Roomba MADNeT: A Mobile Ad-Hoc Delay Tolerant Network Testbed

The authors have built a Mobile, Ad-hoc, Delay tolerant, Network Testbed (MADNeT). Their testbed is geared towards enabling the exploration of highly disconnected networks whose nodes must store and forward information (multi-hop paths are very unlikely), while allowing one to explore connected network scenarios as well. Using their MADNeT, they can emulate a wide range of mobile networking scenarios and execute real-world (albeit somewhat simplified) data collection missions. Their system is built from Commercial Off-The-Shelf (COTS) hardware running a paired-down Linux OS, yielding a relatively inexpensive, but fairly flexible mobile network testbed.
