With the increasing demand of communication, it is of great necessity to maximize the utility of vehicular network. VANETs (Vehicular Ad-hoc Networks) especially in the context of high mobility attract more attention all over the world. Pure vehicle-to-vehicle(V2V) networks may relatively have long delay and worse performance compared to vehicle-to-infrastructure(V2I) networks, while V2V networks have larger communication area. Consequently, vehicular network integrated with 3G network is of significance. In these networks, gateways are generally used as interfaces between hybrid networks, thus gateway selection becomes the primary challenge. The most important thing considered in our work is that whenever infrastructures and 3G networks are considered, price is a core problem. The justice of caring the interests of all the vehicle nodes is going to be considered. In this paper, we consider the VANET and 3G connected model under cognitive situations, and then a price based on hierarchical strategy on the cooperative sensing and cluster head selection is proposed to ensure the maximum benefit of both the cluster heads and the cluster members.
