TLDR
Standards and weaknesses of LTE as an enabling technology for vehicular communications are analyzed, and open issues and critical design choices are highlighted to serve as guidelines for future research in this hot topic.Abstract:
A wide variety of applications for road safety and traffic efficiency are intended to answer the urgent call for smarter, greener, and safer mobility. Although IEEE 802.11p is considered the de facto standard for on-the-road communications, stakeholders have recently started to investigate the usability of LTE to support vehicular applications. In this article, related work and running standardization activities are scanned and critically discussed; strengths and weaknesses of LTE as an enabling technology for vehicular communications are analyzed; and open issues and critical design choices are highlighted to serve as guidelines for future research in this hot topic.read more

Proactive Doppler Shift Compensation in Vehicular Cyber-Physical Systems
TL;DR: In this article, a proactive Doppler shift compensation algorithm based on the probabilistic graphical model is proposed for vehicular cyber-physical systems (CPS), where each vehicle pre-compensates its carrier frequency individually, so that there is no frequency shift from the desired carrier frequency between each pair of transceiver.

Performance Analysis of Cellular-Relay Vehicle-to-Vehicle Communications
TL;DR: This study theoretically analyze the performance of cellular-relay (CR) V2V communications, in which a vehicle first transmits a message to its nearest BS via uplink, and then, the BS forwards the message to a destination vehicle via downlink.

Enhancing IEEE 802.11p/WAVE to provide infotainment applications in VANETs
TL;DR: The proposed W-HCF (WAVE-based Hybrid Coordination Function) protocol leverages controlled access capabilities on top of the basic contention-based access of the IEEE 802.11p; it exploits vehicles' position information and coordination among WAVE providers in order to improve performances of delay-constrained and loss-sensitive non-safety applications.
