本文研究了一种能够收集无线电能量的无线体域网中的点对点通信系统。我们研究了两种情况下的传输，这是在正常情况下，在异常情况下。在传感器端分别考虑了正常情况下的功率分配协议和异常情况下的时间切换协议。基于两个协议，最佳的功率分配和时间切换比推导出在每种情况下。本文的目标是最大化的信息吞吐量从传感器到接入点在上行链路中的命令传输阶段，能量收集阶段，和信息传输阶段之间的时间持续时间的平衡，同时满足能量收集和消耗平衡约束的传感器。数值结果验证了最优解的有效性。
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.
