Laboratory-based mobile wireless testbeds such as MeshTest and the CMU Wireless Emulator are powerful platforms that allow users to perform controlled, repeatable, mobile wireless experiments in the lab. Unfortunately such systems can only accommodate 10-15 nodes in an experiment. The authors have designed and built a scalable wireless testbed that uses software virtualization and live migration to facilitate experiments involving intermittently connected networks with many multiples of the number of physical nodes available on such a testbed. In this paper, the authors share their experience with using real traces from the DieselNet/DOME project on their testbed. While this trace provide GPS coordinates for where the contact occurs, they needed to deduce the overall mobility from using GPS logs for individual buses.
