Predicting the Performance of Mobile Ad Hoc Networks Using Scaled-Down Replicas

—Experimentation with mobile ad hoc network testbeds is preferred to simulations for performing high fidelity testing. But, at the same time, realistic experimentation with large-scale network testbeds is more difficult, time-consuming, and expensive. To side-step some of these problems several researchers, e.g. [1], [2], have recently suggested experimentation on scaled-down replicas and have managed to downscale some specific indoor network realizations with no mobility. However, the question of whether a scaled-down replica can reproduce the behavior of an arbitrary large-scale mobile ad hoc network, in a timely manner, and under realistic outdoor conditions, remains an interesting open problem. In this work we investigate ways of constructing suitably scaled-down replicas, both in space and time, that can predict the performance of large-scale mobile ad hoc networks with high accuracy. We consider both large- and small-scale fading effects. Further, we present necessary and su...
