Introduction

This project implements a Handover or Handoff (HO) operation using reinforcement learning (RL) techniques. It focuses on training an agent to perform HO operations effectively in a simulated environment that is satellite communication environment. This project includes two parts designed to perform Handover: inter-satellite HO (Satellite HO) and intra-satellite HO (Spotbeam HO). The reinforcement learning algorithm employed here enables the agent to learn and adapt its actions to achieve optimal performance.

Requirements

List the software and libraries required to run your project :

• Python 3.x
• OpenAI Gym
• stable-baselines3
• pygame
• tensorboard

You can also include any hardware requirements if necessary.

Installation

1. Clone the repository to your local machine:

   git clone https://github.com/RezaEs79/Bachelor-Project.git
   

2. To install dependencies (It works on both Linux and Windows) :

    pip install  gym
    conda install stable-baselines3
    conda install multipledispatch
    conda install pygame
    pip install Shimmy
    conda install -c conda-forge tensorboard
   

3. Also, for any possible errors, these may be useful:

    pip install stable-baselines3[extra]
    pip install tensorflow --upgrade --force-reinstall
    pip install stable-baselines3[extra] --upgrade --force-reinstall
    pip3 install torch torchvision torchaudio

Usage

To use this project, follow these steps:

• Chose your handover scenario in satellite communication: Proj1 is inter satellite HO and Proj2 is intra satellite HO. You can try following command to test whether it works or not:

  # in Proj1
  python Test.py

  or :

  # in Proj2
  python mytest.py

• Train the RL Agent: Train the reinforcement learning agent to optimize handover operations.

• Test the Agent: Evaluate the agent's performance and visualize the results.

Train

To train the reinforcement learning agent, run the following command:

python Model_builder.py

and then type ppo or a2c or dqn for your specific algorithm.

Testing

To test the trained agent and evaluate its performance, use the following command:

python Model_runner.py

and then type ppo or a2c or dqn for your specific algorithm.

Results

For watching results obtained from your project, such as performance metrics, graphs, and visualizations. use codes in MATLAB_Codes folder and results that writed in .txt file.
