ipfs-experiment

IPFS experiment code file

It shows communication between 2 raspberri pi clients, 1 command_client, and 1 main server.

• Script Setting
  • basic script file is command.txt
  • A B C (A is node's order. B is option number where 0 is parallel and 1 is sequential. C is command line.
  • 'head -c 1024 < /dev/urandom > test_file1' is generating 1024 Bytes file as test_file1.
  • 'ipfs add test_file1' is uploading the test_file1 in IPFS environment.
  • 'ipfs cat $1 > read_file1' is downloading the file from other nodes connecting in IPFS environment.

Testing

• Environment setting

  • We need total 4 terminals to implement testing
  • We need to install some packages in raspberry pi environment
    • pip3 install pandas
    • sudo apt-get install libatlas-base-dev
    • pip3 install os
    • pip3 install psutil

• Implement

  • python3 Main_server.py
  • python3 rc_0.py info.csv
  • python3 rc_1.py info.csv
  • python3 Comm_client.py info.csv command.txt

• Result

  • If you do 'Ctrl-C' Comm_client.py, terminal is terminated and generates the csv file including the command, timestamp, and results.

• Reset

  • reset.py is the file that removes the files in .ipfs/blocks in order to reduce the embedded device's capacity and adds the SHARDING file because IPFS needs the file in .ipfs/blocks.
