Simple Module TractorMobility

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

Moves a tractor through a field with a certain amount of rows. Since the tractor also moves around the field, the tractor travels the number of rows PLUS one rows. Consider the following piece of ascii-art for rows=2.

>>>>>>>>>>>>>>>v ^ v ^ v <<<<<<<<<<<<<<<< v ^ v ^ >>>>>>>>>>>>>>>^

NOTE: Does not yet support 3-dimensional movement.

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
x1	double		rectangle is denoted by the (x1,y1) and (x2,y2) coords [m]
y1	double		rectangle is denoted by the (x1,y1) and (x2,y2) coords [m]
x2	double		rectangle is denoted by the (x1,y1) and (x2,y2) coords [m]
y2	double		rectangle is denoted by the (x1,y1) and (x2,y2) coords [m]
rows	double		the number of rows the field is divided in
speed	double		speed of the host (in m/s)
updateInterval	double		time interval to update the hosts position (in seconds)

Properties:

Name	Value	Description
display	i=block/cogwheel
class	TractorMobility
