Query: Recent Results on Proportional Fair Scheduling for mmWave-based
  Industrial Wireless Networks   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.
