ns3::WifiHelper::WifiHelper | ( | ) |
Create a Wifi helper in an empty state: all its parameters must be set before calling ns3::WifiHelper::Install.
The default state is defined as being an Adhoc MAC layer with an ARF rate control algorithm and both objects using their default attribute values. By default, configure MAC and PHY for 802.11a.

int64_t ns3::WifiHelper::AssignStreams | ( | NetDeviceContainer | c, |

Assign a fixed random variable stream number to the random variables used by the PHY and MAC aspects of the Wifi models.
Each device in container c has fixed stream numbers assigned to its random variables. The Wifi channel (e.g. propagation loss model) is excluded. Return the number of streams (possibly zero) that have been assigned. The Install() method should have previously been called by the user.

standard | the PHY standard to configure during installation |
This method sets standards-compliant defaults for WifiMac parameters such as SIFS time, slot time, timeout values, etc., based on the standard selected. It results in WifiMac::ConfigureStandard(standard) being called on each installed MAC object.
The default standard of 802.11a will be applied if SetStandard() is not called.
Note that WifiMac::ConfigureStandard () will overwrite certain defaults in the attribute system, so if a user wants to manipulate any default values affected by ConfigureStandard() while using this helper, the user should use a post-install configuration such as Config::Set() on any objects that this helper creates, such as:
