DSRC versus 4G-LTE for Connected Vehicle Applications: A Study on Field Experiments of Vehicular Communication Performance

Abstract

Dedicated short-range communication (DSRC) and 4G-LTE are two widely used candidate schemes for Connected Vehicle (CV) applications. It is thus of great necessity to compare these two most viable communication standards and clarify which one can meet the requirements of most V2X scenarios with respect to road safety, traffic efficiency, and infotainment. To the best of our knowledge, almost all the existing studies on comparing the feasibility of DRSC or LTE in V2X applications use software-based simulations, which may not represent realistic constraints. In this paper, a Connected Vehicle test-bed is established, which integrates the DSRC roadside units, 4G-LTE cellular communication stations, and vehicular on-board terminals. Three Connected Vehicle application scenarios are set as Collision Avoidance, Traffic Text Message Broadcast, and Multimedia File Download, respectively. A software tool is developed to record GPS positions/velocities of the test vehicles and record certain wireless communication performance indicators. The experiments have been carried out under different conditions. According to our results, 4G-LTE is more preferred for the nonsafety applications, such as traffic information transmission, file download, or Internet accessing, which does not necessarily require the high-speed real-time communication, while for the safety applications, such as Collision Avoidance or electronic traffic sign, DSRC outperforms the 4G-LTE.

“…where (a) follows the Leibniz-Newton formula, (b) follows from (9), and (c) follows from the the fact that M i 2 M j 2 = 0 when j = i − 1. To find the value of the threshold τ max , we use the following candidate Lyapunov function [46]: V (e) = e T P e, where P = I 2M ×2M .…”

Early Findings from Field Trials of Heavy-Duty Truck Connected Eco-Driving System

“…Although short-range communication technology such as DSRC is widely used by various CAV applications, their low scalability and asynchronous disadvantage may lead to several issues. As a substitute, 4G-LTE has been adopted to enhance V2N and I2N communications given its versatile communications types from one-to-one to one-to-multiple transmissions, with both simulations and field experiments conducted by researchers all over the world during the past decade [16], [17]. In our connected eco-driving system, we also install a 4G-LTE cellular module with AT&T SIM card on board to enable V2N communication.…”

“…Numerous comparisons were made regarding LTE and DSRC based connectivity for ITS and taking vehicular networking into a new level of utilizing LTE due to its potential benefits. It is mentioned and justified in the previous study that the combination of LTE and DSRC ought to be a decent solution for connected vehicles for diverse safety and nonsafety applications. It will not just empower safe driving yet in addition can give top notch telematics administrations to clients.…”
