TxopProcedure¶

Package: inet.linklayer.ieee80211.mac.originator

simple module TxopProcedure

Implements the Transmission Opportunity (TXOP) mechanism in IEEE 802.11 QoS networks. Manages TXOP periods during which a station has the right to transmit. Tracks TXOP limits based on access category (AC) and PHY mode. Supports both single and multiple protection mechanisms to protect frame exchanges during the TXOP.
