Application Layer Coding for Delay and Feedback Constraints Scenarios

This repository is not being actively maintained but most of the functionality of [1] has been implemented. The entire code was ported in MATLAB for further experiments which would be released shortly.

The current state of the repository emulates the work of the paper [1].

The entire code is written in python with matplotlib as the only dependency.

There are two runnable scripts:

• system.py
• simulation.py

system.py performs one transmission of n messages from a sender to receiver over a defined a channel and other parameters. simulation.py has a set of simulation as designed in the paper for easy comparison of results.

Using system.py

• All the different settings that can be used can be listed using the following command

python system.py -h

This will open the help menu enumerating all the options and how to use

• The file can be run with a particular setting as

python system.py -l 8 -n 50 -c Bernouli --scheme ICC

This will set the message length as 8 and the number of messages to be 10 transmitted over a Bernouli channel with ICC coding scheme (the scheme in the paper).

• Running with default options

python system.py

This will transmit 8 bit long 10,000 messages over a bernouli channel with erasure probability of 0.5 and feedback erasrue probability of 0.4 and packet size 4.

Using simulation.py

• It is very straightforward to run. There are five simulations currently more can be added later.

python simulation.py

This will run all the simulations with similar settings as in the paper. It will show the results as a plot on the screen. Additionally it will also store the plots in a folder name 'plots' and the results of each run in a file in 'logs' folder. The entire thing may take a few minutes to run.

• If you want to run a particular simulation use

python simulation.py -n 1

This will run the first simulation as mentioned in the paper.
