DSRC Versus LTE-V2X: Empirical Performance Analysis of Direct Vehicular Communication Technologies

Vehicle-to-Vehicle (V2V) communication systems have an eminence potential to improve road safety and optimize traffic flow by broadcasting Basic Safety Messages (BSMs). Dedicated Short-Range Communication (DSRC) LTE Vehicle-to-Everything (V2X) are two candidate technologies enable V2V communication. DSRC relies on the IEEE 802.11p standard for its PHY MAC layer while LTE-V2X is based 3GPP’s Release 14 operates in a distributed manner absence of cellular infrastructure. There has been considerable debate over relative advantages disadvantages LTE-V2X, aiming answer fundamental question which technology most effective real-world scenarios various efficiency applications. In this paper, we present comprehensive survey these (i.e., LTE-V2X) related works. More specifically, study both compare performance using variety field tests. First, provide summary each highlight limitations supporting V2X Then, examine their different metrics.
