DeepCoMP: Self-Learning Dynamic Multi-Cell Selection for Coordinated Multipoint (CoMP)

DeepCoMP: Self-Learning Dynamic Multi-Cell Selection for Coordinated Multipoint (CoMP)

Deep reinforcement learning for dynamic multi-cell selection in CoMP scenarios. Three variants: DeepCoMP (central agent), DD-CoMP (distributed agents using central policy), D3-CoMP (distributed agents with separate policies). All three approaches self-learn and adapt to various scenarios in mobile networks without expert knowledge, human intervention, or detailed assumptions about the underlying system. Compared to other approaches, they are more flexible and achieve higher Quality of Experience.

Setup

You need Python 3.8+. You can install deepcomp either directly from PyPi or manually after cloning this repository.

Simple Installation via PyPi

sudo apt update
sudo apt upgrade
sudo apt install cmake build-essential zlib1g-dev python3-dev

pip install deepcomp

Manual Installation from Source

For adjusting or further developing DeepCoMP, it's better to install manually rather than from PyPi. Clone the repository. Then install everything, following these steps:

# only on ubuntu
sudo apt update
sudo apt upgrade
sudo apt install cmake build-essential zlib1g-dev python3-dev

# clone
git clone [e-mail]:CN-UPB/DeepCoMP.git
cd DeepCoMP

# install all python dependencies
pip install .
# "python setup.py install" does not work for some reason: https://stackoverflow.com/a/66267232/2745116
# for development install (when changing code): pip install -e .

Tested on Ubuntu 20.04 and Windows 10 with Python 3.8.

For saving videos and gifs, you also need to install ffmpeg (not on Windows) and ImageMagick. On Ubuntu:

sudo apt install ffmpeg imagemagick

Usage

# get an overview of all options
deepcomp -h

For example:

deepcomp --env medium --slow-ues 3 --agent central --workers 2 --train-steps 50000 --seed 42 --video both

To run DeepCoMP, use --alg ppo --agent central. For DD-CoMP, use --alg ppo --agent multi, and for D3-CoMP, use --alg ppo --agent multi --separate-agent-nns.

By default, training logs, results, videos, and trained agents are saved in <project-root>/results, where <project-root> is the root directory of DeepCoMP. If you cloned the repo from GitHub, this is where the Readme is. If you installed via PyPi, this is in your virtualenv's site packages. You can choose a custom location with --result-dir <custom-path>.

Accessing results remotely

When running remotely, you can serve the replay video by running:

cd results
python -m http.server

Then access at <remote-ip>:8000.

Tensorboard

To view learning curves (and other metrics) when training an agent, use Tensorboard:

tensorboard --logdir results/train/ (--host 0.0.0.0)

Tensorboard is available at http://localhost:6006 (or <remote-ip>:6006 when running remotely).

Scaling Up: Running DeepCoMP on multiple cores or a multi-node cluster

To train DeepCoMP on multiple cores in parallel, configure the number of workers (corresponding to CPU cores) with --workers.

To scale training to a multi-node cluster, adjust cluster.yaml and follow the steps described here. Set --workers to the total number of CPU cores you want to use on the entire cluster.

Documentation

API documentation is on https://cn-upb.github.io/DeepCoMP/.

Documentation is generated based on docstrings using pdoc3:

# from project root
pip install pdoc3
pdoc --force --html --output-dir docs deepcomp
# move files to be picked up by GitHub pages
mv docs/deepcomp/ docs/
# then manually adjust index.html to link to GitHub repo
