Robust Rate Adaptation Algorithm
This is an implementation of RRAA as described in "Robust rate adaptation for 802.11 wireless networks" by "Starsky H. Y. Wong", "Hao Yang", "Songwu Lu", and, "Vaduvur Bharghavan" published in Mobicom 06.
This RAA does not support HT, VHT nor HE modes and will error exit if the user tries to configure this RAA with a Wi-Fi MAC that has VhtSupported, HtSupported or HeSupported set.
ns3::RraaWifiManager is accessible through the following paths with Config::Set and Config::Connect:
Size of this type is 416 bytes (on a 64-bit architecture).
