Simulating the influence of IVC on road traffic using bidirectionally coupled simulators

We discuss the need for bidirectional coupling of network simulation and road traffic microsimulation for evaluating vehicular ad hoc networks (VANETs) in a simulation framework. As the selection of a mobility model influences the outcome of simulations to a great deal, the use of a representative model is necessary for producing meaningful evaluation results. Based on these observations, we present a hybrid simulation framework composed of the road traffic simulator SUMO and the network simulator OMNeT++. The coupled simulation environment is used for an evaluation of two protocols for incident warning in VANETs.
