ns-3 presently doesn't include any support for simulation of optical networks in the official distiribution, however there are modules under development. This page tracks info about modules for ns-3 developed in field of optics, including WDM and PON.

Optical Transport Network: Prototype WDM Network Simulator (PWNS)

PWNS project logo

Project name

Project name is a parody on OWns[1], a project with similar goals implemented in ns-2.

Project scope

The goal of PWNS project is to implement models for WDM optical network components, including:

  • optical cable, optical fiber, wavelength channel,
  • multiplexer and demultiplexer, add-drop multiplexor,
  • wavelength converter, wavelength selective switch, arrayed waveguide grating,
  • optical cross connect (MEMS).

Prototype from June 2012 is described in [2]; more detailed description will be posted here as soon as possible.

Radio over Fiber

Project scope

The goal of our work is to investigate and optimize the performance of MAC (Medium Access Control) radio protocols when it is used in a RoF (Radio-over-Fiber) architecture. Our study is mainly focused on IEEE 802.11 over RoF transmissions. We developed a RoF model in ns-3 based on the YANS Wi-Fi model which enables the simulation of 802.11 RoF systems. The current model includes [1]:

  • Distributed Antenna Systems RoF modeling;
  • Optical module computing delays and attenuations undergone by the radio signal transmission over fiber links.

Further points to be implemented:

  • Protocol-independent model (not limited to Wi-Fi transmissions);
  • Integration of optical network component models developed by PWNS (Prototype WDM Network Simulator).
