In this paper, we aim to obtain the optimal delay-power tradeoff and the corresponding optimal scheduling policy for arbitrary i.i.d. arrival process and adaptive transmissions. The number of backlogged packets at the transmitter is known to a scheduler, who has to determine how many backlogged packets to transmit during each time slot. The power consumption is assumed to be convex in transmission...
Joint channel-aware and buffer-aware scheduling along with rate/power adaptation is a promising solution to assure Quality of Service (QoS) and improve energy efficiency. In this paper, an analytical delay-power tradeoff and optimal threshold-based scheduling are proposed. In particular, we are interested in the scheduling policies where the scheduler only needs to decide transmitting or not. More...
