Name	Type	Description
NonQosRecoveryProcedure	simple module	Implements frame retransmission and recovery procedures for non-QoS frames in IEEE 802.11 networks. Manages short and long retry counters, adjusts contention window size based on transmission outcomes, and enforces retry limits. Handles different retry procedures for frames below and above the RTS threshold as specified in IEEE 802.11 standard section 9.19.2.6.
