Parallel and distributed simulation of wireless vehicular ad hoc networks

In this paper, we present a novel solution for the fine-grained parallel and distributed simulation of Vehicular ad hoc networks' (VANETs) services and applications, based on vehicular traffic mobility and wireless IEEE 802.11-standard models. A Mobile Wireless Vehicular Environment Simulation (MoVES) framework supports dynamic partition of geographic areas and dynamic entity mapping of the modeled scenarios over parallel and distributed simulation platforms. This could be a viable solution to enhance simulation performances and to exploit low-cost commercial-off-the-shelf (COTS) simulation architectures. Testbed performance evaluation for realistic modeled scenarios has shown the effectiveness of our approach in terms of simulation efficiency (speedup), and simulation accuracy, also providing guidelines for future enhancements of the framework performances, and model characterization of inter-vehicular communication.
