Download Required: To use associateStations, first download the Communications Toolbox Wireless Network Simulation Library add-on.

Syntax

associateStations(nodeObj,associatedSTAs)
associateStations(___,Name=Value)

Description

associateStations(nodeObj,associatedSTAs) associates the list of stations (STAs) specified in associatedSTAs to the access point (AP) that you specify in nodeObj.

example

associateStations(___,Name=Value) specifies options using one or more name-value arguments, in addition to the previous syntax.

This example uses:

Open Live Script

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

In this example, you:

  1. Create and configure a WLAN with an access point (AP) node and a station (STA) node.

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

  3. Simulate the WLAN and retrieve the statistics of the AP node and the STA node.

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)
         TransmittedPackets: 135
    TransmittedPayloadBytes: 6093
            ReceivedPackets: 126
       ReceivedPayloadBytes: 1764
             DroppedPackets: 0

disp(staStats.PHY)
         TransmittedPackets: 126
    TransmittedPayloadBytes: 1764
            ReceivedPackets: 135
       ReceivedPayloadBytes: 6093
             DroppedPackets: 0

Input Arguments

collapse all

Access point, specified as a wlanNode object. You must set the Mode property of the access point's DeviceConfig property to "AP". If you configure the access point for multiple devices, you must set the Mode property of at least one of the wlanDeviceConfig objects to "AP".

Associated stations, specified as a wlanNode object or a vector of wlanNode objects. You must set the Mode property of each object's DeviceConfig property to "STA".

Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Example: BandAndChannel=[2.4 13] specifies that the AP uses the 2.4 GHz band and channel 13 to communicate with its stations.

Operating frequency band and channel number, specified as a row vector of length 2 or an N-by-2 matrix. Specify this argument to choose the frequency band and channel number that the AP uses to communicate with the STAs.

  • Associate AP non-multilink device (non-MLD) and STA non-MLDs — Specify this argument as a row vector with two elements. The first element specifies the band, with accepted values of 2.4 GHz, 5 GHz, and 6 GHz. The second element represents a valid channel number within the specified band. The wlanNode object automatically determines the default value by finding the common band and channel between the AP and STAs. The AP node and STA nodes must share a common band and channel.

  • Associate AP MLD and STA non-MLD — Specify this argument as a row vector with two elements. The vector has the same meaning as in the case of an AP non-MLD and STA non-MLDs. (since R2024b)

  • Associate AP MLD and STA MLDs — Specify this argument as an N-by-2 matrix, where each row specifies a band and channel number. The default value is a matrix that the wlanNode object creates by incorporating the band and channel of each configured link into a row. The band and channel values configured for all the links of STA nodes must match those of the associated AP node.

If you do not specify this argument, the function chooses a band and channel by finding a common value between the AP and the STAs.

Data Types: double

Full buffer traffic options, specified as "off", "on", "DL", or "UL". The four options mean the following:

  • "off" — Full buffer traffic is disabled.

  • "on" — Two-way full buffer traffic is enabled.

  • "DL" — Downlink full buffer traffic is enabled.

  • "UL" — Uplink full buffer traffic is enabled.

Data Types: char | string
