Abstract (EN): In this paper, a new traffic separation mechanism is proposed for IEEE 802.11e networks. Such Traffic Separation Mechanism (TSm) allows the coexistence of CSMA standard stations with modified (real-time) stations in the same network domain. A station implementing the proposed TSm scheme has the same operating behavior as a standard IEEE 802.11e network station, except in what concerns the evaluation of the backoff delay. For the case of stations implementing the TSm scheme, whenever they have traffic to transfer, they eventually impose its transfer prior to the transfer of any other message with lower priority. This behavior guarantees the highest transmitting probability to the TSm stations in an open communication environment, where multiple IEEE 802.11e standard stations may coexist with a subset of TSm-enabled real-time stations.
