The OMNeT++ simulator is well-suited for the simulation of randomized user\nbehavior in communication networks. However, there are scenarios, where such a\nrandom model is unsuited to evaluate a communication system, and this paper\nattempts to highlight such a case. Using this example of ad-hoc communication\nbetween aircraft mid-flight, a tutorial-style description is attempted that\nshall show how the OMNeT++ simulator can be used when a wealth of real-world\ntrace data is available. In particular, it is described how mobility trace\nfiles can be directly used within OMNeT++, and how to link the generation of\ndata messages to this mobility data. This is explained via an example\nsimulation that evaluates a communication network in which an aircraft notifies\nthe ground control when it enters or leaves a specific geographic region.\nAdditionally, a novel trace-based application has been developed to achieve\nthis link between mobility and message generation. Furthermore, a new\nTDMA-based medium access protocol for decentralized communication networks is\npresented, which is oracle-based and thus allows a TDMA-like behavior of medium\naccess without causing any overhead; it can be useful when upper-layer\nprotocols should be evaluated under the assumption of TDMA-like behavior, but\nisolated from the effects of a full-fledged TDMA protocol. Finally, physical\nlayer behavior is often either overly simplistic or overly computationally\nexpensive. For the latter case, when a detailed channel model is available but\nits evaluation requires prohibitive computational effort, then averaging its\nbehavior into trace data can find a middle ground between efficient evaluation\nand realistic representation. Hence, a novel trace-based radio model has been\ndeveloped that makes use of an SNR to PER mapping. In the spirit of open\nscience, all implementations have been made available under open licenses.\n
