PEARL: A Novel Priority and Guaranteed-based Resource Allocation Approach for V2V Communications in LTE-V Mode 3

Enabling direct Vehicle-to-Vehicle (V2V) communications within LTE-V technology is considered as a key technological breakthrough to further deploy vehicle-to-Everything (V2X) applications. As the main goal of these latter is to improve the traffic safety and save lives, any design of a resource allocation scheme under LTE-V has to take into account the stringent requirements of these applications in terms of reliability and latency. In this context, this paper proposes a novel Priority and guarantEed-bAsed Resource aLlocation approach (PEARL) for cellular V2V communications under a mode 3 configuration. Extensive simulations and comparison to other approaches corroborate the out-performance of our proposal to deliver emergency packets with lower delays and higher packet reception rate without impacting the transmission of non-safety V2X packets.
