virtual void | DoDispose (void) |
Hold together all Wifi-related objects.
This class holds together ns3::WifiChannel, ns3::WifiPhy, ns3::WifiMac, and, ns3::WifiRemoteStationManager.
virtual void ns3::WifiNetDevice::DoDispose | ( | void | ) | [private, virtual] |
This method is called by Object::Dispose or by the object's destructor, whichever comes first.
Subclasses are expected to implement their real destruction code in an overriden 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.
Reimplemented from ns3::Object.

Implements ns3::NetDevice.
virtual Address ns3::WifiNetDevice::GetMulticast | ( | void | ) | const [virtual] |
Return the MAC multicast base address used when mapping multicast groups to MAC multicast addresses.
Typically when one constructs a multicast MAC addresses, some bits from the IP multicast group are copied into a corresponding MAC multicast group. In EUI-48, for example, the low order 23 bits of the multicast group are copied to the MAC multicast group base address.
This method allows access to the underlying MAC multicast group base address. It is expected that in most cases, a net device client will allow the net device to perform the actual construction of the multicast address. Use of this method is discouraged unless you have a good reason to perform a custom mapping. You should prefer NetDevice::MakeMulticastAddress which will do the RFC-specified mapping for the net device in question.

virtual Address ns3::WifiNetDevice::MakeMulticastAddress | ( | Ipv4Address | multicastGroup | ) | const [virtual] |
Make and return a MAC multicast address using the provided multicast group.
RFC 1112 says that an Ipv4 host group address is mapped to an Ethernet multicast address by placing the low-order 23-bits of the IP address into the low-order 23 bits of the Ethernet multicast address 01-00-5E-00-00-00 (hex). Similar RFCs exist for Ipv6 and Eui64 mappings. This method performs the multicast address creation function appropriate to the underlying MAC address of the device. This MAC address is encapsulated in an abstract Address to avoid dependencies on the exact MAC address format.
A default imlementation of MakeMulticastAddress is provided, but this method simply NS_ASSERTS. In the case of net devices that do not support multicast, clients are expected to test NetDevice::IsMulticast and avoid attempting to map multicast packets. Subclasses of NetDevice that do support multicasting are expected to override this method and provide an implementation appropriate to the particular device.
