The EXC toolkit for real-world experiments with wireless multihop networks

In this paper, we present a methodology and a toolkit to conduct tightly controlled real-world experiments in wireless multihop networks. The main features of our EXC toolkit are a plug-in architecture for easy integration of new functionality, simple scheduling of experiment runs, direct monitoring of experiments, easy management of node mobility, and high portability. EXC does not require specific hardware and can be used for investigating applications and algorithms in real-world environments. We explain the basic features of the toolkit and examine these by means of an experiment with a special focus on repeatability.
