nodeMobilityConstantVelocity

Implement constant velocity mobility model

Since R2026a

Description

Use the nodeMobilityConstantVelocity object to implement constant velocity mobility model.

Creation

Syntax

constVelocityModel = nodeMobilityConstantVelocity

constVelocityModel = nodeMobilityConstantVelocity(PropertyName=Value)

Description

constVelocityModel = nodeMobilityConstantVelocity creates a default constant velocity mobility model.

constVelocityModel = nodeMobilityConstantVelocity(PropertyName=Value) sets properties using one or more optional name-value arguments. For example, RefreshInterval=3 sets the refresh interval to 3.

Note that, in the constant velocity model, a wireless node travels with a constant velocity.

Properties

Velocity — Node velocity

three-element numeric vector

Node velocity in 3-D Cartesian coordinates, specified as a three-element numeric vector. The units are in meters per second.

Data Types: single | double

RefreshInterval — Refresh Interval

0.1 (default) | nonnegative scalar

Refresh interval, specified as a nonnegative numeric scalar. The nodeMobilityConstantVelocity object updates the position and velocity information once during this refresh interval, but only when a subclass of wnet.Node request it. The units are in seconds.

Note that, if you set RefreshInterval to 0, the object updates position and velocity information immediately whenever a subclass of wnet.Node requests it.

Data Types: single | double

Examples

Create Default Constant Velocity Mobility Model

This command creates the constant velocity mobility model with all default settings.

randomWalkModel = nodeMobilityConstantVelocity

randomWalkModel = 
  nodeMobilityConstantVelocity with properties:

           Velocity: [0 0 0]
    RefreshInterval: 0.1000

Create Customized Constant Velocity Model

This syntax sets specific properties for the constant velocity mobility model using name-value arguments.

randomWalkModel = nodeMobilityConstantVelocity( ...
    Velocity=[2 1 0], ...          % velocity vector in m/s along x, y, z axes
    RefreshInterval= 0.1)          % Refresh every 0.1 seconds

randomWalkModel = 
  nodeMobilityConstantVelocity with properties:

           Velocity: [2 1 0]
    RefreshInterval: 0.1000
