摘要：A method provides differentiated quality of service (QoS) by providing adaptiveupdates to media access control (MAC) layer parameters on a distributed basis. Themethod includes calculating a failure probability for a transmission over the network,determining a target value for determining a contention window according to a mappedfunction of the failure probability, and altering the contention window according to ascaling function of the target value. The mapped function and the scaling can provideQoS differentiation. A wireless device ensures fairness in a wireless time slotted networkand includes a network interface card (NIC), a network driver interface, a networkmonitor, a statistics engine, and an adaptive parameter engine for determining a targetvalue for determining a contention window according to a mapped function of the one ormore probabilities to enable an alteration of the contention window and provide newparameters for the MAC layer.
