The MeshTest testbed is designed to subject wireless devices and protocols to realistic and repeatable mobile scenarios, including multi-hop and disconnected topologies. The testbed makes it possible to efficiently test real implementations of ad-hoc and delay-tolerant routing protocols. With the completion of its mobility control software, the testbed has recently become operational for mobile scenarios. In this paper we report on some of the challenges encountered in building the testbed and implementing the control software, switch calibration, and some basic testbed results. We compare the basic results achieved on the testbed to results from live tests with comparable real systems. Since we first introduced plans for the MeshTest testbed, multiple researchers have expressed an interest in building similar setups. Therefore we believe it is valuable to share our experiences and lessons learned so far in bringing this testbed into operation. Categories and Subject Descriptors C.2....
