Abstract

This paper presents a framework for provisioning application and channd dependent qu~ty of service in wirdess network-. The framework is based on three Merent adap tation me~anisms that operate over distinct adaptation time scd=. At the pa&et transmission time sc~e, channd prediction determines whether to transmit a packet or not depending on the state of the wird= channd. At the packet schedfig time scale, a channel state dependent schedder compensates flows that experience bad W qurdity wMe attempting to maintain minimum bandwidth G surances. The packet schedfig scheme is complemented by an app~cation-specitic adaptation mechanism that operates over longer time sc~es and takes into account the abdity of fidess app~cations to adapt to changes in adable bandwidth and channd conditions. U*e packet schedding, adaptation takea into account appKcation-levd semantiw and operates over time scales that can be programmed by USfl.

无线网络预测、补偿和自适应的系统方法

本文提出了一种无线网络中应用发放和信道相关业务分配的框架。该框架基于在不同适应时间内运行的三种瞬时适应机制。在pa&et传输时间sc~e，信道预测根据信道的状态决定是否传输数据包。在包调度时间尺度上，通道状态相关的调度程序补偿那些经历糟糕的流量(试图保持最小带宽保证)的流。数据包调度方案由特定于应用程序的自适应机制补充，该机制在更长的时间间隔内运行，并考虑到应用程序适应可调带宽和信道条件变化的能力。在数据包调度中，自适应考虑到应用级语义，并在USfl可编程的时间尺度上运行。
