Wireless network testbeds have emerged as a valuable alternative to network simulation, but actually using them for experiments presents a number of challenges. We use the ORBIT testbed at Rutgers University, New Jersey, USA as a case study to illustrate the most important issues in this context. We performed several types of evaluation tests on ORBIT, as well as a series of equivalent experiments with up to 50 nodes, which were done also on the QOMB wireless network emulation testbed, and by

We conclude that a testbed such as ORBIT provides a viable approach to network testing, although this is conditioned by an awareness of the potential pitfalls that may affect experimental results; a series of lessons we learned from our experience is included in the paper. We also show that real-world trials on ORBIT can be broadly reproduced through emulation and even through simulation.
