Simple Module ConstSpeedMobility

Package: org.mixim.modules.mobility
File: modules/mobility/ConstSpeedMobility.ned

Controls all movement related things of a host

ConstSpeedMobility does not use one of the standard mobility approaches. The user can define a velocity for each Host and an update interval. If the velocity is greater than zero (i.e. the Host is not stationary) the ConstSpeedMobility module calculates a random target position for the Host. Depending to the update interval and the velocity it calculates the number of steps to reach the destination and the step-size. Every update interval ConstSpeedMobility calculates the new position on its way to the target position and updates the display. Once the target position is reached ConstSpeedMobility calculates a new target position.

Extends:

BaseMobility (simple module)

Module which is responsible for mobility related information like position and movement BaseMobility itself defines a static mobility pattern (means only a position, no movement). Mobility modules which extend from this module will define more complex movement patterns.

Parameters:

Name	Type	Default value	Description
notAffectedByHostState	bool	true
coreDebug	bool		debug switch for the core framework
x	double		x coordinate of the nodes' position (-1 = random)
y	double		y coordinate of the nodes' position (-1 = random)
z	double		z coordinate of the nodes' position (-1 = random)
debug	bool		debug switch
speed	double		speed of the host (in m/s)
updateInterval	double		time interval to update the hosts position (seconds)

Properties:

Name	Value	Description
display	i=block/cogwheel
class	ConstSpeedMobility
