In this paper, we illustrate a Mobile Wireless Vehicular Environment Simulation (MoVES) framework for the parallel and distributed simulation of vehicular wireless ad hoc networks (VANETs).
This testbed, which was named V-MAN (vehicular environment simulation with Matlab and NS2), has successfully finished three simulation works [17, 18] in VANETs for our team.
There are many examples of work using vehicular network simulation to test the applications of wireless technology.
The authors work motivates the need for accurate human-behaviour modelling in vehicular network simulation and what impact the social aspects of mobility provide.
We assess the reliability of our proposal using both realistic crash tests, held in the facilities of Applus+ IDIADA in Tarragona, Spain, and Vehicular Network simulations, based on the ns-2 simulation tool.
For IEEE 802.11p-based vehicular network simulations, the communication range is set to 250 m (or 25 dBm) with parameter values of EnergyDetectionThreshold and CCAModelThreshold set to -83 and -86 dBm, respectively.
The Kuhn-Munkres algorithm is applied to solve the problem of maximum weighted matching of the constructed bipartite graph of the vehicular networks, and simulations indicate that the proposed solution performs extremely close to the optimal one and achieves better fairness.
We have developed an NS-2 model to enable the use of real vehicular traces for realistic simulation study and to support detail simulation of radio propagation and link layer behaviors such as link-layer retransmissions.
One of the most important aspects to evaluate vehicular networks performance via simulation is to use an adequate channel model.
