Detailed Description

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.

bool ns3::RraaWifiManager::DoNeedRts ( WifiRemoteStation station,
Ptr< const Packet packet,
bool  normally 
)
privatevirtual
Parameters
stationthe station that we need to communicate
packetthe packet to send
normallyindicates whether the normal 802.11 rts enable mechanism would request that the rts is sent or not.
Returns
true if we want to use an RTS/CTS handshake for this packet before sending it, false otherwise.

Note: This method is called before a unicast packet is sent on the medium.
