Due to the fact that the MAC layer of commodity 802.11 wire-less network devices is usually realized in a proprietary firmware module, it is difficult to conduct real world evaluations of novel MANET cross-layer protocols that require a modified MAC layer. We demonstrate a testbed framework based on ESB sensor nodes. Due to their open firmware these nodes allow for the implementation of arbitrary MAC modifications and cross-layer interactions. This provides an opportunity to test MANET and Mesh network protocols with this kind of modifications in the real world on commercially available hardware. Our framework contains utilities and modules which automatically detect the network topology for a given node placement, construct and deploy static routing tables along predefined paths and allow an analysis of the network traffic by logging the packet transmissions. The demo points out the feasibility of experiments and cross-layer implementations with our framework on the ESB nodes.
