=== 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 three main pieces to this effort:  a realtime simulator scheduler, a net device that allows ns-3 stacks to send data on real networks(EmuNetDevice), and a bridge that allows real hosts to send data on ns-3 networks (TapBridge).
* ''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.
Future work involves better integration with the ORBIT wireless testbed and the CORE research emulator.

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.

Developer home pages

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. Note also that a lot of code is under review for the main tree and is listed here:

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

Synchronous posix/sockets API

802.21 media independent handover

IPv6 for ns-3

WiMAX module

Underwater acoustic model

Verification, Validation and Testing

Verification is the process of making sure that a given computer program you have built implements your conceptual model correctly. Validation means the ability to determine that a given model has some connection to some reality -- that a model is an accurate representation of a real system. Testing means the ability to exercise a given model to determine that it behaves as expected given various good (and perhaps bad) inputs (and does not change unexpectedly over time). Note the perhaps subtle differences.

  • summary: Add support for model verification, validation and testing.
  • wiki pages: See VerificationValidationAndTesting
  • status: Thinking about these features is just beginning. If you have any suggestions, feel free to chime in on the list.

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)

George Riley has made a prototype animator for PointToPoint links.

Joe Kopena is working on what he calls a "decorator" http://code.nsnam.org/tjkopena/

Hagen Paul Pfeifer is working on a MANET visualizer http://nv.dev.jauu.net/

real-world application integration

Parallel simulations

Delay Box for ns-3

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

Suggested Projects

2009 Google Summer of Code Project Ideas

We have posted some project ideas for Google Summer of Code. However, these ideas are not limited to the Google program.

Project ideas here

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.
