On this page, we will try to maintain pointers to current ns-3 development work, and post some suggested project ideas.

If you are interested in collaborating on one of these projects, please do not hesitate to contact the individuals identified.

For newcomers: Contributing to ns-3

Note: Several ns-3 developers hang out on IRC at #ns-3 at irc.freenode.net. A typically active time is around 1500 to 1900 UTC, Mondays through Fridays.

Here are some developer pages, to see what people are currently working on:

Current Development Projects

Below is a list of projects that are being worked on and have been publicly announced. Please add your project to the below so interested contributors can coordinate with you.

802.11 model extensions

There are several efforts ongoing to extend the ns-3 Wifi model.

Harmonization with ns-2 802.11 Ext models

  • summary: ns-2.33 added a new 802.11 model with much more detailed channel modeling. An effort has been started to port over reusable components from that implementation to ns-3's wifi model, while reusing already implemented basic components. The goal is a harmonization of the 802.11 models of ns-2 and ns-3. Leading aim is to support research on vehicular networks. Planned near-term features:
    • Equalizing PHY models including capture effects, user-definable coding rates (e.g. 5.9 GHz from 802.11p)
    • EDCA QoS extensions of 802.11e
  • Already finished features:
    • Nakagami/Rayleigh propagation loss model
  • ns-developers post: http://mailman.isi.edu/pipermail/ns-developers/2008-November/004936.html
  • code location: http://idlebox.net/2008/ns-3-wifi/code/ns-3-wifiex/
  • status: under current active development. Time frame till this is completed: 4-5 month.

802.11n

  • summary: University of Florence (LART lab) has begun work on an 802.11n model for ns3. The main goal is to simulate the frame aggregation feature. In the future, they aim to implement the High Throughput terminal behaviour with MIMO technology. They plan to add, to ns-3's 802.11 model, the following 802.11n features:
    • Frame Aggregation
    • Block ACK
    • HCF (EDCA and support for HCCA)
    • TXOP
    • HT terminal (also with protection modes)
    • MIMO

Also interested to verify the 11n terminal throughput when are associated terminal of a/b/g standards.

802.11s

  • summary: Wireless Software Research & Development Group of Institute of Information Transmission Problems of the Russian Academy of Sciences is aiming to make a complete model of IEEE802.11s D2.0 Draft Standard.
  • ns-developers post: http://mailman.isi.edu/pipermail/ns-developers/2008-November/004931.html
  • code location: (none posted yet)
  • status: just announced

ns-3 Emulation and Realtime Scheduler

In this context, emulation means the ability to arange for the simulator to generate and consume data from the network in real time. There are two main pieces to this effort: a realtime simulator scheduler and prototypical net devices that allow connection to real system hardware.

  • summary: Add support for various forms of emulation
  • wiki page: Emulation and Realtime Scheduler
  • status: The realtime scheduler was in ns-3.2. The EmuNetDevice was in ns-3.3. The TapBridge was in ns-3.4.

The basic work on this project is complete.

Visualization for ns-3

Jeremy Norman and the iNSpect team have posted some plans for a visualization library for ns-3:

Gustavo Carneiro is working on a Python visualization tool (http://code.nsnam.org/gjc/ns-3-pyviz)

real-world application integration

Statistics for ns-3

Tag rework

Parallel simulations

Delay Box for ns-3

Matt Crinklaw is working on a port of ns-2 DelayBox to ns-3.

Suggested Projects

Ns3 Wireless PHY

This project aims at building a high-quality set of PHY-level models for wireless networks: Ns3WirelessPhy

Mathieu Lacage is coordinating this work and has a workshop session at wns3 in March 2009.

Traffic generation applications

George Riley (riley@ece.gatech.edu) is overseeing the porting of application models from GTNetS to ns-3.
