void ns3::dot11s::IePreq::AddDestinationAddressElement ( bool  doFlag,
bool  rfFlag,
Mac48Address  dest_address,

)

Add a destination address unit: flags, destination and sequence number

void ns3::dot11s::IePreq::DecrementTtl ( )

Handle TTL and Metric:

uint8_t ns3::dot11s::IePreq::DeserializeInformationField ( Buffer::Iterator  start,
uint8_t  length 
)
virtual

Deserialize information (i.e., the body of the IE, not including the Element ID and length octets)

Implements ns3::WifiInformationElement.

uint8_t ns3::dot11s::IePreq::GetInformationFieldSize ( ) const
virtual

Length of serialized information (i.e., the length of the body of the IE, not including the Element ID and length octets. This is the value that will appear in the second octet of the entire IE - the length field)

Implements ns3::WifiInformationElement.

void ns3::dot11s::IePreq::Print ( std::ostream &  os) const
virtual

In addition, a subclass may optionally override the following...

Generate human-readable form of IE

Reimplemented from ns3::WifiInformationElement.
