For wireless channels, interference mitigation techniques are typically applied at the packet transmission level. In this paper, we present the Havana Framework for supporting integrated adaptive-QOS that also responds to impairments over multiple time scales that are present at the flow/session level. Our framework is based on three different mechanisms that operate over distinct adaptation time scales. At the packet transmission time scale, a channel predictor determines whether to transmit a packet or not depending on the state of the wireless channel. At the packet scheduling time scale, a compensator credits and compensates flows that experience bad link quality. Over even longer time scales an adapter regulates flows taking into account the ability of wireless applications to adapt to changes in available bandwidth and channel conditions.
