Collision avoidance for traffic in a wireless network

摘要

Techniques for avoiding collision of traffic in a wireless network are described. A station detects for synchronization of its traffic with traffic of other stations. The station may detect for synchronization based on, e.g., percentage of first transmission failures, counters indicative of statistics of transmitted frames, and/or other information. The station may confirm synchronization of its traffic, e.g., by monitoring for traffic from another station during a service period for the station. The station adjusts transmission of its traffic when synchronization is detected to avoid collision with the traffic of the other stations. The station may delay transmission of its traffic by a predetermined amount of time, by a pseudo-random amount, or until after the other stations finish their transmissions.

主权项

1. An apparatus comprising:
at least one processor configured to detect for synchronization of traffic of a station with traffic of at least one other station in a wireless network using a metric based on a function of a number of frames successfully sent with at least one retransmission, and to adjust transmission of the traffic of the station when synchronization is detected by shifting service times by a predetermined or pseudo-random amount of time to avoid collision with the traffic of the at least one other station; and a memory coupled to the at least one processor.
