  Energy harvesting communication has raised great research interests due to
its wide applications and feasibility of commercialization. In this paper, we
investigate the multiuser energy diversity. Specifically, we reveal the
throughput gain coming from the increase of total available energy harvested
over time/space and from the combined dynamics of batteries. Considering both
centralized and distributed access schemes, the scaling of the average
throughput over the number of transmitters is studied, along with the scaling
of corresponding available energy in the batteries.
