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

Definition at line 292 of file regular-wifi-mac.h.

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

Parameters
packetthe packet that has been received.
fromthe MAC address of the device that sent the packet.
tothe MAC address ot the device that the packet is destined for.

void ns3::RegularWifiMac::DoDispose ( void  )
protectedvirtual

Destructor implementation.

This method is called by 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.

Initialize() implementation.

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.

Parameters
packetthe packet to send.

fromthe 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.

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.

void ns3::RegularWifiMac::Receive ( Ptr< Packet packet,

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
packetthe packet that has been received.
hdra pointer to the MAC header of the received frame.

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.
