Operating ITS-G5 DSRC over Licensed and Unlicensed Bands: A City-Scale Performance Evaluation

Dataset

Description

A large-scale dataset of measurements of ETSI ITS-G5 Dedicated Short Range Communications (DSRC) is presented. Our dataset consists of network interactions happening between two On-Board Units (OBUs) and four Road Side Units (RSUs). Each OBU was fitted onto a vehicle. The two vehicles have been driven across the Innovate UK-funded FLOURISH Test Track encompassing key roads in the center of Bristol, UK. As for the RSUs, they were located at fixed locations around the track. Each RSU and OBU is equipped with two transceivers operating at different frequencies. During our experiments, each transceiver broadcast Cooperative Awareness Messages (CAMs) every 10ms to the neighboring RSUs and or OBUs.

The dataset refers to eight experimental sessions of the length of 2 hours each that have taken place over four days -- allocating two experimental sessions per-day. During the same day, both transceivers onboard any of the RSUs and OBUs was operated on two different frequencies. In particular, we operated the transceivers both over the licensed DSRC band, and over the unlicensed Industrial, Scientific, and Medical radio (ISM) bands 2.4GHz-2.5GHz and 5.725GHz-5.875GHz.

During each experimental session, for each transceiver, all the transmitted and received CAMs were recorded. Furthremore, for each of the received CAMs, we also recorded its Received Signal Strength Indicator (RSSI) and the location of the receiving transceiver, to generate a complete dataset of network interactions
