wnet.Node Class

Namespace: wnet

Implement custom wireless node

Since R2026a

Description

Use the wnet.Node base class to implement a custom wireless node in a subclass.

The wnet.Node class is a handle class.

Class Attributes

Abstract

true

For information on class attributes, see Class Attributes.

Properties

Position — Current node position

[0 0 0] (default) | three-element numeric row vector

Current node position in 3-D Cartesian coordinates, specified as a three-element numeric row vector. The units are in meters.

Attributes:

GetAccess	public
SetAccess	public

Data Types: double

ID — Node identifier

positive integer

Node identifier, represented as a positive integer. The class assigns ID values incrementally, starting from 1.

Attributes:

GetAccess	public
SetAccess	private

Data Types: double

Name — Name of wireless node

string scalar | character vector

Name of the wireless node, represented as a string scalar or character vector. You can set the value of this property only within the subclasses of wnet.Node. The default value of this property is of the form NodeID, where ID refers to the value of the ID property. For example, if the value of ID is 3, the default value of Name is Node3.

Attributes:

GetAccess	public
SetAccess	protected

Data Types: string | char

Mobility — Node mobility model

object of subclass of wnet.Mobility

Node mobility model, represented as an object of a subclass of wnet.Mobility class. You can set the value of this property only within the subclasses of wnet.Node.

Attributes:

GetAccess	public
SetAccess	protected

Velocity — Node velocity

[0 0 0] (default) | three-element numeric row vector

Node velocity in 3-D Cartesian coordinates, represented as a three-element numeric row vector. The units are in meters per second. You can set the value of this property only within the subclasses of wnet.Node.

Attributes:

GetAccess	public
SetAccess	protected

Data Types: double

How to Use wnet.Node Base Class

To create a custom node using the wnet.Node base class, follow these steps.

1. Implement the custom node subclass:

   • Inherit from the wnet.Node base class. The class definition must have this format, where customNode is the name of your custom node subclass.

     classdef customNode < wnet.Node
         ...
     end

   • Override any of the base class public methods.

   Save the class definition in a .m file.

2. In a simulation script, create an object of the customNode.
