Detailed Description

Basic MAC of mesh point Wi-Fi interface. Its function is extendable through plugins mechanism.

Now only three output queues are used:

beacons (PIFS and no backoff),
background traffic,
management and priority traffic.

Here is the call graph for this function:

void ns3::MeshWifiInterfaceMac::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.

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

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.
