Return true if packets can be forwarded to the given destination, false otherwise.

to	the address to which the packet should be sent

Returns: whether packets can be forwarded to the given destination

◆ DoCompleteConfig()

void ns3::AdhocWifiMac::DoCompleteConfig ( )

Allow subclasses to complete the configuration of the MAC layer components.

Implements ns3::WifiMac.

◆ Enqueue()

void ns3::AdhocWifiMac::Enqueue	(	Ptr< WifiMpdu >	mpdu,

Parameters

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

Subclasses need to implement this method to finalize the MAC header of the MPDU (MAC addresses and ToDS/FromDS flags) and enqueue the MPDU in a TX queue.

Here is the call graph for this function:

◆ Receive()

void ns3::AdhocWifiMac::Receive	(	Ptr< const WifiMpdu >	mpdu,
		uint8_t	linkId )

overrideprivatevirtual

This method acts as the MacRxMiddle receive callback and is invoked to notify us that a frame has been received on the given link.

The implementation is intended to capture logic that is going to be common to all (or most) derived classes. Specifically, handling of Block Ack management frames is dealt with here.

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

The given link may be undefined in some cases (e.g., in case of QoS Data frames received in the context of a Block Ack agreement – because the BlockAckManager does not have to record the link each buffered MPDU has been received on); in such a cases, the value of linkId should be WIFI_LINKID_UNDEFINED.

Parameters

mpdu	the MPDU that has been received.
linkId	the ID of the given link
