在本文中，我们提供了一种无线供电传感器网络(WPSN)的高层抽象系统模型，该模型基于真实环境下的实验结果。在WPSN中，传感器节点由来自专用射频电源的射频(RF)能量传输来无线供电。我们定义了组成WPSN的每个组件的行为，并分析了这些组件之间的交互，从系统的角度建立了一个现实的WPSN模型。为此，我们为WPSN实现了一个真实的、成熟的测试平台，并进行了大量的实验，以获取模型参数并验证所提出的模型。基于该WPSN模型，我们提出了一种WPSN的能量管理方案，该方案在保证能量中性运行的同时最大化了射频能量传输效率。我们在一个真实的试验台上实现了所提出的能量管理方案，并展示了它的运行和性能。
In this paper, we provide a high-level abstract system model of a wireless-powered sensor network (WPSN) based on experimental results on a real-life testbed. In the WPSN, a sensor node is wirelessly powered by the radio frequency (RF) energy transfer from a dedicated RF power source. We define the behavior of each component comprising the WPSN and analyze the interaction between these components to set up a realistic WPSN model from the systematic point of view. Towards this, we implement a real-life and full-fledged testbed for the WPSN and conduct extensive experiments to obtain model parameters and to validate the proposed model. Based on this WPSN model, we propose an energy management scheme for the WPSN, which maximizes RF energy transfer efficiency while guaranteeing energy neutral operation. We implement the proposed energy management scheme in a real testbed and show its operation and performance.
