Improve your USB experience with Wi-Fi through dynamic QoS adaptation

Conjunction of USB applications with wireless technologies leads us to USB over Wi-Fi through the means of Wireless Serial Extension (WSE). However, USB and Wi-Fi has distinct data prioritization methods, which causes problems in existing QoS protocols when the two technologies are used together. To solve this problem, this poster proposes and evaluates the dynamic QoS adaptation scheme, which intelligently maps the data of USB with the weighted transmission queues of enhanced distributed channel access (EDCA) mechanism.
