The internet-of-things (IoT) environment connects different intelligentdevices together and enables seamless data communication between the connecteddevices. Connected vehicles (CVs) are one of the primary example of the IoT,and the efficient, reliable, and safe operation of CVs demands a reliablewireless communication system, which can ensure high throughput and lowcommunication latency. The 5G millimeter wave (5G mmWave) wirelesscommunication network offers such benefits, which can be the enabler of CVapplications, especially for dense urban areas with high number of CVs. In thisstudy, we present a simulation-based evaluation framework of end-to-end 5GmmWave communication for CV applications. In addition, we compare the 5G mmWavewith the Dedicated Short Range Communication (DSRC) technology for a CVapplication. The simulation framework is developed using two simulators, anetwork simulator and a traffic simulator. In order to develop the framework inthis study, we have used Network Simulator 3 (ns-3) and SUMO, an open-sourcemicroscopic roadway traffic simulator. We have used end-to-end latency, packetloss and throughput as the performance evaluation metrics. We have found thatfor dense urban areas, 5G mmWave can achieve higher throughput, lower latencyand lower data loss compared to DSRC. 5G mmWave can support CV applicationswith high throughput requirement on the downlink data flow. Through furtherinvestigation, we have found that the performance of 5G mmWave is significantlyimpacted by the penetration level of CVs, maximum CV speed, and CV applicationrequirements.
