The autonomy of wireless nodes is dropping year after year as the battery capacity increase is not able to follow the increasing energy consumption of the nodes, which is produced due to the high demand of data traffic and transmitter processing complexity of the users. Energy harvesting and energy efficient communications, e.g., energy efficient network topologies, are promising solutions to overcome this problem. In this context, this paper studies the power allocation and slot selection strategies that maximize the total throughput of a wireless energy harvesting node by taking into account both the transmission power and circuitry power consumption spent along the radio frequency chain of the transmitter.
