Sprinkler

An efficient IPv6 Multicast Protocol for distributing data over a wireless network.

It uses:

1. Luby-Transform Codes
2. Trickle Algorithm

Usability over

• 802.11 WLAN ad-hoc networks with Raspberry Pis and GNU/Linux computers

Usage

Case:

python3 Sprinkler.py
--version 1 --path /path/to/dir/
--filename file_to_send --group ff32::2
--port 30002

will distribute the file /path/to/dir/file_to_send over the wireless ad-hoc network Nodes which are running the same code but will lower version number (for instance 0). The /path/to/dir will also store all new incoming files.

General:

usage: Sprinkler.py [-h] [-V VERSION] [-b BLOCK] [-pt PATH] [-f FILENAME]
                [-g GROUP] [-p PORT]

Sprinkler Wireless Data Dissemination Protocol

optional arguments:
-h, --help            show this help message and exit
-V VERSION, --version VERSION
                    Version Number for Updated Data
-b BLOCK, --block BLOCK
                    Encoding Block Length, keep it less than 1500B
-pt PATH, --path PATH
                    Path to the file for Dissemination / storing Incoming
                    file over channel. Default is
                    current_folder/transmissions
-f FILENAME, --filename FILENAME
                    Main File for Fountain. provide complete path
-g GROUP, --group GROUP
                    IPv6 Multicast Group. Default is ff02::1
-p PORT, --port PORT  port number. Default is 30001

Setup

sudo ./setup.sh

This file will:

• Check for python3 and pip3

• install the lt-code pip module

• make necessary folders for the API and relevant dummy files for default operation

• creates routeTable.json for storing information of nearby neighbors and source of information fountain

Application

• Currently being used in TWIN Testbed at the Sustainable Communication Networks, University of Bremen, Germany to distribute firmware over 802.11 WLAN back-channel

Dependencies

It uses LT-Code Github Repository by Anson Rosenthal

install pip3 module first using:

sudo pip3 install lt-code
