OverSim - Messages

Messages could be used to communicate in application & overlay layers as well for RPC communication. A message file could contain one or more messages and end with .msg. Relevant header & source files will be automatically generated when you compile. 

All messages are inherited from cMessage class &
  • RPC calls - inherited from BaseCallMessage class. Message name must end with word 'Call', e.g., MyRPCCall
    • packet MyRPCCall extends BaseCallMessage
  • RPC responce - inherited from BaseResponseMessage classes. Message name must end with word "Response', e.g., MyRPCResponce

1. Building P2P Simulators with OverSim - Where to Begin

This could be a series of blog posts about extending or developing your own OverSim applications & overlay networks. OverSim has a minimal tutorial on writing your own application & overlay network; however, it doesn't show the big picture. So, I'm wasting lots of time playing with code & trying to understand the rest. Good thing is, I like it more & more as I understand. You need to change/develop only a few things, but finding out which ones is a hell of a task. I hope this will not only make my life easy but also will be useful to new comers. Here's what you need to do: You need some background on OMNeT++ OverSim extend OMNeT++. But sometime it has its own way of doing things (to make your task even simple) so understand the differences.Develop several OMNeT++ simulators. TicToc is a good one to start with. Extend it as you imagine.Read Towards a Common API for Structured Peer-to-Peer Overlays, which is the basis for OvseSim's API. Here'…

Python Code to Calculate Gini index/coefficient, Robin Hood index, & Lorenz curve

Following Python code can be used to calculate Gini index, Gini coefficient, Robin Hood index, and points of Lorenz curve. Lorenz curve can be also plot if matplotlib is installed.
It's based on the steps given by Peter Rosenmai.

Describing Experimental/Simulation Setup

Sometimes the results of a performance analysis may depend on the computers used and/or specific features of software/libraries. In such cases it is extremely important to describe the experimental/simulation set up in details. It enables others to repeat those experiments as well as check whether the results are rigorous, statistically sound, and unbiased. Unfortunately, "Simulation Setup" is the shortest section in many research papers where authors try to save space by cutting down as much as details. Here are some tips on what to include (in addition to describing the experimental/simulation setup) based on my experiences:
Type of Simulation Are the results based on Experimentation, Emulation, or Simulation? If simulations also mention further details like whether it is Discrete Event, Montacarlo, Stochastic, or Deterministic simulation. Are the results for Steady, Dynamic, Starting/ramp-up, or Terminating state(s)?Number of Experiments/Simulations No of sampl…
