Inheritance diagram for RfidTagPhy:


Public Types
typedef boost::shared_ptr< RfidTagPhy >	RfidTagPhyPtr
	Smart pointer that clients should use.
Public Member Functions
virtual	~RfidTagPhy ()
	A destructor A virtual destructor is recommended since the class has virtual functions.
RfidTagPhyPtr	thisRfidTagPhy ()
	Gives `this` pointer as a `RfidTagPhy` object.
virtual PhysicalLayerPtr	thisPhysicalLayer ()
	Gives `this` pointer as a `PhysicalLayer` object.

Static Public Member Functions
static RfidTagPhyPtr	create (NodePtr node, WirelessChannelManagerPtr wirelessChannelManager)
	A factory method to ensure that all objects are created via `new` since we are using smart pointers.

Member Function Documentation

void RfidTagPhy::recvdErrorFreeSignal	(	WirelessCommSignalPtr	signal,
		double	recvdSignalStrength
	)			`[virtual]`

This function is called when an error free signal is received, just before its packet is passed to the upper layer.

The transmit power is set to the received power of the signal since the tag reflects the power back to the reader.

Parameters:

	signal	the signal that was successfully received.
	recvdSignalStrength	the strength of the signal at the receiver.

Reimplemented from PhysicalLayer.

void RfidTagPhy::resetAllListenersChannel ( )

Invalidate the current all listeners channel.

After calling this function, the tag is no longer listening to any channels.

void RfidTagPhy::resetSendingChannel ( )

Invalidate the current sending channel.

After calling this function, the tag is no longer sending to any channels.

bool RfidTagPhy::setAllListenersChannel ( t_uint channelId )

Set the channel on which this (and, presumably, all) tags are listening on.

All tags should be set to listen on this channel, though they will send on a different channel where not necessarily all tags are sending.

Parameters:

channelId

the ID of the channel on which the tags will listen.

Returns:: true if the object is attached to the channel successfully.

bool RfidTagPhy::setSendingChannel ( t_uint channelId )

Set the sending for the RFID tag.

This corresponds to setting the channel on which the tag is sending since we model the tags's listening channel as being on which all tags listeng and all readers transmit on.

Parameters:

channelId

the ID of the channel on which the RFID tag will transmit.
