Detailed Description

control how a packet is transmitted.

The ns3::MacLow::StartTransmission method expects an instance of this class to describe how the packet should be transmitted.

Member Function Documentation

void ns3::MacLowTransmissionParameters::DisableAck ( void )

Do not wait for Ack after data transmission. Typically used for Broadcast and multicast frames.

Definition at line 133 of file mac-low.cc.

void ns3::MacLowTransmissionParameters::DisableNextData ( void )

Do not attempt to send data burst after current transmission

Definition at line 88 of file mac-low.cc.

void ns3::MacLowTransmissionParameters::DisableOverrideDurationId ( void )

Do not force the duration/id field of the packet: its value is automatically calculated by the MacLow before calling WifiPhy::Send.

Definition at line 98 of file mac-low.cc.

References ns3::Seconds().

void ns3::MacLowTransmissionParameters::DisableRts ( void )

Do not send rts and wait for cts before sending data.

Definition at line 143 of file mac-low.cc.

void ns3::MacLowTransmissionParameters::EnableAck ( void )

Wait ACKTimeout for an ACK. If we get an ACK on time, call MacLowTransmissionListener::GotAck. Call MacLowTransmissionListener::MissedAck otherwise.

Definition at line 128 of file mac-low.cc.

void ns3::MacLowTransmissionParameters::EnableBasicBlockAck ( void )

Wait BASICBLOCKACKTimeout for a Basic Block Ack Response frame.

Definition at line 108 of file mac-low.cc.

void ns3::MacLowTransmissionParameters::EnableCompressedBlockAck ( void )

Wait COMPRESSEDBLOCKACKTimeout for a Compressed Block Ack Response frame.

Definition at line 113 of file mac-low.cc.

void ns3::MacLowTransmissionParameters::EnableFastAck ( void )

wait PIFS after end-of-tx. If idle, call MacLowTransmissionListener::MissedAck.
if busy at end-of-tx+PIFS, wait end-of-rx
if Ack ok at end-of-rx, call MacLowTransmissionListener::GotAck.
if Ack not ok at end-of-rx, report call MacLowTransmissionListener::MissedAck at end-of-rx+SIFS.

This is really complicated but it is needed for proper HCCA support.

Definition at line 123 of file mac-low.cc.

void ns3::MacLowTransmissionParameters::EnableMultiTidBlockAck ( void )

NOT IMPLEMENTED FOR NOW

Definition at line 118 of file mac-low.cc.

void ns3::MacLowTransmissionParameters::EnableNextData ( uint32_t size )

Parameters

size	size of next data to send after current packet is sent.

Add the transmission duration of the next data to the durationId of the outgoing packet and call MacLowTransmissionListener::StartNext at the end of the current transmission + SIFS.

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

void ns3::MacLowTransmissionParameters::EnableOverrideDurationId ( Time durationId )

Parameters

durationId the value to set in the duration/Id field of the outgoing packet.

Ignore all other durationId calculation and simply force the packet's durationId field to this value.

Definition at line 93 of file mac-low.cc.

void ns3::MacLowTransmissionParameters::EnableRts ( void )

Send a RTS, and wait CTSTimeout for a CTS. If we get a CTS on time, call MacLowTransmissionListener::GotCts and send data. Otherwise, call MacLowTransmissionListener::MissedCts and do not send data.

Definition at line 138 of file mac-low.cc.

void ns3::MacLowTransmissionParameters::EnableSuperFastAck ( void )
