The OMNeT++ simulator is well-suited for the simulation of randomized userbehavior in communication networks. However, there are scenarios, where such arandom model is unsuited to evaluate a communication system, and this paperattempts to highlight such a case. Using this example of ad-hoc communicationbetween aircraft mid-flight, a tutorial-style description is attempted thatshall show how the OMNeT++ simulator can be used when a wealth of real-worldtrace data is available. In particular, it is described how mobility tracefiles can be directly used within OMNeT++, and how to link the generation ofdata messages to this mobility data. This is explained via an examplesimulation that evaluates a communication network in which an aircraft notifiesthe ground control when it enters or leaves a specific geographic region.Additionally, a novel trace-based application has been developed to achievethis link between mobility and message generation. Furthermore, a newTDMA-based medium access protocol for decentralized communication networks ispresented, which is oracle-based and thus allows a TDMA-like behavior of mediumaccess without causing any overhead; it can be useful when upper-layerprotocols should be evaluated under the assumption of TDMA-like behavior, butisolated from the effects of a full-fledged TDMA protocol. Finally, physicallayer behavior is often either overly simplistic or overly computationallyexpensive. For the latter case, when a detailed channel model is available butits evaluation requires prohibitive computational effort, then averaging itsbehavior into trace data can find a middle ground between efficient evaluationand realistic representation. Hence, a novel trace-based radio model has beendeveloped that makes use of an SNR to PER mapping. In the spirit of openscience, all implementations have been made available under open licenses.
