Millimeter wave (mmWave) communication has recently attracted significant attention from both industrial and academic communities. The large bandwidth availability as well as low interference nature of mmWave spectrum is particularly attractive for industrial communication. However, inherent challenges such as coverage and blockage of mmWave communication cause highly fluctuated channel quality. This paper explores wireless medium access control (MAC) schedulers for mmWave-based industrial wireless applications. Our objective is to design a high-performance and enhanced fairness MAC scheduling algorithm that responds rapidly to channel variations. The key contribution of our work is a method to modify the standard proportional fair (SPF) scheduler. It introduces more flexibility and dynamic properties. Compared to the SPF, our enhanced proportional fair (EPF) scheduler not only improves the priority for users in poor channel conditions but also accelerates the reaction time in fluctuated channel conditions. By providing higher fairness for all users and enhancing system robustness, it particularly adapts to the scatter-rich industrial mmWave communication environment. Through extensive performance evaluation based on the widely accepted network simulator (ns-3), we show that the new scheduler achieves better performance in terms of delivering ultra-low latency and reliable services over mmWave-based industrial communication.

基于毫米波的工业无线网络的比例公平调度的最新结果

毫米波 (mmWave) 通信最近引起了工业界和学术界的极大关注。毫米波频谱的大带宽可用性和低干扰特性对工业通信特别有吸引力。然而，毫米波通信的覆盖和阻塞等固有挑战会导致信道质量高度波动。本文探讨了用于基于毫米波的工业无线应用的无线媒体访问控制 (MAC) 调度程序。我们的目标是设计一种高性能且增强公平性的 MAC 调度算法，以快速响应信道变化。我们工作的主要贡献是修改标准比例公平 (SPF) 调度程序的方法。它引入了更多的灵活性和动态特性。与SPF相比，我们的增强型比例公平 (EPF) 调度器不仅提高了信道条件较差的用户的优先级，而且还加快了信道条件波动时的反应时间。通过为所有用户提供更高的公平性和增强系统的鲁棒性，它特别适应了散射丰富的工业毫米波通信环境。通过基于广泛接受的网络模拟器 (ns-3) 的广泛性能评估，我们表明新调度器在通过基于毫米波的工业通信提供超低延迟和可靠服务方面实现了更好的性能。它特别适应散射丰富的工业毫米波通信环境。通过基于广泛接受的网络模拟器 (ns-3) 的广泛性能评估，我们表明新调度器在通过基于毫米波的工业通信提供超低延迟和可靠服务方面实现了更好的性能。它特别适应散射丰富的工业毫米波通信环境。通过基于广泛接受的网络模拟器 (ns-3) 的广泛性能评估，我们表明新调度器在通过基于毫米波的工业通信提供超低延迟和可靠服务方面实现了更好的性能。
