Abstract

There has been recent research effort on understanding data transmission with an energy harvesting transmitter that has a rechargeable battery for green communications [1–4]. Recently, based on [3, 5] further investigates the issues of power allocation problems to minimize the grid power consumption with random energy and data arrival. In more detail, for the implied problem that is a convex optimization problem, rather than the original non-convex problem, a solution is computed. For convenience and without loss of generality, the process is considered as a discrete time process. The simplest and useful system model, illustrated in Fig. 5.1, assumes that there are K epochs in the time period (0, T]. For each epoch, an event occurs which may be the consequence of channel fading gain variation or new energy arrival, or both. This setting leads to new design insights in a wireless link with a rechargeable transmitter and fading channels.
