Name	Type	Description
QosRecoveryProcedure	simple module	Implements frame retransmission and recovery procedures for QoS frames in IEEE 802.11 networks. Manages retry counters for failed transmissions, adjusts contention window size, and enforces retry limits. Maintains separate short and long retry counters based on frame size relative to RTS threshold, and tracks per-TID frame status to support Quality of Service requirements.
