Introduction:

This is a repository for the development of WLAN IEEE 802.11ad model in ns-3. The implemented model supports the following features:

  1. DMG Channel Access Periods (BTI/A-BFT/ATI/DTI with both CBAP and Service Periods).
  2. Beamforming Training (BT) in BHI and DTI.
  3. Abstract DMG PHY layer for DMG CTRL/SC/OFDM.
  4. Fast Session Transfer (FST) Mechanism.
  5. DMG Relay Support (Full Duplex).
  6. DMG PLCP Model for 802.11ad frame.
  7. 60 GHz Directional Antenna Model.

The implementation is based on the available model of WLAN IEEE 802.11 in ns-3. The following paper includes a background on IEEE 802.11ad, implementation details, and evaluation section for this model. If you use our model in your research, please cite the following paper:

Implementation and Evaluation of a WLAN IEEE 802.11ad Model in ns-3. Hany Assasa, Joerg Widmer (June 2016) The Workshop on ns-3 (WNS3 2016), 15-16 June 2016, Seattle, WA, USA

Project Road-map:

We are planning to develop and add the following features to the project:

  1. Half Duplex DMG Relay Support.
  2. Fast Link Adaptation.
  3. Dynamic Channel Allocation (Polling).
  4. Reverse Direction Protocol (RDP).
  5. Statistical Channel Model + Raytracing Model for Millimeter-Wave Band.
  6. Beamformed Link Maintenance.
  7. Decentralized Clustering.
  8. Spatial Sharing.

If you are willing to work on one of the previous features, we are happy to collaborate.

Prerequisites:

Before start using the 802.11ad model, please keep the following in mind:

  1. Understand WLAN IEEE 802.11 MAC/PHY operations. There are plenty of references on the Internet describing CSMA/CA protocol and the evolution of 802.11 protocol.
  2. Get familiar with ns-3 and how to run simulations in ns-3. Have a look on the tutorial page of the simulator.
  3. Understand the existing Wifi Model in ns-3 which implements WLAN IEEE 802.11a/b/g/n/ac.
  4. Finally, do not contact me asking how to use the model or provide you with some documentations on how to use ns-3. Simply, I will ignore your email :)

Once you have done all these steps, you can proceed with my model.

Building The Project:

The current implementation is based on ns3-25. In order to save time and evaluate the IEEE 802.11ad model only, type the following command:

./waf configure --disable-examples --disable-tests --disable-python --enable-modules='applications','core','internet','point-to-point','wifi'
./waf build

The previous command builds the required models only to run IEEE 802.11ad with its provided scripts in debug mode. To build the project in optimized mode for fast execution type the following command:

./waf configure --disable-examples --disable-tests --disable-python --enable-modules='applications','core','internet','point-to-point','wifi' --enable-static -d optimized
./waf build

Running Scripts:

The project includes different scripts located in scratch folder to test the previous listed features and mechanisms. At the beginning of each script, we include some description regarding the tested feature + network topology + expected output + usage method.

Reporting:

In case you come across a bug during the usage of the original model, please report the problem to the following email address (hany.assasa@gmail.com). In the email, please include the following:

  1. Simulation file with small description on the simulated scenario and the expected output.
  2. Exact run parameters which caused the simulation to crash.

Please do not report any problem related to your own modification of the original code.

About the Model:

The model is developed and maintained by [Hany Assasa](http://people.networks.imdea.org/~hany_assasa/ http://people.networks.imdea.org/~hany_assasa/). For more information about the author research, please check his personal website.
