• Acronym: CSMA/CD
  • Short description: By employing an analog self-interference canceler, this MAC protocol senses the channel in transmission time and aborts in the case of unwanted signal interference.
  • Main features:
    • Real-time FPGA-based collision detection
    • Run-time MAC scheme update
    • Improving network energy efficiency and reliability
  • Conceptual figure:


  • Hardware platforms on which functionality is supported:
    • NI USRP 2952, 2953 and 2943
    • Analog self-interference canceller module
  • Testbeds where the functionality can be used: KU Leuven IBFD testbed
  • Supporting partner: KU Leuven ([email protected])
  • Usage policies for accessing software & licensing terms:
    The software for this functionality is owned by KU Leuven and will be made available as open source software free of charge for Experiments in the context of the ORCA project at least until the end of the ORCA project [June 2020). For use of the software outside or beyond the ORCA project, please contact the software owner ([email protected]) and the coordinator of the ORCA project (Ingrid Moerman, [email protected]).
    Publications and demonstrations resulting from the use of this software should clearly mention the usage of this functionality and the owner, and refer to the H2020 ORCA Project, even if the publication or demonstration takes place after the end of ORCA project.
