• In this paper, a point-to-point communication system in a wireless body area network capable of harvesting radio-energy is studied. We investigate two scenarios for transmission, which are in normal circumstance and in abnormal circumstance. We consider power splitting protocol in normal circumstance and time switching protocol in abnormal circumstance at the sensor, respectively. Based on two protocols, the optimal power splitting and time switching ratios are derived in each scenario. The goal of this paper is to maximize the information throughput from the sensor to the access point in uplink by balancing the time duration among the command transfer phase, the energy harvesting phase, and the information transfer phase while satisfying energy harvesting and consumption balance constraint at the sensor. Numerical results demonstrate the effectiveness of the optimal solution.
