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.

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.

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 managment frames is dealt with here.

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

Parameters
packetthe packet that has been received.
hdra pointer to the MAC header of the received frame.
