An Accurate, Scalable, Communication Effects Servers for the FCS System of Sytems Simulation Environment

QualNet Network Simulator used to evaluate the performance of the CES

The ultimate objective of the FCS CES is to support real-time simulation of wireless networks with very large numbers of communicating devices at a sufficiently high level of accuracy that the simulation can interoperate with both physical test articles and human participants

See the whitepaper to learn the key design attributes of why QualNet was chosen:

  • Modular interfaces among protocol stack layers to support detailed, accurate models throughout the protocol stack, including the physical layer
  • Transparent parallel execution of network simulation models on diverse parallel architecture, including shared-memory multiprocessors, distributed memory multi-computers, and cluster computers
  • Well-defined external interfaces to support inter-operability (via DIS, HLA, or socket connections) with other software

    Key Features of QualNet


    Faster speed enables model developers and network designers to run multiple "what-if" analyses.


    Our QualNet network simulation tool can model large networks with high fidelity.

    Model Fidelity

    Our network simulation tool uses highly detailed implementation of protocol models.


    QualNet and its library of models run on a vast array of platforms.


    Connect to other hardware and software applications to greatly enhance the value of the network model.
