Abstract
Vehicle-to-vehicle (V2V) communication which supports ubiquitous information exchange and content sharing among vehicles with little or no human intervention becomes a key enabler for intelligent transportation industry. In this paper, we adopt a two-hop relay transmission mode to maximize the total spectrum efficiency of a device-to-device (D2D) based vehicular cooperative network while ensuring the quality of service (QoS) provisions of both V2V links and cellular links. We propose an auction-matching based joint relay selection and spectrum allocation algorithm, which solves the matching problem among D2D-V2V pairs, relay stations and resource blocks in an iterative fashion with English-auction based preference updating and conflict avoidance. Finally, the spectrum efficiency and convergence performances are evaluated based on real-world map and realistic vehicular traffic by connecting SUMO with MATLAB through TraCI4MATLAB.
