Simulate a wireless local area network (WLAN) using WLAN Toolbox™ with the Communications Toolbox™ Wireless Network Simulation Library.

In this example, you:

Check if the Communications Toolbox™ Wireless Network Simulation Library support package is installed. If the support package is not installed, MATLAB® returns an error with a link to download and install the support package.

wirelessnetworkSupportPackageCheck;

Create a wireless network simulator.

networksimulator = wirelessNetworkSimulator.init();

Create a wlanDeviceConfig object, specifying the operating mode and beacon interval. Use this configuration to create a WLAN node and specify its name and position.

deviceCfg = wlanDeviceConfig(Mode="AP",BeaconInterval=5);
apNode = wlanNode(Name="AP",Position=[0 10 0],DeviceConfig=deviceCfg);

Create a WLAN node with the default device configuration. Confirm that the default mode is STA.

staNode = wlanNode(Name="STA",Position=[5 0 0]);
disp(staNode.DeviceConfig.Mode)

STA

Add a random waypoint mobility model to the WLAN node with the default device configuration. Set the shape of the node's mobility area to "circle".

addMobility(staNode,BoundaryShape="circle");

Associate the STA node with the AP node using the associateStations function.

associateStations(apNode,staNode);

Create a networkTrafficOnOff object to generate an On-Off application traffic pattern. Specify the data rate in kilobits per second and the packet size in bytes.

traffic = networkTrafficOnOff(DataRate=100,PacketSize=10);

Add application traffic from the AP node to the STA node.

addTrafficSource(apNode,traffic,DestinationNode=staNode);

Add the AP node and STA node to the wireless network simulator.

addNodes(networksimulator,{apNode,staNode});

Set the simulation time in seconds and run the simulation.

simulationTime = 0.05;
run(networksimulator,simulationTime);

Get and display the physical layer (PHY) statistics that correspond to the AP node and STA node.

apStats = statistics(apNode);
staStats = statistics(staNode);
disp(apStats.PHY)
