Abstract

MeshTest is a laboratory-based mobile wireless testbed. The system offers more realism than simulation or network-level emulation because it uses real implementation running on real devices, communicating using real wireless hardware over an emulated RF environment. However it also provides repeatability, control, and convenience not possible in field experiments. The original MeshTest system could only accommodate 8-16 nodes in an experiment. The Virtual MeshTest (VMT) system expands the capacity of the system, using virtualization and live migration to facilitate much larger Delay-Tolerant Network (DTN) experiments.
