Energy-efficient transmission of delay-limited bursty data packets under non-ideal circuit power consumption

This paper develops a novel approach to energy-efficient transmission schedule for delay-limited bursty data arrivals under non-ideal circuit power consumption. Assuming aprior knowledge of packet arrivals and deadlines, an efficient algorithm is proposed to find the optimal policy that minimizes the total energy consumption, with a low computational complexity. It is revealed that the optimal data departure for the general nonideal circuit-power case can be obtained by simply adjusting the ideal-case data departure in accordance to an energy efficiency (EE) maximizing rate value. The proposed approach provides optimal benchmark for all the practical schemes, and can be employed to develop efficient online scheduling schemes which assume only causal knowledge of the data arrival and deadline realizations.
