Detailed Description

base class for all MAC-level wifi objects.

This class encapsulates all the low-level MAC functionality DCA, EDCA, etc) and all the high-level MAC functionality (association/disassociation state machines).

Member Typedef Documentation

typedef std::map<AcIndex, Ptr<EdcaTxopN> > ns3::RegularWifiMac::EdcaQueues [protected]

This type defines a mapping between an Access Category index, and a pointer to the corresponding channel access function

typedef Callback<void, Ptr<Packet>, Mac48Address, Mac48Address> ns3::RegularWifiMac::ForwardUpCallback

This type defines the callback of a higher layer that a WifiMac(-derived) object invokes to pass a packet up the stack.

Parameters:

	packet	the packet that has been received.
	from	the MAC address of the device that sent the packet.
	to	the MAC address ot the device that the packet is destined for.

---

Member Function Documentation

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

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.

virtual void ns3::RegularWifiMac::DoDispose

(

)

[protected, virtual]

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.

virtual void ns3::RegularWifiMac::DoStart

(

)

[protected, virtual]

This method is called only once by Object::Start. If the user calls Object::Start multiple times, DoStart 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.

Reimplemented from ns3::Object.

virtual void ns3::RegularWifiMac::Enqueue	(	Ptr< const Packet >	packet,
		Mac48Address	to
	)			[pure virtual]

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.

Implements ns3::WifiMac.

Implemented in ns3::MeshWifiInterfaceMac, ns3::AdhocWifiMac, ns3::ApWifiMac, and ns3::StaWifiMac.

virtual void ns3::RegularWifiMac::Enqueue	(	Ptr< const Packet >	packet,
		Mac48Address	to,
		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.

Implements ns3::WifiMac.

Reimplemented in ns3::MeshWifiInterfaceMac, and ns3::ApWifiMac.

virtual void ns3::RegularWifiMac::FinishConfigureStandard

(

enum WifiPhyStandard

standard

)

[protected, virtual]

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.

Implements ns3::WifiMac.

Reimplemented in ns3::MeshWifiInterfaceMac.

virtual Ptr<WifiPhy> ns3::RegularWifiMac::GetWifiPhy

virtual void ns3::RegularWifiMac::Receive	(	Ptr< Packet >	packet,
		const WifiMacHeader *	hdr
	)			[protected, virtual]

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.

virtual void ns3::RegularWifiMac::SendAddBaResponse	(	const MgtAddBaRequestHeader *	reqHdr,
		Mac48Address	originator
	)			[protected, virtual]

This method can be called to accept a received ADDBA Request. An ADDBA Response will be constructed and queued for transmission.

Parameters:

	reqHdr	a pointer to the received ADDBA Request header.
	originator	the MAC address of the originator.

Implements ns3::WifiMac.

Reimplemented in ns3::MeshWifiInterfaceMac, ns3::AdhocWifiMac, and ns3::ApWifiMac.

void ns3::RegularWifiMac::SetPifs

(

Time

pifs

)

[virtual]

Parameters:

pifs

the pifs duration.

Implements ns3::WifiMac.

void ns3::RegularWifiMac::SetQosSupported

(

bool

enable

)

[protected]

Set accessor for the m_qosSupported member

void ns3::RegularWifiMac::SetSifs

(

Time

sifs

)

[virtual]

Parameters:

sifs

the sifs duration

Implements ns3::WifiMac.

void ns3::RegularWifiMac::SetSlot

(

Time

slotTime

)

[virtual]

Parameters:

slotTime

the slot duration

Implements ns3::WifiMac.

virtual void ns3::RegularWifiMac::SetSsid

(

Ssid

ssid

)

[virtual]

Parameters:

ssid

the current ssid of this MAC layer.

Implements ns3::WifiMac.

void ns3::RegularWifiMac::SetTypeOfStation

(

TypeOfStation

type

)

[protected]

This method is invoked by a subclass to specify what type of station it is implementing. This is something that the channel access functions (instantiated within this class as EdcaTxopN's) need to know.

Parameters:

type

the type of station.

virtual void ns3::RegularWifiMac::SetWifiPhy

(

Ptr< WifiPhy >

phy

)

[virtual]

Parameters:

phy

the physical layer attached to this MAC.

Implements ns3::WifiMac.

virtual void ns3::RegularWifiMac::SetWifiRemoteStationManager

(

Ptr< WifiRemoteStationManager >

stationManager

)

[virtual]

Parameters:

stationManager

the station manager attached to this MAC.

Implements ns3::WifiMac.

Reimplemented in ns3::ApWifiMac.

Member Data Documentation

Ptr<DcaTxop> ns3::RegularWifiMac::m_dca [protected]

This holds a pointer to the DCF instance for this WifiMac - used for transmission of frames to non-QoS peers.

EdcaQueues ns3::RegularWifiMac::m_edca [protected]

This is a map from Access Category index to the corresponding channel access function

bool ns3::RegularWifiMac::m_qosSupported [protected]

This Boolean is set true iff this WifiMac is to model 802.11e/WMM style Quality of Service. It is exposed through the attribute system.

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