wnet.Mobility Class

Namespace: wnet

Implement custom mobility model

Since R2026a

Description

Use the wnet.Mobility base class to implement a custom mobility model in a subclass.

The wnet.Mobility class is a handle class.

Class Attributes

Abstract

true

For information on class attributes, see Class Attributes.

Properties

RefreshInterval — Refresh interval

0.1 (default) | nonnegative numeric scalar

Refresh interval, specified as a nonnegative numeric scalar. The wnet.Mobility class updates the position and velocity information once during this refresh interval, but only when a subclass of wnet.Node requests it. The units are in seconds. If you set RefreshInterval to 0, the node updates position and velocity information immediately whenever you request it.

Attributes:

GetAccess	public
SetAccess	protected

Data Types: double | single

Methods

Public Methods

mobilityInfo	Obtain position and velocity of wireless node
init	Initialize mobility context
copy	Copy mobility model

How to Use wnet.Mobility Base Class

To create a custom mobility model using the wnet.Mobility base class, follow these steps:

1. Implement the custom mobility subclass:

   • Inherit from the wnet.Mobility base class. The class definition must have this format, where myCustomMobility is the name of your custom mobility class.

     classdef myCustomMobility < wnet.Mobility
         ...
     end

   • Override the base class public method wnet.Mobility.mobilityInfo. Optionally, you can also override the public method init.

   Save the class definition in an .m file.

2. In a simulation script, create an object of the myCustomMobility class. Plug this custom mobility object into a wireless node inherited from the wnet.Node base class by using the addMobility object function.
