无线供电通信网络（WPCN）是一种集无线信息传输（WIT）和无线能量传输（WET）于一体的新型网络架构。为了提高该网络的性能，有必要设计一种调度方法，该方法为整个网络中的WIT和WET提供适当的机会。用于WPCN的收获然后接入协议由具有在随机接入持续时间之前的WET收获持续时间的简单帧结构组成。这种帧结构减少了相当大的开销和复杂性，并且适合于WPCN。然而，没有分析模型的收获，然后访问协议的WPCN已提出到目前为止。在本文中，我们扩展了分析模型的基础上的能量消耗模型，并提出了一个性能分析的收获后接入协议的WPCN。通过从分析模型中获得适当的帧大小，我们提供了一个适当的机会，通过WET和信息传输到整个网络的能量收集，这有助于吞吐量的提高。通过与分析和仿真结果的比较，证明了所提出的模型的有效性。所提出的模型还阐明了收割后接入协议的吞吐量和能源效率方面的特点。
A wireless powered communication network (WPCN) is a novel network architecture that integrates wireless information transfer (WIT) and wireless energy transfer (WET). To improve the performance of this network, it is necessary to design a scheduling method that provides appropriate opportunities for WIT as well as WET throughout the network. The Harvest-then-access protocol for the WPCN consists of a simple frame structure with a WET harvesting duration preceding the random access duration. This frame structure reduces considerable overhead and complexity and is suitable for WPCN. However, no analytical model of the Harvest-then-Access protocol for WPCN has been proposed so far. In this paper, we extend the analytical model based on the energy queueing model and propose a performance analysis of the Harvest-then-Access protocol for WPCN. By deriving the appropriate frame size from the analytical model, we provide an appropriate opportunity for energy harvesting by WET and information transmission to the entire network, which contributes to throughput improvement. The validity of the proposed model is demonstrated by comparison with analytical and simulation results. The proposed model also clarifies the characteristics of the Harvest-then-Access protocol in terms of throughput and energy efficiency.
