Predictive Caching using Association

Full Implementation of A Novel Predictive-Collaborative-Replacement (PCR) Algorithm for MECs

Simulation Experiment

  • To run the simulation test python3 caching/test_files/compare1.py
  • The Result can be seen below

Results

Emulation Experiment

  • To Carry out the emulation experiment you will need a GNS3 platform
  • Setup and download of GNS3 is available here
  • To run the C-LSTM python3 LSTM_caching/predictive_caching.py --n=x --ip=address --result_server=z where x is the number of MECs deployed, address is the ip address of the MQTT broker, and z is the result server ip
  • TO run PCR python3 4proposed.py --n=x --ip=address --name_server=y --result_server=z where x is the number of MECs deployed, address is the ip address of the MQTT broker, y is the ip address of the name server, and z is the result server ip
  • The Results can be seen below

Result

Emulation Experiment SETUP and Installation

use the latest docker image ugwuanyi/ubuntu_tf3 and run git pull https://github.com/emylincon/caching

  • To run setup on ubuntu run the ubuntu_setup.sh
  • To run setup on alpine run alpine_setup.sh

Note for alpine use

refere to link on how to install dependencies

Installing FTP in Linux

sudo apt-get install vsftpd

Edit conf

  • change to anonymous_enable=YES
nano /etc/vsftpd.conf
/etc/vsftpd.conf
# Allow anonymous FTP? (Disabled by default).
anonymous_enable=YES
  • restart FTP Server
/etc/init.d/vsftpd restart
you can use the config file in this dir (vsftpd)
cp vsftpd.conf /etc/
  • create directory /srv/ftp/cache to be shared by MECs

To Run the Demo

GNS3 Architecture Results Follow Along Setup YouTube Video

  1. start name server
/etc/init.d/nginx start
gunicorn server:app
  1. start broker
/etc/init.d/mosquitto start
  1. setup result server
    • Pull and run setup
git pull https://github.com/emylincon/caching
cd caching
sudo sh ubuntu_setup.sh
sudo sh LSTM_ubuntu.sh
  • install FTP server on result server
sudo apt install vsftpd
cp vsftpd.conf /etc/
/etc/init.d/vsftpd restart
  1. start FTP server and SSH server on all MECs
/etc/init.d/vsftpd start ; /etc/init.d/ssh start
  1. copy ssh key from all mecs to the result server
ssh-keygen -t rsa ; ssh-copy-id osboxes@result_server_ip

6: start application

sh clean_up.sh ; cd python3 7demo.py --n=5 --ip=broker_ip --name_server=name_server_ip --result_server=result_server_ip

7: run control
