With the development of recent vehicular communication technologies, distributing multimedia contents in the Vehicular Communication Networks (VCNs) has become more and more popular, to provide conveniences and entertainment services during the time of driving. However, as multimedia contents are changed and updated dynamically, how to keep the consistency between the original and these replicas in VCNs is very important. Therefore, this paper designs a novel algorithm to control the consistency for the VCNs. In the authors' proposal, after the analyses of the status of road-side units, on-board units and local geographical information, they divide all replicas into different groups, where one is necessary for update and the other are not.
