an EUI-48 address
Definition: mac48-address.h:44
Smart pointer class similar to boost::intrusive_ptr.
Definition: ptr.h:74
Simulation virtual time values and global simulation resolution.

static Time Min()
Minimum representable Time Not to be confused with Min(Time,Time).
Definition: nstime.h:274
Implements the IEEE 802.11 MAC header.
This class stores the TX parameters (TX vector, protection mechanism, acknowledgment mechanism,...
void AggregateMsdu(Ptr< const WifiMacQueueItem > msdu)
Record that an MSDU is being aggregated to the last MPDU added to the frame that hase the same receiv...
void Clear(void)
Reset the TX parameters.
std::pair< uint32_t, uint32_t > GetSizeIfAggregateMsdu(Ptr< const WifiMacQueueItem > msdu) const
Get the size in bytes of the frame in case the given MSDU is aggregated.
const PsduInfoMap & GetPsduInfoMap(void) const
Get a const reference to the map containing information about PSDUs.
std::unique_ptr< WifiProtection > m_protection
protection method
WifiTxParameters & operator=(const WifiTxParameters &txParams)
Copy assignment operator.
uint32_t GetSize(Mac48Address receiver) const
Get the size in bytes of the (A-)MPDU addressed to the given receiver.
uint32_t GetSizeIfAddMpdu(Ptr< const WifiMacQueueItem > mpdu) const
Get the size in bytes of the frame in case the given MPDU is added.
std::unique_ptr< WifiAcknowledgment > m_acknowledgment
acknowledgment method
const PsduInfo * GetPsduInfo(Mac48Address receiver) const

Time m_txDuration
TX duration of the frame.
WifiTxVector m_txVector
TXVECTOR of the frame being prepared.
PsduInfoMap m_info
information about the frame being prepared.
void Print(std::ostream &os) const
Print the object contents.
void AddMpdu(Ptr< const WifiMacQueueItem > mpdu)
Record that an MPDU is being added to the current frame.
std::map< Mac48Address, PsduInfo > PsduInfoMap
Map containing information about the PSDUs addressed to every receiver.
This class mimics the TXVECTOR which is to be passed to the PHY in order to define the parameters whi...
Every class exported by the ns3 library is enclosed in the ns3 namespace.
std::ostream & operator<<(std::ostream &os, const Angles &a)
Definition: angles.cc:139
information about the frame being prepared for a specific receiver
std::map< uint8_t, std::set< uint16_t > > seqNumbers
set of the sequence numbers of the MPDUs added for each TID
uint32_t ampduSize
the size in bytes of the A-MPDU if multiple MPDUs have been added, and zero otherwise
WifiMacHeader header
MAC header of the last MPDU added.
uint32_t amsduSize
