Maximizing Spectral Efficiency for Energy Harvesting-Aware WBAN.

In this paper, we investigate the spectral efficiency of a communication link in a wireless body area network (WBAN) capable of harvesting energy from the environment. We consider two scenarios for the transmission which are single- and dual-hop and achieve the power management policy for each scenario. In the first scenario, the aim is to maximize the link's spectral efficiency over N time slots subject to the battery capacity, energy harvesting constraint, and WBAN limitations including power and outage probability.
