Group member

Jianfeng Xia(jxia11), Cheng Hu(chenghu3)

Environment

Go 1.11.4, Python 36

Design & Evaluation

For details of algorithms & system design and performance evalution, please refer:

• docs/CS425_MP2_CP1_Report.pdf
• docs/CS425_MP2_CP2_Report.pdf

Usage

• The service should be run at VM number 7, port 8888

• Log into group VMs and clone repository

• To build: go build client.go

• Run program: ./client PORT
  Alternatively, use our Python3 script experiment.py to start multiple clients (starting a node every 0.5s) and write stdout to logfiles.
  Usage of Python script:
  python36 experiment.py [NUMBER OF CLIENTS]

• Plotting: We have also included scripts to analyze performance and generate plots. To run the scripts:

  • cd logs
  • python3 propagation.py
  • python3 bandwidth.py

  Note:

  1. Our plot scripts use matplotlib and numpy, we suggest to run those scripts on machine has those library.
  2. Because the log files are large(we use logs in the case of 100 nodes, 20 mesg/s), please be patient when running scripts.
