  One of the applications of vehicular ad-hoc networks is warning message
dissemination among vehicles in dangerous situations to prevent more damage.
The only communication mechanism for message dissemination is multi-hop
broadcast; in which, forwarding a received message have to be regulated using a
scheme regarding the selection of forwarding nodes. When analyzing these
schemes, simulation-based frameworks fail to provide guaranteed analysis
results due to the high level of concurrency in this application. Therefore,
there is a need to use model checking approaches for achieving reliable
results. In this paper, we have developed a framework called VeriVANca, to
provide model checking facilities for the analysis of warning message
dissemination schemes in VANETs. To this end, an actor-based modeling language,
Rebeca, is used which is equipped with a variety of model checking engines. To
illustrate the applicability of VeriVANca, modeling and analysis of two warning
message dissemination schemes are presented. Some scenarios for these schemes
are presented to show that concurrent behaviors of the system components may
cause uncertainty in both behavior and performance which may not be detected by
simulation-based techniques. Furthermore, the scalability of VeriVANca is
examined by analyzing a middle-sized model.
