Abstract:

We consider packet transmission policies in the cross-layer perspective that minimize the average power consumed by the transmitter under the average delay constraints. We present a simple packet scheduling policy which is influenced by both the queue and the channel state and that can be utilized to trade-off characteristic between queueing delay and transmission power policy. The near-optimal scheduler adopts a low-complexity modified-linear-rule (MLR) which tends to make the queue evolve as a stable feed-back linear system. The parameter is chosen so as to reach the desired compromise between delay and power consumption. Throughout the extensive simulations, we generalize the scheme of MLR scheduler to the multiuser wireless fading environments and compare it with the performance of the optimal scheduler and the log-linear scheduler.
