论文摘要
我们考虑了一个继电器插入的Aloha解决方案，用于上行链路随机访问光学无线通信（OWC）的物联网（IoT）。上行链路的第一阶段是IoT设备和继电器之间的一个阶段，使用室内OWC实现，而继电器和基站之间的第二阶段代表基于基于低功率大区域网络的远程RF传输，例如Lorawan，例如Lorawan，并发生在室外。观察到OWC和RF通道条件的吞吐量性能依赖性。在不同的渠道和交通条件下突出显示并研究了由于添加继电器而产生的性能增益的行为。
We consider a relay-aided Slotted ALOHA solution for uplink random access for an Optical Wireless Communications (OWC)-based Internet of Things (IoT). The first phase of uplink, the one between IoT devices and the relays, is realized using indoor OWC, while the second phase, between the relays and a base station, represents the long-range RF transmission based on low-power wide area network such as LoRaWAN and occurs outdoors. The throughput performance dependence on the OWC and RF channel conditions is observed. The behavior of the performance gain due to adding relays is highlighted and investigated under different channel and traffic conditions.
