Measurement-based modeling of inter-arrivals for the simulation of highway vehicular networks

Simulation is the standard approach to the perfor- mance evaluation of vehicular network solutions. However, the relevance of its results is often questioned by the adoption of unrealistic vehicular mobility representations. In this letter, we propose a measurement-based hidden Markov model that gener- ates realistic synthetic interarrivals. The proposed methodology accurately captures important traffic dynamics and provides a reliable input for the simulation of highway vehicular networks.
