| Abstract | In this paper, we consider the scheduling problem where datapackets fromK input flows need to be delivered to K corresponding wireless receivers over a heterogeneous wir eless channel. Our objective is to design a wireless scheduler that optimizes the buffer requirement at each wir eless receiver while maintaining good throughput performance. This is a challenging problem due to the uniquecharacteristics of the wireless channel. We propose a novel idea of exploiting both the long-term and s hort-term error behavior of the wireless channel in the scheduler design. In addition to typical first-order Quality of Service (QoS) metrics such as throughput and delay, our performance analysis of the scheduler permit s the evaluation of higher-order metrics, which are needed to evaluate the buffer requirement. We show that the p roposed scheduler achieves high overall throughput as well as low buffer requirement when compared to other wireless schedulers that only make use of the instantaneous channel state in a heterogenous channel. |
