In this study, we investigate the energy scheduling problem for wireless communication with energy
harvesting devices. We consider wireless transmission systems equipped with energy harvesting devices, which
can provide sustainable energy to substitute traditional battery. One of challenging in the system is to efficiently
schedule energy consumption to maximize the utility and to adapt to the energy harvesting process. In general,
it is difficult to obtain the accurate energy harvesting model parameters. On the other hand, model errors could
considerably deteriorate the performances of traditional energy management approaches. We therefore consider
robust energy scheduling schemes under the model uncertainty of the energy harvesting process. The problem
is formulated as a robust Markov decision process and efficiently solved by robust dynamic programming.
Extensive simulation results verify our proposed approaches.
Key words: Energy harvesting, energy scheduling, robust markov decision process, wireless communication, , ,
