This paper considers the design of online power
allocation strategies for slotted energy harvesting point-to-point
communications systems. The objective is to minimize the competitive
rate gap that is defined as the maximum gap between
the optimal rates that can be achieved by the offline and online
policies over all possible energy arrival profiles. A lower-bound
on the competitive rate gap is derived and a new online policy is
presented. The new online policy is shown to perform very close
to the competitive rate gap lower-bound for any number of slots
and to outperform previously proposed online policies, such us
the myopic policy.
