Member Function Documentation

virtual void ns3::MacLowAggregationCapableTransmissionListener::BlockAckInactivityTimeout	(	Mac48Address	originator,
		uint8_t	tid
	)

pure virtual

Typically is called in order to notify EdcaTxopN that a block ack inactivity timeout occurs for the block ack agreement identified by the pair originator, tid.

Rx station maintains an inactivity timer for each block ack agreement. Timer is reset when a frame with ack policy block ack or a block ack request are received. When this timer reaches zero this method is called and a delba frame is scheduled for transmission.

Parameters

originator	MAC address of the data originator
tid

Implemented in ns3::EdcaTxopN::AggregationCapableTransmissionListener.

Referenced by ns3::MacLow::CreateBlockAckAgreement(), and ns3::MacLow::ResetBlockAckInactivityTimerIfNeeded().

Here is the caller graph for this function:

void ns3::MacLowAggregationCapableTransmissionListener::CompleteMpduTx	(	Ptr< const Packet >	packet,
		WifiMacHeader	hdr,
		Time	tstamp
	)

virtual

This function stores an MPDU (part of an A-MPDU) in blockackagreement (i.e.

the sender is waiting for a blockack containing the sequence number of this MPDU). It also calls NotifyMpdu transmission that updates the status of OriginatorBlockAckAgreement.

Reimplemented in ns3::EdcaTxopN::AggregationCapableTransmissionListener.

Definition at line 83 of file mac-low.cc.

void ns3::MacLowAggregationCapableTransmissionListener::CompleteTransfer	(	Mac48Address	address,
		uint8_t	tid
	)

virtual

Parameters

address	address of peer station involved in block ack mechanism.
tid	traffic ID of transmitted packet.

Calls CompleteAmpduTransfer that resets the status of OriginatorBlockAckAgreement after the transfer of an A-MPDU with ImmediateBlockAck policy (i.e. no BAR is scheduled)

Reimplemented in ns3::EdcaTxopN::AggregationCapableTransmissionListener.

Definition at line 79 of file mac-low.cc.

virtual bool ns3::MacLowAggregationCapableTransmissionListener::GetBlockAckAgreementExists	(	Mac48Address	address,
		uint8_t	tid
	)

pure virtual

Parameters

recipient	address of the peer station
tid	traffic ID.

Returns: true if a block ack agreement exists, false otherwise

Checks if a block ack agreement exists with station addressed by recipient for tid tid.

Implemented in ns3::EdcaTxopN::AggregationCapableTransmissionListener.
