iOT-benchmarking

IoT Benchmarking of La trobe Campus WiFi Speeds using Raspberry Pi 4

Running docker container on Raspberry Pi

• docker run --privileged -d --name cronspeed --restart unless-stopped sudipta20449667/pythondocker:latest
• crontab -e
  • Add * * * * * /home/pi/cron.sh >> /home/pi/speedtests.log add the very bottom to check for updates every minute

Building the code

Manual

• pip install -r requirements.txt
• export LATCS7_USERNAME=MY_LATCS7_USERNAME
• export LATCS7_PASSWORD=MY_PASS_WORD
• export DEVICE_ID=1
• python3 start.py --sleep_minutes 15
  • --sleep_minutes is optional

deployment

• Create a branch for your code
• git checkout -b arm32v7 myFeatureBranch
• push your work to your branch
• merge with arm32v7
• the updated container will run automatically on Raspberry pi after github workflow finished successfully by roughly a minute

ManualTest class

Custom server testing was separated to a file to separate changes in code functionality.

Method	return	parameters
Constructor	ManualTest	-
ping_once: pings the custom server once	time in milliseconds: double	packet_size:int (optional) default is 56
ping: calls the function ping_once N times (default is 10)	average_time_in_milliseconds: double	N:int (optional) default is 10
download_once: measures download speed once	speed: double	filesize:int unit is Mb. For example 1 for 1Mb
download: calls the function download_once N times (default is 10)	average_speed: double	N:int (optional) default is 10
upload_once: measures upload speed once	speed: double	filesize:int unit is Mb. For example 1 for 1Mb
upload: calls the function upload N times (default is 10)	average_speed: double	N:int (optional) default is 10

Out of the box usage example

  st = Speedtesting()
    while 1:
     st.test_all()
     time.sleep(15) # every 15 seconds
