The EXC project provides a toolset for supporting the real-world evaluation of wireless multihop networks. The central component is EXC , the 'wireless multihop network EXperiment Control'. This is a lighweight control software that allows to steer and supervize experiments with wireless multi-hop networks such as MANETs, VANETs or mesh networks. A detailed description can be found in the paper The EXC Toolkit for Real-World Experiments with Wireless Multihop Networks.
DescriptionCurrently, the evaluation of wireless multihop networks (WMNs) is mainly based on simulation. It has been shown that present simulators sometimes exhibit behaviour different from real networks. Therefore it is necessary to conduct real experiments. These experiments take place in a challenging environment and not many experiments with WMNs have been performed up to now. Furthermore, there are only few tools available to support these experiments. The creation of supporting tools and the development of an accompanying methodology is the primary goal of the EXC project.
EXC is currently under active development, a first version has been demonstrated at MobiSys'07 and a corresponding paper has been presented at EXPONWIRELESS'08. It is in active use in several projects of our research group and has been tested in experiments with up to ten static and five mobile, wireless nodes. It runs under Linux, both on notebooks as well as on ARM based Zaurus SL-6000 PDAs.
The tool has been used to examine the topological repeatability of experiments with wireless multihop networks (presented at MSWiM'08). The most recent experiments with EXC have been performed in the context of vehicular ad-hoc networking (VANETs), a paper thereon has been presented at VANET'09.
