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.

void ns3::MacLowTransmissionParameters::DisableAck ( void )

Do not wait for Ack after data transmission.

Typically used for Broadcast and multicast frames.

Wait ACKTimeout for an ACK.

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

Here is the caller graph for this function:

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.

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::StartNextFragment at the end of the current transmission + SIFS.
