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 Function Documentation

virtual void ns3::WifiMac::Enqueue	(	Ptr< const Packet >	packet,
		Mac48Address	to,
		Mac48Address	from
	)			`[private, pure 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 DCF function determines that access it granted to this MAC. The extra parameter "from" allows this device to operate in a bridged mode, forwarding received frames without altering the source addresss.

Implemented in ns3::AdhocWifiMac, ns3::NqapWifiMac, and ns3::NqstaWifiMac.

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

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

Implemented in ns3::AdhocWifiMac, ns3::NqapWifiMac, and ns3::NqstaWifiMac.
