Quantifying Bandwidth Gain of Triage QoS Protocol and Mobility Effects

In previous work we presented the Triage protocol, an end-to-end (E2E) QoS approach, where packet scheduling is biased by priority class, the severity of distress in meeting E2E QoS goals, and the likelihood of meeting those goals if service rates are altered. In this work, we present improvements t...

Description
Summary:In previous work we presented the Triage protocol, an end-to-end (E2E) QoS approach, where packet scheduling is biased by priority class, the severity of distress in meeting E2E QoS goals, and the likelihood of meeting those goals if service rates are altered. In this work, we present improvements to the heuristics used to determine the Triage distress in the per-hop behavior, simulation results showing a 22% bandwidth gain through use of the Triage QoS protocol. Finally, we also show that significant gains are obtained even under high mobility conditions
