The existing distributed QoS mechanisms for WLAN MAC layer are only able to differentiate between various traffic streams without being able to guarantee QoS On the other hand, most of the centralized QoS mechanisms are only able to guarantee QoS parameters for CBR traffic effectively This paper addresses these deficiencies by proposing a new distributed QoS scheme that guarantees QoS parameters such as delay and throughput for both CBR and VBR traffics The proposed scheme can also adapt to the various conditions of the network To achieve this, three fields are added to the RTS/CTS frames that their combination with the previously existing duration field of RTS/CTS frames, guarantees the periodic access of a station to the channel The performance of the proposed method has been evaluated with a specific simulator The result are compared with IEEE 802.11e HCCA mechanism, and shown that it outperforms HCCA.
