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.

void ns3::MacLowTransmissionParameters::DisableNextData ( void   ) 

Do not attempt to send data burst after current transmission

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.

void ns3::MacLowTransmissionParameters::DisableRts ( void   ) 

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

void ns3::MacLowTransmissionParameters::EnableAck ( void   ) 

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

void ns3::MacLowTransmissionParameters::EnableFastAck ( void   ) 

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

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

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.

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

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.

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.

void ns3::MacLowTransmissionParameters::EnableSuperFastAck ( void   ) 

Time ns3::MacLowTransmissionParameters::GetDurationId ( void   )  const

the duration/id forced by EnableOverrideDurationId

uint32_t ns3::MacLowTransmissionParameters::GetNextPacketSize ( void   )  const

the size specified by EnableNextData.

bool ns3::MacLowTransmissionParameters::HasDurationId ( void   )  const

true if a duration/id was forced with EnableOverrideDurationId, false otherwise.

bool ns3::MacLowTransmissionParameters::HasNextPacket ( void   )  const

true if EnableNextData was called, false otherwise.

bool ns3::MacLowTransmissionParameters::MustSendRts ( void   )  const

true if RTS should be sent and CTS waited for before sending data, false otherwise.

bool ns3::MacLowTransmissionParameters::MustWaitAck ( void   )  const

true if must wait for ACK after data transmission, false otherwise.
This methods returns true when any of MustWaitNormalAck, MustWaitFastAck, or MustWaitSuperFastAck return true.

bool ns3::MacLowTransmissionParameters::MustWaitFastAck ( void   )  const

true if fast ack protocol should be used, false otherwise.

bool ns3::MacLowTransmissionParameters::MustWaitNormalAck ( void   )  const

true if normal ACK protocol should be used, false otherwise.
See also:

bool ns3::MacLowTransmissionParameters::MustWaitSuperFastAck ( void   )  const

true if super fast ack protocol should be used, false otherwise.
