    Syntax

    addNodes(networkSimulator,nodes)

    Description

    addNodes(networkSimulator,nodes) adds the specified wireless nodes to the wirelessNetworkSimulator object. You must add the nodes to the simulator before running the simulation.

    This example uses:

    Open Live Script

    Create a wirelessNetworkSimulator object by using the wirelessNetworkSimulator.init() function. By default, the wirelessNetworkSimulator object applies free-space path loss model for the channel effects.

    networkSimulator = wirelessNetworkSimulator.init();

    Create two Bluetooth BR nodes, one with the "central" role and other with the "peripheral" role. Specify the position of the Peripheral node in meters.

    centralNode = bluetoothNode("central");
peripheralNode = bluetoothNode("peripheral",Position=[1 0 0]);

    Create a default Bluetooth BR connection configuration object to configure and share a connection between Bluetooth BR Central and Peripheral nodes.

    cfgConnection = bluetoothConnectionConfig;

    Configure connection between the Central and the Peripheral nodes.

    connection = configureConnection( ...
    cfgConnection,centralNode,peripheralNode);

    Create and configure a networkTrafficOnOff object to generate an On-Off application traffic pattern.

    traffic = networkTrafficOnOff( ...
    DataRate=200, ...
    PacketSize=27, ...
    OnTime=inf);

    Add application traffic from the Central to the Peripheral node.

    addTrafficSource(centralNode,traffic, ...
    DestinationNode=peripheralNode);

    Add the Central and Peripheral nodes to the wireless network simulator.

    addNodes(networkSimulator,[centralNode peripheralNode]);

    Specify the simulation time in seconds.

    simulationTime = 0.05;

    Run the simulation for the specified simulation time.

    run(networkSimulator,simulationTime);

    Retrieve application, baseband, and physical layer (PHY) statistics corresponding to the Central and Peripheral nodes.

    centralStats = statistics(centralNode)
    centralStats = struct with fields:
        Name: "Node1"
          ID: 1
         App: [1×1 struct]
    Baseband: [1×1 struct]
         PHY: [1×1 struct]


    peripheralStats = statistics(peripheralNode)
    peripheralStats = struct with fields:
        Name: "Node2"
          ID: 2
         App: [1×1 struct]
    Baseband: [1×1 struct]
         PHY: [1×1 struct]

    Input Arguments
