Detailed Description

STAs communicate with each directly outside the context of a BSS

In OCB mac mode,synchronization, association, dis-association and authentication of normal wifi are not used for wireless access in vehicular environments.

Although Timing Advertisement frame is a specific management frame defined in 802.11p. It is mainly used by IEEE Std 1609.4 for channel switch synchronization. However in simulation nodes are supposed to have GPS synchronization ability, so we will not implement this feature.

◆ Receive()

void ns3::OcbWifiMac::Receive	(	Ptr< Packet >	packet,
		const WifiMacHeader *	hdr
	)

privatevirtual

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 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.

Parameters

packet	the packet that has been received.
hdr	a pointer to the MAC header of the received frame.

Reimplemented from ns3::RegularWifiMac.
