Patent number: 11343854Abstract: A novel method that dynamically changes the contention window of access points based on system load to improve performance in a dense Wi-Fi deployment is disclosed. A key feature is that no MAC protocol changes, nor client side modifications are needed to deploy the solution. Setting an optimal contention window can lead to throughput and latency improvements up to 155%, and 50%, respectively. Furthermore, an online learning method that efficiently finds the optimal contention window with minimal training data, and yields an average improvement in throughput of 53-55% during congested periods for a real traffic-volume workload replay in a Wi-Fi test-bed is demonstrated.Type: GrantFiled: July 31, 2020Date of Patent: May 24, 2022Assignee: Cable Television Laboratories, Inc.Inventors: Thomas Sandholm, Belal Hamzeh, Bernardo Huberman
