Designing and implementing a mobile ad hoc network testbed

This paper describes our experience in designing and implementing a mobile ad hoc network testbed. The design goal is high efficiency with low cost. Each node runs both the unicast routing protocol and the multicast routing protocols on a dynamic-on-demand basis, and interfaces seamlessly with the existing Internet infrastructure. The most important feature of this testbed is that it can generate user-defined traces and replay whatever the traces obtained in the recorded packet sequences. Through this function of the testbed, we can conduct more precise and flexible experiments.
