p2p Name-Defined Network

This repository is a group project for the TCD module CS7NS1: Scalable Computing. Our aim is to create a peer-to-peer (p2p) name-defined network designed for communication across multiple Raspberry Pi devices. The project is exemplified with an underwater mission emulation.

Group 4 NDN Run Instructions

To run our two name-defined networks on independent Raspberry Pi's, follow these instructions:

On any one of the Pi(s):

1. Cd into the project folder.
2. Run the command: source .tmux/centralNode

On Pi 1:

1. Cd into the project folder.
2. Run the command: source .tmux/ndn-crops
   • This starts the crop network.

On Pi 2:

1. Cd into the project folder.
2. Run the command: source .tmux/ndn-soils
   • This starts the soil network.

On either or both Pi(s):

1. Run the command: tmux attach
   • This allows you to interface with the nodes in the network.
2. To see a list of selectable nodes, press Ctrl+b and then w.
3. Select a node with the arrow keys and press enter to use the node's terminal.
4. The node's command line prompts to 'Ask the network for information:'.
   • Type in some data name from the list of data names at the end of this document. If an invalid name is typed, the data won’t send.
5. Wait for the data to return. You can track the routing by switching to other nodes.
6. To exit tmux, press Ctrl+b and then d.
7. To kill the network and all running ports, enter the command: tmux kill-server

Network Structure

The network is divided into two types of devices - nodes and sensors.

• Sensors are devices with three-level names, such as /soils/soil4/temperature.
• Nodes are devices with two-level names, such as /soils/soil4.

Nodes with two-level names can access data from every other sensor or node. If an attempt is made to get data from sensors away from its node network, it will fail to retrieve the data. However, nodes can retrieve data from all sensors in the entire network of networks.
