    This example uses:

    Open Live Script

    Initialize a wireless network simulator, then create and configure both an access point (AP) node and a station (STA) node. After associating the STA with the AP, you add both nodes to the simulation. Next, you set up a wireless traffic viewer for visualization and run the simulation to observe the state transitions and channel occupancy of the wireless nodes.

    Initialize the wireless network simulator.

    networkSimulator = wirelessNetworkSimulator.init;

    Create and configure the AP node.

    deviceCfg = wlanDeviceConfig(Mode="AP");
apNode = wlanNode(Name="AP",Position=[0 10 0],DeviceConfig=deviceCfg);

    Create the STA node with a default device configuration.

    staNode = wlanNode(Name="STA",Position=[5 0 0]);

    Associate the STA node with the AP node.

    associateStations(apNode,staNode,FullBufferTraffic="on")

    Add the nodes to the simulator.

    addNodes(networkSimulator,[apNode staNode])

    Create a wireless traffic viewer and add the nodes to it.

    wirelessTrafficVis = wirelessTrafficViewer;
addNodes(wirelessTrafficVis,[apNode staNode])

    Set the simulation time, and run the simulation.

    simulationTime = 0.2;
run(networkSimulator,simulationTime)

    Figure Wireless Traffic Viewer contains 2 axes objects and another object of type uigridlayout. Axes object 1 with title Channel Occupancy, xlabel Time (s), ylabel Frequency (MHz) contains 2 objects of type patch, constantline. Axes object 2 with title State Transitions Of Nodes, xlabel Time (s) contains 5 objects of type patch, constantline.

    Try exploring these additional features of the wireless traffic viewer:

    1. Disable and enable nodes from plots.

    2. Disable and enable operating states and node types.

    3. Visualize certain time and frequency durations.

    4. Export images.

    This example uses:

    Open Live Script

    Simulate a Bluetooth® Low Energy (LE) network to observe the state transitions and channel occupancy of Bluetooth nodes. Initialize the wireless network simulator, create and connect a Central and a Peripheral node, and configure On-Off traffic. After adding the nodes to the simulator and the wireless traffic viewer, run the simulation and visualize node activity.

    Initialize the wireless network simulator.

    networkSimulator = wirelessNetworkSimulator.init;

    Set simulation time.

    simulationTime = 0.2;

    Create a Central and PeripheralBluetooth LE node.

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

    Create and configure the connection between the nodes.

    cfg = bluetoothLEConnectionConfig;
configureConnection(cfg,centralNode,peripheralNode);

    Configure On-Off traffic.

    traffic = networkTrafficOnOff(DataRate=200,PacketSize=27,OnTime=Inf,OffTime=0);

    Add traffic sources.

    addTrafficSource(centralNode,traffic,DestinationNode=peripheralNode)

    Add the nodes to the simulator.

    nodes = [centralNode peripheralNode];
addNodes(networkSimulator,nodes)

    Create a wireless traffic viewer and add the nodes to it.

    wirelessTrafficVis = wirelessTrafficViewer;
addNodes(wirelessTrafficVis,nodes)

    Run the simulation.

    run(networkSimulator,simulationTime)

Axes object 1 with title Channel Occupancy, xlabel Time (s), ylabel Frequency (MHz) contains 2 objects of type patch, constantline. Axes object 2 with title State Transitions Of Nodes, xlabel Time (s) contains 4 objects of type patch, constantline.
