Emulate mobile network latency based on large-scale real-world measurements.
This repository provides several netem latency profiles for emulating mobile networks. One can choose among several operators, radio access technologies and signal quality. All measurements are taken from real-world measurements, thanks to the MONROE mobile nodes.
We provide data for X operators over X countries. Moreover we provide separate scenarios for radio access technology (3G, 4G), signal strength, and whether the SIM card was in roaming.
We offer netem distribution files. They can be used with the netem tool, by copying them to the /usr/lib/tc directory. Note that netem distributions are normalized over average and standard deviation, and, as such, you must specify such values when using them. Our convenience scripts do this for you.
The code has been tested under Ubuntu 18.04. You only need the tc/netem tool which is generally installed by default.
You can use our convenience scripts that you find in this repository.
To start imposing latency on an interface, just run:
./start_shaping [interface] [profile_name]
To stop shaping run:
./stop_shaping [interface]
