Constructor & Destructor Documentation

cDatarateChannel ( const char * name = nullptr )

explicit

Constructor. This is only for internal purposes, and should not be used when creating channels dynamically; use the create() factory method instead.

virtual ~cDatarateChannel ( )

virtual

Destructor.

Member Function Documentation

virtual void handleParameterChange ( const char * parname )

overrideprotectedvirtual

This method is called by the simulation kernel to notify the module or channel that the value of an existing parameter has changed. Redefining this method allows simple modules and channels to be react on parameter changes, for example by re-reading the value. This default implementation does nothing.

The parameter name is nullptr if more than one parameter has changed.

To make it easier to write predictable components, the function is NOT called on uninitialized components (i.e. when initialized() returns false). For each component, the function is called (with nullptr as a parname) after the last stage of the initialization, so that the module gets a chance to update its cached parameters.

Also, one must be extremely careful when changing parameters from inside handleParameterChange(), to avoid creating an infinite notification loop.

Reimplemented from cComponent.

virtual void finish ( )

overrideprotectedvirtual

Finish hook. finish() is called after end of simulation if it terminated without error. This default implementation does nothing.

Reimplemented from cComponent.

static cDatarateChannel* create ( const char * name )

static

Utility function for dynamic channel creation. Equivalent to cChannelType::getDatarateChannelType()->create(name).

virtual std::string str ( ) const

overridevirtual

Produces a one-line description of the object's contents. See cObject for more details.

Reimplemented from cChannel.

virtual bool isTransmissionChannel ( ) const

inlineoverridevirtual

Returns true.

Implements cChannel.

virtual void setDelay ( double d )

virtual

Sets the propagation delay of the channel, in seconds.

virtual void setDatarate ( double d )

virtual

Sets the data rate of the channel, in bit/second.

See also: isBusy(), getTransmissionFinishTime()

virtual void setBitErrorRate ( double d )

virtual

Sets the bit error rate (BER) of the channel.

See also: cPacket::hasBitError()

virtual void setPacketErrorRate ( double d )

virtual

Sets the packet error rate (PER) of the channel.

See also: cPacket::hasBitError()

virtual void setDisabled ( bool d )

virtual

Disables or enables the channel.

virtual simtime_t getDelay ( ) const

inlinevirtual

Returns the propagation delay of the channel, in seconds. This method is equivalent to reading the "delay" parameter, via par("delay").

virtual double getDatarate ( ) const

inlinevirtual

Returns the data rate of the channel, in bit/second. This method is equivalent to reading the "datarate" parameter, via par("datarate"). This value affects the transmission time of messages sent through the channel.

virtual double getBitErrorRate ( ) const

inlinevirtual

Returns the bit error rate (BER) of the channel. This method is equivalent to reading the "ber" parameter, via par("ber"). When a message sent through the channel suffers at least one bit error, its bit error flag will be set.

virtual double getPacketErrorRate ( ) const

inlinevirtual

Returns the packet error rate (PER) of the channel. This method is equivalent to reading the "per" parameter, via par("per"). When a message is sent through the channel, its bit error flag will be set with this probability.

virtual bool isDisabled ( ) const

inlinevirtual

Returns whether the channel is disabled. This method is equivalent to reading the "disabled" parameter, via par("disabled"). A disabled channel discards all messages sent on it.

virtual double getNominalDatarate ( ) const

inlineoverridevirtual

Same as getDatarate().

Implements cChannel.

virtual simtime_t calculateDuration ( cMessage * msg ) const

overridevirtual

Returns the message length in bits divided by the datarate.

Note that processMessage() does NOT call this method, so in order to change the duration computation algorithm via subclassing you need to redefine both this and processMessage().

Implements cChannel.

virtual simtime_t getTransmissionFinishTime ( ) const

inlineoverridevirtual

Returns the simulation time the sender gate will finish transmitting. If the gate is not currently transmitting, the result is undefined but less or equal the current simulation time.

The transmission duration of a message depends on the message length and the data rate assigned to the channel.

Implements cChannel.

virtual bool isBusy ( ) const

inlineoverridevirtual

Returns whether the sender gate is currently transmitting, ie. whether transmissionFinishTime() is greater than the current simulation time.

Reimplemented from cChannel.

References omnetpp::simTime().

virtual void forceTransmissionFinishTime ( simtime_t t )

overridevirtual

Forcibly overwrites the finish time of the current transmission in the channel (see getTransmissionFinishTime()). This method can be used for implementing transmission abortion; see declaration in base class (cChannel::forceTransmissionFinishTime()) for more information.

Implements cChannel.

virtual void initialize ( )

overridevirtual

Initialization.

Reimplemented from cComponent.

virtual void processMessage	(	cMessage *	msg,
		simtime_t	t,
		result_t &	result
	)

overridevirtual

Performs bit error rate, delay and transmission time modelling.

Implements cChannel.
