uint8_t GetInformationFieldSize() const
Get information field size function.
bool m_dsssSupported
This is used to decide whether this element should be added to the frame or not.

#define NS_ASSERT(condition)
At runtime, in debugging builds, if this condition is not true, the program prints the source file...
Definition: assert.h:67
uint16_t GetSerializedSize() const
Return the serialized size of this DSSS Parameter Set.
uint16_t GetSerializedSize() const
Get the size of the serialized IE including Element ID and length fields.
iterator in a Buffer instance
Definition: buffer.h:98
WifiInformationElementId ElementId() const
Element ID function.
uint8_t DeserializeInformationField(Buffer::Iterator start, uint8_t length)
Deserialize infornamtion field function.
void SerializeInformationField(Buffer::Iterator start) const
Serialize information field function.
#define IE_DSSS_PARAMETER_SET
void SetCurrentChannel(uint8_t currentChannel)
Set the Current Channel field in the DsssParameterSet information element.
Every class exported by the ns3 library is enclosed in the ns3 namespace.
void SetDsssSupported(uint8_t DsssSupported)
Set DSSS supported.
void WriteU8(uint8_t data)
Definition: buffer.h:869
uint8_t m_currentChannel

uint8_t WifiInformationElementId
This type is used to represent an Information Element ID.
Buffer::Iterator Serialize(Buffer::Iterator i) const
Serialize entire IE including Element ID and length fields.
Buffer::Iterator Serialize(Buffer::Iterator start) const
This information element is a bit special in that it is only included if the STA does support DSSS...
