Abstract

We develop Markov models for various schedulers in order to evaluate their performance tradeoffs at wireless links. While FIFO scheduling aggregates flows into a single flow just prior to the wireless link, channel-state dependent (or CSD) schedulers maintain a queue for each flow, and use predicted channel information to make scheduling decisions. We present results of tradeoffs in terms of overall throughput and per-flow QoS performance obtained with each scheduler under different channel conditions.
