论文摘要
在本文中，我们分析了异质毫米波（MMWave）无线电源转移（WPT）网络的能量覆盖范围，其中宏基站（MBSS）根据Poisson Point Process（PPP）的位置分配，POISSON POINT过程（PBS）的位置（PBS）的位置，围绕着$ K $ -Tier Poisson Poisson Poisson和PCP的PCP，PCP和PCP的pcpuster（PCP），并且集群。此外，采用了余弦天线增益模型，而不是普遍的襟翼顶增益模型，该模型在推导方面更简单，但准确。基于广义指数分布近似，我们提出了一种新技术，以推导随机部署的MMWave WPT网络的能量覆盖概率。具体而言，以托马斯群集过程（TCP）为例，我们使用两个PB关联策略（即随机PB关联和最近的PB关联）得出能量覆盖概率。通过蒙特卡罗模拟，我们的理论结果得到了验证，还研究了系统参数的影响，例如群集中阵列天线大小，能量阈值或PBS的平均数量。
In this paper, we analyze the energy coverage performance of heterogeneous millimeter wave (mmWave) wireless power transfer (WPT) networks, where macro base stations (MBSs) are distributed according to a Poisson point process (PPP), the location of power beacons (PBs) is modeled as a $k$-tier Poisson cluster process (PCP), and energy users (EUs) are clustered around the centers of PB clusters. Moreover, the cosine antenna gain model is adopted instead of the prevalent flap-top gain model, which is simpler in derivation but less accurate. Based on the generalized exponential distribution approximation, we propose a new technique of deriving the energy coverage probability of randomly deployed mmWave WPT networks. Specifically, taking the Thomas cluster process (TCP) for instance, we derive the energy coverage probabilities with two PB association strategies, i.e., the random PB association and the nearest PB association. Through Monte-Carlo simulations, our theoretical results are verified and the impact of system parameters, such as the array antenna size, energy threshold or average number of PBs in a cluster, are also investigated.
