Detailed Description

OBSS PD algorithm interface.

Introspection did not find any typical Config paths.

This object provides the interface for all OBSS_PD algorithms and is designed to be subclassed.

OBSS_PD stands for Overlapping Basic Service Set Preamble-Detection. OBSS_PD is an 802.11ax feature that allows a STA, under specific conditions, to ignore an inter-BSS PPDU.

◆ ConnectWifiNetDevice()

void ns3::ObssPdAlgorithm::ConnectWifiNetDevice ( const Ptr< WifiNetDevice device)
virtual

Connect the WifiNetDevice and setup eventual callbacks.

Parameters

◆ DoDispose()

void ns3::ObssPdAlgorithm::DoDispose ( )
overrideprotectedvirtual

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 overridden 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.
