Event Simulator for Communication Networks

Create an Event Simulator for Communication Networks in C programming language. First create an event simulator and then apply it to a communication system.

Structure

The repository is divided in two exercises:

• Event Simulator Engine (MMinfinite folder)

  • Implement it in C programming Llanguage
  • Use linked list for inserting all events
  • Sort events in the list by execution time.
  • Process each event depending of their type.
  • Analyze the correct operation of the event engine, for which An M/M/∞ system is used, in which the packages come according to a Poisson process, and nothing else is transmitted, assuming a time of service negative exponential.
  • Portray in Octave the time between event arrivals and also the average time a packet stays in the system.

• Analysis of a finite sources and pure loss Communication system (FiniteSources folder)

  • Use of the simulator for the analysis of communication system
  • Use the simulator to estudy the behavior of a pico-cell of a mobile communication system.
  • Portray in Octave probability of loss according to the number of sources in the system
  • Portray time percentage that corresponds to all resources being occupied at the same time.

Code

Both folders containg same files names.

• "main.c": Main C code.
• "library2.h": Library containing all functions and constants "main.c" utilize
• "graphics.m": Octave Script where the calculus and representation (plots) are made.
