With large coverage area, high data rate, low latency and high spectral efficiency, LTE-V has been considered as a promising communication technology in the vehicular networks. However, as all vehicles share the same wireless resource, in LTE-V, how to design power allocation strategy for each vehicle while motivating other vehicles to forward the data remains challenging. In this paper, we model the data transmission in the uplink scenario of the vehicular network as an equilibrium program with equilibrium constraints (EPEC), where the upper-layer vehicles as receivers (VaRs) provide priced relaying service to vehicle as a transmitter (VaT) in the bottom layer. Observing the prices set by serving VaRs in allocated channels, we adopt multi-level water-filling algorithm at the VaT for power allocation. With joint consideration on the optimal reaction of the VaT and the pricing strategy of other VaRs, each VaR optimizes its setting price by adopting the sub-gradient algorithm such that the equilibrium of the formulated EPEC is finally achieved. Simulation results corroborate our theoretical analysis and demonstrate the performance superiority of our proposal as compared with classic pricing strategies of VaRs. |
