V2X-Enabled Energy-Efficient Transmission in Cellular Networks
In this paper, we propose an energy-efficient vehicle-to-everything (V2X)-enabled transmission scheme in uplink cellular networks. We aim to minimize the uplink energy consumption while considering both circuit power and transmit power. The optimal resource allocation algorithm for direct transmission and V2X-enabled transmission are derived, respectively. The simulation results show that the proposed V2X-enabled transmission scheme can achieve significant energy saving compared with the traditional direct transmission, the decode-and-forward (DF)-based transmission and the opportunistic store-carry and forward (SCF)-based transmission schemes, especially when the cell radius is large.
