Ptr< UniformRandomVariable > m_direction
rv to control direction
Ptr< RandomVariableStream > m_speed
a random variable to control speed
void ResetDirectionAndSpeed(void)
Set a new direction and speed.
ConstantVelocityHelper m_helper
helper for velocity computations
virtual void DoInitialize(void)
Initialize() implementation.
void DoInitializePrivate(void)
Sets a new random direction and calls SetDirectionAndSpeed.
Utility class used to move node with constant velocity.
Keep track of the current position and velocity of an object.
virtual void DoSetPosition(const Vector &position)
virtual void DoDispose(void)
Destructor implementation.
virtual int64_t DoAssignStreams(int64_t)
The default implementation does nothing but return the passed-in parameter.
Every class exported by the ns3 library is enclosed in the ns3 namespace.
EventId m_event
event ID of next scheduled event
static TypeId GetTypeId(void)
Register this type with the TypeId system.
An identifier for simulation events.
Definition: event-id.h:53
void SetDirectionAndSpeed(double direction)
Set new velocity and direction, and schedule next pause event
Ptr< RandomVariableStream > m_pause
a random variable to control pause
void BeginPause(void)
Pause, cancel currently scheduled event, schedule end of pause event.
a unique identifier for an interface.
Definition: type-id.h:58
