Benchmark Script

This experiment is for end-to-end connection and focuses on iperf, DDS, and Zenoh transmission performance.

Prerequisite

• Network environment: Wi-Fi6, 4G
• CycloneDDS (installation guide)
• Zenoh (installation guide)

⚠️ Warning: It is necessary to ensure that the car endpoint can establish an SSH connection with the RSU endpoint.

⚠️ Warning: All operations are executed only on the car's side.

Check the configuration

• Edit the config.properties file and verify that all parameters in the file are correctly configured.

Iperf experiment

• install iperf3

sudo apt install iperf3

• measure latency

./lat_car.sh <network> <distance> <timeout>
(e.g., ./lat_car.sh wifi6 10 10)

# <network>: wifi6 or 4glte
# <distance>: distance in meters.
# <timeout>: timeout in seconds.

# Tips: Commands in the following sections follow this convention.

# The output data will be under the ' ./car_log/<experiment_name>/latency/ ' directory.

• measure throughput

./thr_car.sh <network> <distance> <timeout>

# The output data will be under the ' ./car_log/<experiment_name>/throughput/ ' directory.

DDS experiment

• measure latency

./dds_lat_car.sh <network> <distance> <timeout>

# The output data will be under the ' ./car_log/<experiment_name>/dds_latency/ ' directory.

• measure throughput

./dds_thr_car.sh <network> <distance> <timeout>

# The output data will be under the ' ./car_log/<experiment_name>/dds_throughput/<network>/<distance> ' directory.

# The filename represents the payload.

Zenoh experiment

• measure latency

./zenoh_lat_car.sh <network> <distance>

# The output data will be under the ' ./car_log/<experiment_name>/zenoh_latency/<network>/<distance> ' directory.

# The filename represents the payload.

• measure throughput

./zenoh_thr_car.sh <network> <distance>

# The output data will be under the ' ./car_log/<experiment_name>/zenoh_throughput/<network>/<distance> ' directory.

# The filename represents the payload.

# The larger payload experiments will take time.
