposed solution is to depart from the limitations of simulated or real world testbed, while providing a testing environment which facilitates performing experimental studies of real network nodes firmware at large scale. To this purpose VINI (VIrtual Network Infrastructure) [1], an extension of Planet- Lab – a planetary distributed testbed composed of thousand of nodes, has been selected as the basis for the proposed framework.
