Member Function Documentation

void ns3::RegularWifiMac::DeaggregateAmsduAndForward	(	Ptr< Packet >	aggregatedPacket,
		const WifiMacHeader *	hdr
	)

protectedvirtual

This method can be called to de-aggregate an A-MSDU and forward the constituent packets up the stack.

Parameters

aggregatedPacket	the Packet containing the A-MSDU.
hdr	a pointer to the MAC header for `aggregatedPacket`.

Here is the caller graph for this function:

void ns3::RegularWifiMac::DoDispose ( void )

protectedvirtual

This method is called by Object::Dispose or by the object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overriden version of this method and chain up to their parent's implementation once they are done. i.e., for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose method.

It is safe to call GetObject from within this method.

Reimplemented from ns3::Object.

void ns3::RegularWifiMac::DoInitialize ( void )

protectedvirtual

This method is called only once by Object::Initialize. If the user calls Object::Initialize multiple times, DoInitialize is called only the first time.

Subclasses are expected to override this method and chain up to their parent's implementation once they are done. It is safe to call GetObject and AggregateObject from within this method.

void ns3::RegularWifiMac::Enqueue	(	Ptr< const Packet >	packet,

		Mac48Address	from
	)

virtual

Parameters

packet	the packet to send.
to	the address to which the packet should be sent.
from	the address from which the packet should be sent.

The packet should be enqueued in a tx queue, and should be dequeued as soon as the channel access function determines that access is granted to this MAC. The extra parameter "from" allows this device to operate in a bridged mode, forwarding received frames without altering the source address.

Parameters

packet	the packet to send.
to	the address to which the packet should be sent.

The packet should be enqueued in a tx queue, and should be dequeued as soon as the channel access function determines that access is granted to this MAC.

void ns3::RegularWifiMac::FinishConfigureStandard ( enum WifiPhyStandard standard )

protectedvirtual

Parameters

standard the phy standard to be used

This method is called by ns3::WifiMac::ConfigureStandard to complete the configuration process for a requested phy standard.

This method may be overriden by a derived class (e.g., in order to apply DCF or EDCA parameters specific to the usage model it is dealing with), in which case the reimplementation may choose to deal with certain values in the WifiPhyStandard enumeration, and chain up to this implementation to deal with the remainder.

protectedvirtual

This method acts as the MacRxMiddle receive callback and is invoked to notify us that a frame has been received. The implementation is intended to capture logic that is going to be common to all (or most) derived classes. Specifically, handling of Block Ack managment frames is dealt with here.

This method will need, however, to be overriden by derived classes so that they can perform their data handling before invoking the base version.

Parameters

packet	the packet that has been received.
hdr	a pointer to the MAC header of the received frame.

This Boolean is set true iff this WifiMac is to model 802.11n. It is exposed through the attribute system.

At the moment, this flag is the sole selection between HT and non-HT operation for the STA (whether IBSS, AP, or non-AP). Ultimately, we will want a HT-enabled STA to be able to fall back to non-HT operation with a non-HT peer. This'll require further intelligence - i.e., per-association HT state. Having a big switch seems like a good intermediate stage, however.
