wirelessNetworkViewer

View wireless networks

Since R2026a

Description

Use the wirelessNetworkViewer object to view wireless networks.

Creation

Syntax

networkViewer = wirelessNetworkViewer

networkViewer = wirelessNetworkViewer(PropertyName=Value)

Description

networkViewer = wirelessNetworkViewer creates a default wireless network viewer object.

networkViewer = wirelessNetworkViewer(PropertyName=Value) sets properties using one or more optional name-value arguments. For example, RefreshRate=5 sets the refresh rate for the viewer to 5.

Properties

CanvasSize — Size of canvas

[] (default) | two-element row vector | three-element row vector

Size of the canvas, specified as one of these options.

• Two-element vector — The first element is the length, and the second is the breadth. The value of each element must be in the range (0, Inf). Units are in meters.

• Three-element vector — The elements correspond to length, breadth, and height, respectively. The values of the first and second elements can be in the range (0, Inf), while the value of the third element must be in the range [0, Inf). Note that the object currently ignores the third element and creates a two-dimensional canvas. Units are in meters.

Data Types: double

RefreshRate — Refresh rate for viewer

10 (default) | scalar in range [0.1, 100]

Refresh rate for the viewer, specified as a scalar in the range [0.1, 100].

When you increase this value, the viewer updates the plots more often, which can slow down the simulation. When you decrease this value, the viewer updates the plots less often, resulting in slower visualization of the updates.

Data Types: double

Object Functions

addNodes	Add wireless nodes to wireless network viewer
removeNodes	Remove nodes from wireless network viewer
showBoundary	Create and visualize node placement boundary on canvas
hideBoundary	Remove placement boundaries from canvas

Examples

Randomly Place Nodes and Visualize Placement

Generate and visualize the random placement of wireless nodes within a rectangular area. Using the nodePositionRandom function, you distribute ten nodes uniformly inside a 100-by-100 meter region. Then, a wirelessNetworkViewer object displays the resulting node positions.

Set the area dimensions and number of nodes.

areaLength = 100;           % Rectangle length (meters)
areaWidth = 100;            % Rectangle width (meters)
numNodes = 10;              % Number of random nodes

Generate random node positions in the rectangle.

[nodePositions,rectPoly] = nodePositionRandom( ...
    "rectangle",[areaLength areaWidth],NumNodes=numNodes);

View the positions using the wireless network viewer.

viewer = wirelessNetworkViewer(CanvasSize=[200 200]);
addNodes(viewer,nodePositions,Type="RandomNodePositions")

Show the rectangle boundary.

showBoundary(viewer, ...
    Position=[0 0 0], ...
    BoundaryShape="rectangle", ...
    Bounds=[areaLength areaWidth], ...
    Name="RectangleBoundary")

Remove the node position by uncommenting this line of code.

% removeNodes(viewer)

Hide the rectangle boundary by uncommenting this line of code.

% hideBoundary(viewer)
