StationaryMobility¶

simple module StationaryMobility

Mobility module for stationary nodes.

Usage diagram¶

Inheritance diagram¶

Used in compound modules¶

Name	Type	Description
AccessPoint	compound module	A wireless access point device that connects wireless stations (like WirelessHost) to a wired network. Supports multiple wireless radios and multiple Ethernet ports.
Probe	compound module	A minimal wireless network node that consists only of an antenna and mobility model. Designed for monitoring wireless signals without actively participating in network communication.
NoiseSource	compound module	A network node that generates periodic noise transmissions that can interfere with wireless communications. Alternates between sleep and transmission states based on configurable intervals. Uses a NoiseTransmitter to create noise signals with specified duration, frequency, bandwidth, and power parameters. Useful for testing protocol robustness against interference in wireless networks.

Known subclasses¶

Name	Type	Description
StaticLinearMobility	simple module	Mobility model which places all hosts at constant distances in a line with an orientation

Extends¶

Name	Type	Description
MobilityBase	simple module	Abstract base module for mobility models.

Parameters¶

Name	Type	Default value	Description
displayStringTextFormat	string	“p: {position}\nv: {velocity}”	Determines the text that is written on top of the submodule, supports displaying pars, watches, and module-specific information
subjectModule	string	“^”	The module path that determines the subject module, the motion of which this mobility model describes. The default value is the parent module
coordinateSystemModule	string	“”	The module path of the geographic coordinate system module; optional, empty disables geographic conversion (and the {geo_position} directive)
updateDisplayString	bool	true	Enables continuous update of the subject module’s position by modifying its display string
constraintAreaMinX	double	-inf m	The minimum x position of the constraint area. It is unconstrained by default (negative infinity)
constraintAreaMinY	double	-inf m	The minimum y position of the constraint area. It is unconstrained by default (negative infinity)
constraintAreaMinZ	double	-inf m	The minimum z position of the constraint area. It is unconstrained by default (negative infinity)
constraintAreaMaxX	double	inf m	The maximum x position of the constraint area. It is unconstrained by default (positive infinity)
constraintAreaMaxY	double	inf m	The maximum y position of the constraint area. It is unconstrained by default (positive infinity)
constraintAreaMaxZ	double	inf m	The maximum z position of the constraint area. It is unconstrained by default (positive infinity)
initialX	double	uniform(this.constraintAreaMinX, this.constraintAreaMaxX)
initialY	double	uniform(this.constraintAreaMinY, this.constraintAreaMaxY)
initialZ	double	nanToZero(uniform(this.constraintAreaMinZ, this.constraintAreaMaxZ))
initialLatitude	double	nan deg
initialLongitude	double	nan deg
initialAltitude	double	0m
initialHeading	double	0deg
initialElevation	double	0deg
initialBank	double	0deg
initFromDisplayString	bool	true	Enables one-time initialization from the subject module’s display string
updateFromDisplayString	bool	true	Enables continuous update from the subject module’s display string for dragging and rotating it

Properties¶

Name	Value	Description
class	StationaryMobility
display	i=block/cogwheel

Signals¶

Name	Type	Unit	Description
mobilityStateChanged	inet::MobilityBase		It works in inet, but not in the extended module in another namespace
