Abstract

This paper investigates the outage performance of simultaneous wireless information and power transfer (SWIPT)-assisted device-to-device (D2D)-based hybrid satellite-terrestrial networks (HSTNs). In the considered system, an energy-constrained terrestrial user terminal (UT) harvests energy from the radio frequency (RF) signal of a terrestrial amplify-and-forward (AF) relay and utilizes the harvested energy to cooperate with the shadowed terrestrial Internet of Things (IoT) devices in a D2D communication. Both power splitting (PS)-based and time switching (TS)-based SWIPT-D2D schemes are adopted by the energy-constrained UT to obtain sustainable energy for transmitting information to the shadowed IoT device. Considering shadowed Rician fading for satellite-terrestrial links and Nakagami- fading for terrestrial links, we analyze the system performance by deriving the closed-form expressions for the outage probability (OP) of both the UT and the IoT device. Our theoretical analyses are validated via Monte Carlo simulations.

摘要

本文研究了基于同时无线信息与能量传输（SWIPT）的设备到设备（D2D）混合卫星 - 地面网络（HSTN）的中断性能。在所考虑的系统中，一个能量受限的地面用户终端（UT）从地面放大转发（AF）中继的射频（RF）信号中收集能量，并利用收集到的能量在D2D通信中与处于阴影中的地面物联网（IoT）设备进行协作。能量受限的UT采用基于功率分割（PS）和基于时间切换（TS）的SWIPT - D2D方案，以获取可持续能量用于向处于阴影中的物联网设备传输信息。考虑到卫星 - 地面链路的阴影莱斯衰落和地面链路的 Nakagami 衰落，我们通过推导UT和物联网设备中断概率（OP）的闭式表达式来分析系统性能。我们的理论分析通过蒙特卡罗模拟得到验证。
