Click-MAC Extensions for ns-3-click

  • Student: Ashwin Narayan
  • Mentors: Ruben Merz and Lalith Suresh
  • Abstract: This project deals with the MAC extensions for ns-3 click. The current integration of the Click Modular Router with ns-3 is confined to only ns-3’s network device types and doesn’t yet permit the use of Click’s Wifi MAC specific elements. This project aims to enable the same by implementing Radiotap support, and a Monitor Wifi Mac High interface.


Overview GSoC 2010 saw the integration of the Click Modular Router with ns-3. The implementation, however, is limited only to layer 3 or in other words, Click's use is confined only to all of ns-3's network device types. This project deals with making Click's Wifi MAC specific elements compatible with ns-3-click.

Details A major step in the project would be the implementation of full radiotap headers support. The radiotap header cannot simply be added in YansWifiPhy as this would create issues with the current implementations of MacLow and MacRxMiddle. The current NS-3 Click integration is limited to L3 and leaves ns-3 to handle L2. The radiotap header would probably best be added on the receiver path as close to NetDevice as possible. The implementation would require a redesign in the method of packet forwarding with the radiotap pertinent data. The radiotap header could be created in MacLow and the necessary modifications must be made for sending the header upwards.
