Method and apparatus for real time scheduling of traffic in wireless networks

摘要

A method for scheduling of traffic in wireless networks, whereas said network comprises real-time stations intending to send real-time traffic and best-effort stations sending best effort traffic, said method comprising:;transmitting by a primary real-time station periodically a real-time access marker to thereby define rounds;assigning a sequence number to each station in said network which intends to send real-time traffic;based on the sequence number assigned to a station, defining a fixed backoff time at which a packet from this station is transmitted after the start of a round to thereby establish a sequence in which the real-time packets are sent by the different realtime stations, said method being characterized by further comprising:overhearing for a predetermined period of time the traffic by a station which intends to send real-time traffic;if from said overhearing said station concludes that there is already a primary station transmitting real-time access markers, assuming by said station a sequence number based on the number of real-time stations which already are sending real-time traffic.
