Energy-Efficient Scheduling over Fading Channels with Transmission Modulation and Deadline Constraints

This letter investigates the problem of energy-efficient scheduling over fading channels. Considering the practical constraints of transmission modulation and deadline, a more rigorous system model is described. Furthermore, the scheduling problem is formulated as a stochastic programming problem. Then, the stochastic programming problem can be solved by exploiting the idea of dynamic programming (DP) and two DP-based scheduling schemes are given. The numerical results show that the proposed optimization problem is more efficient at guiding the development of the scheduling schemes for energy-efficient scheduling. Moreover, the proposed scheduling schemes perform quite well in terms of quality and computational complexity.
