论文摘要
在本文中，我们为室内光学无线通信（OWC）大规模物联网（IoT）方案设计了一种新颖的高通量随机访问方案。由于两个物联网设备和OWC访问点（AP）的密度很高，因此我们将提出的方案以多接收器编码的插入式Aloha为基础。在这种情况下，APS的碰撞通过集中干扰取消解码器解决，该解码器可能会利用空间和时间多样性。通过应用每个OWC AP视野（FOV）的自适应控制，提出的系统能够动态适应不同的物联网设备激活率，以保持高总吞吐量。使用说明性仿真结果，我们证明了所提出方法的设计方法和性能可能性。
In this paper, we design a novel high-throughput random access scheme for an indoor optical wireless communication (OWC) massive Internet of Things (IoT) scenario. Due to the large density of both IoT devices and OWC access points (APs), we base the proposed scheme on multi-receiver coded slotted ALOHA. In this scenario, collisions at APs are resolved by a centralized interference cancellation decoder that may exploit both spatial and temporal diversity. By applying adaptive control of each OWC AP field of view (FOV), the proposed system is able to dynamically adapt to different IoT device activation rates, in order to maintain a high total throughput. Using illustrative simulation results, we demonstrate the design methodology and performance possibilities of the proposed method.
