Optimal access mode selection and resource allocation for cellular-VANET heterogeneous networks.

In recent years, the vehicular ad-hoc networks (VANETs) have attracted plenty of attention. However, VANETs can hardly meet surging demands of mobile data. Device-to-device (D2D) communication is regarded as a promising method for providing the reliable connectivity between vehicles. The heterogeneous networks including conventional cellular network and VANETs, where the cellular links and the D2D...
