Time GetDelay(Ptr< MobilityModel > a, Ptr< MobilityModel > b) const override
static TypeId GetTypeId(void)
Get the type ID.
int64_t DoAssignStreams(int64_t stream) override
Assign a fixed random variable stream number to the random variables used by this model.
ConstantSpeedPropagationDelayModel()
Use the default parameters from PropagationDelayConstantSpeed.
A base class which provides memory management and object aggregation.
Definition: object.h:88
calculate a propagation delay.
virtual int64_t DoAssignStreams(int64_t stream)=0
Assign a fixed random variable stream number to the random variables used by this model.
int64_t AssignStreams(int64_t stream)
If this delay model uses objects of type RandomVariableStream, set the stream numbers to the integers...
static TypeId GetTypeId(void)
Get the type ID.
virtual Time GetDelay(Ptr< MobilityModel > a, Ptr< MobilityModel > b) const =0
the propagation delay is random
RandomPropagationDelayModel()
Use the default parameters from PropagationDelayRandomDistribution.
Ptr< RandomVariableStream > m_variable
random generator
int64_t DoAssignStreams(int64_t stream) override
Assign a fixed random variable stream number to the random variables used by this model.
static TypeId GetTypeId(void)
Get the type ID.
Time GetDelay(Ptr< MobilityModel > a, Ptr< MobilityModel > b) const override
Simulation virtual time values and global simulation resolution.
Definition: nstime.h:104
a unique identifier for an interface.
Definition: type-id.h:59
Every class exported by the ns3 library is enclosed in the ns3 namespace.
