Adequacy of 5.9 GHz Band for Safety-Critical Operations with DSRC

TL;DR

This paper evaluates the suitability of the 5.9 GHz band for safety-critical V2X communications, proposing a risk-based prioritization method to optimize DSRC network performance amidst recent regulatory changes.

Contribution

It introduces a novel risk-based prioritization scheme for DSRC transmissions to enhance safety-critical communication efficiency in the 5.9 GHz band.

Findings

Mathematical analyses support the prioritization approach.

Numerical results demonstrate improved safety communication performance.

Abstract

The recent reform of the 5.9 GHz by the United States Federal Communications Commission (FCC) provoked the need for lightening the load of a vehicle-to-everything (V2X) communications network based on Dedicated Short Range Communications (DSRC). We have collected mathematical analyses and numerical results supporting our proposal of lightening a DSRC network by prioritizing the transmission based on the risk of accident to which a vehicle is exposed.
